In immunocompromised hosts, infection Canbe life-threatening as no effective treatments are currently available to control infection. To increase our understanding of the mechanisms that play a role in host-parasite interactions at the level of the immune response, we investigated the effects of Cryptosporidium parvum antigen (CPA) on bone marrow-derived (DCS). Herein we examined cytokine secretion and cell surface marker expression on DCs exposed to CPA. We also measured cytokine production in CD4+ cells co-cultured with CPA primed DCs in the presence of anti-CD3. CPA induced a significant increase in the production of interleukin(IL)-12p40, IL-10, IL-6, and TNF-α by DCs and enhanced the expression of the cell surface markers TLR4, CD80, CD86, and MHC11. CPA primed DC co-cultured in the presence of anti-CD3 with CD4+ T-cells inhibited the secretion of Th2 associated cytokines, notably IL-5 and IL-13, with no effects on the secretions of interferon (IFN)-γ, IL-2, IL-17, and IL-10. These findings support studies in the literature that CPA can induce the full maturation of DCs that subsequently initiate Th1 immune responses critical to the resolution of C. parvum infection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptosporidium%20parvum" title="cryptosporidium parvum">cryptosporidium parvum</a>, <a href="https://publications.waset.org/abstracts/search?q=dendritic%20cells" title=" dendritic cells"> dendritic cells</a>, <a href="https://publications.waset.org/abstracts/search?q=IL-12%20p70" title=" IL-12 p70"> IL-12 p70</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20surface%20marker" title=" cell surface marker"> cell surface marker</a> </p> <a href="https://publications.waset.org/abstracts/143746/cryptosporidium-parvum-oocytic-antigen-induced-a-pro-inflammatory-dc-phenotype" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143746.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">173</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Importance of Cryptosporidiosis in Dairy Calves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Asadpour">Mohammad Asadpour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cryptosporidium spp. is zoonotic pathogens transmissible from a variety of animals to humans and is a considerable public health concern. Calves have been identified in numerous reports as a major source of environmental contamination with this pathogen. Parasite has a different species that are the cases of zoonotic disease in immunodeficient people and neonatal calves. Cryptosporidium oocysts are extremely resistant to chlorine and other physical cases that commonly used in drinking water. Reproduction of resistant oocytes is a way for this monoxenous parasite to remain in the environment. Cryptosporidium parvum is the most important species that has human and cattle genotypes. Cryptosporidium is one of the most important causes of diarrhea in neonatal calves and also, one of the four causes of diarrhea symptoms in pre-weaned calves. Because of the incompetent immune system in calves, Cryptosporidium infection is the cause of a lot of problems in raising farms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cryptosporidium%20spp" title="Cryptosporidium spp">Cryptosporidium spp</a>, <a href="https://publications.waset.org/abstracts/search?q=dairy%20calves" title=" dairy calves"> dairy calves</a>, <a href="https://publications.waset.org/abstracts/search?q=importance" title=" importance"> importance</a>, <a href="https://publications.waset.org/abstracts/search?q=veterinary%20medicine" title=" veterinary medicine"> veterinary medicine</a> </p> <a href="https://publications.waset.org/abstracts/5549/importance-of-cryptosporidiosis-in-dairy-calves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5549.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">583</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Identification and Molecular Characterization of Cryptosporidium Spp. in Pre-Wean Dairy Calves in Mashhad, Northeastern of Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Asadpour">Mohammad Asadpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Gholamreza%20Razmi"> Gholamreza Razmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gholamreza%20Mohammadi"> Gholamreza Mohammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abolghasem%20Naghibi"> Abolghasem Naghibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cryptosporidium Spp., protozoan parasites of the phylum Apicomplexa, have a wide spectrum of hosts including humans, domestic animals and wild mammals, birds, reptiles, amphibians and fish. Dairy cattle have been identified in numerous reports as a major source of environmental contamination with this pathogen. In this study, a Polymerase Chain Reaction (PCR), Restriction Fragment Length Polymorphism (RFLP) analysis of the Small-Subunit (SSU) rRNA gene was used to detect and identify Cryptosporidium Spp. in 300 fecal specimens from 1 to 30 days pre-wean calves in 10 farms in Mashhad, Iran. Eighty five (28.3%) and forty five (15%) of the specimens were positive for Cryptosporidium by microscopic and PCR examination respectively. Restriction digestion of the PCR products by VSPI and Ssp1 restriction enzymes and analysis of sequence data revealed the presence of C. parvum, bovine genotype in all isolates. Our findings suggest that cattle can be a source of Cryptosporidial infections for humans and animals in Mashhad area.

We also wish to determine the molecular biology definitions of the species and genotypes of microsporidia and Cryptosporidium in HIV patients. In this cross-sectional study, carried out in Kinshasa, Democratic Republic of the Congo, stool samples were collected from 242 HIV patients (87 men and 155 women) with referred symptoms and risk factors for opportunistic intestinal parasites. The analysis of feces specimen were performed using Ziehl–Neelsen stainings, real-time polymerase chain reaction (PCR), immunofluorescence indirect monoclonal antibody, nested PCR-restriction fragment length polymorphism, and PCR amplification and sequencing. Odds ratio (OR) and 95% confidence intervals were used to quantify the risk. Of the 242 HIV patients, 7.8%, 0.4%, 5.4%, 0.4%, 2%, 10.6%, and 2.8% had Enterocytozoon bieneusi, Encephalitozoon intestinalis, Cryptosporidium spp., Isospora belli, pathogenic intestinal protozoa, nonpathogenic intestinal protozoa, and helminths, respectively. We found five genotypes of E. bieneusi: two older, NIA1 and D, and three new, KIN1, KIN2, and KIN3. Only 0.4% and 1.6% had Cryptosporidium parvum and Cryptosporidium hominis, respectively. Of the patients, 36.4%, 34.3%, 31%, and 39% had asthenia, diarrhea, a CD4 count of ,100 cells/mm³, and no antiretroviral therapy (ART), respectively. The majority of those with opportunistic intestinal parasites and C. hominis, and all with C. parvum and new E. bieneusi genotypes, had diarrhea, low CD4+ counts of ,100 cells/mm³, and no ART. There was a significant association between Entamoeba coli, Kaposi sarcoma, herpes zoster, chronic diarrhea, and asthenia, and the presence of 28 cases with opportunistic intestinal parasites. Rural areas, public toilets, and exposure to farm pigs were the univariate risk factors present in the 28 cases with opportunistic intestinal parasites. In logistic regression analysis, a CD4 count of ,100 cells/mm³ (OR = 4.60; 95% CI 1.70–12.20; P = 0.002), no ART (OR = 5.00; 95% CI 1.90–13.20; P , 0.001), and exposure to surface water (OR = 2.90; 95% CI 1.01–8.40; P = 0.048) were identified as the significant and independent determinants for the presence of opportunistic intestinal parasites. E. bieneusi and Cryptosporidium are becoming more prevalent in Kinshasa, Congo. Based on the findings, we recommend epidemiology surveillance and prevention by means of hygiene, the emphasis of sensitive PCR methods, and treating opportunistic intestinal parasites that may be acquired through fecal–oral transmission, surface water, normal immunity, rural area-based person–person and animal–human nfection, and transmission of HIV. Therapy, including ART and treatment with fumagillin, is needed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diarrhea" title="diarrhea">diarrhea</a>, <a href="https://publications.waset.org/abstracts/search?q=enterocytozoon%20bieneusi" title=" enterocytozoon bieneusi"> enterocytozoon bieneusi</a>, <a href="https://publications.waset.org/abstracts/search?q=cryptosporidium%20hominis" title=" cryptosporidium hominis"> cryptosporidium hominis</a>, <a href="https://publications.waset.org/abstracts/search?q=cryptosporidium%0D%0Aparvum" title=" cryptosporidium parvum"> cryptosporidium parvum</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=africans" title=" africans"> africans</a> </p> <a href="https://publications.waset.org/abstracts/149819/epidemiology-clinical-immune-and-molecular-profiles-of-microsporidiosis-and-cryptosporidiosis-among-hivaids-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149819.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">125</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Detection of Cryptosporidium Oocysts by Acid-Fast Staining Method and PCR in Surface Water from Tehran, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Mohsen%20Homayouni">Mohamad Mohsen Homayouni</a>, <a href="https://publications.waset.org/abstracts/search?q=Niloofar%20Taghipour"> Niloofar Taghipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Reza%20Memar"> Ahmad Reza Memar</a>, <a href="https://publications.waset.org/abstracts/search?q=Niloofar%20Khalaji"> Niloofar Khalaji</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Kiani"> Hamed Kiani</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyyed%20Javad%20Seyyed%20Tabaei"> Seyyed Javad Seyyed Tabaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Objective: Cryptosporidium is a coccidian protozoan parasite; its oocysts in surface water are a global health problem. Due to the low number of parasites in the water resources and the lack of laboratory culture, rapid and sensitive method for detection of the organism in the water resources is necessarily required. We applied modified acid-fast staining and PCR for the detection of the Cryptosporidium spp. and analysed the genotypes in 55 samples collected from surface water. Methods: Over a period of nine months, 55 surface water samples were collected from the five rivers in Tehran, Iran. The samples were filtered by using cellulose acetate membrane filters. By acid fast method, initial identification of Cryptosporidium oocyst were carried out on surface water samples. Then, nested PCR assay was designed for the specific amplification and analysed the genotypes. Results: Modified Ziehl-Neelsen method revealed 5–20 Cryptosporidium oocysts detected per 10 Liter. Five out of the 55 (9.09%) surface water samples were found positive for Cryptosporidium spp. by Ziehl-Neelsen test and seven (12.7%) were found positive by nested PCR. The staining results were consistent with PCR. Seven Cryptosporidium PCR products were successfully sequenced and five gp60 subtypes were detected. Our finding of gp60 gene revealed that all of the positive isolates were Cryptosporidium parvum and belonged to subtype families IIa and IId. Conclusion: Our investigations were showed that collection of water samples were contaminated by Cryptosporidium, with potential hazards for the significant health problem. This study provides the first report on detection and genotyping of Cryptosporidium species from surface water samples in Iran, and its result confirmed the low clinical incidence of this parasite on the community. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cryptosporidium%20spp." title="Cryptosporidium spp.">Cryptosporidium spp.</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20filtration" title=" membrane filtration"> membrane filtration</a>, <a href="https://publications.waset.org/abstracts/search?q=subtype" title=" subtype"> subtype</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20water" title=" surface water"> surface water</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran" title=" Iran"> Iran</a> </p> <a href="https://publications.waset.org/abstracts/78803/detection-of-cryptosporidium-oocysts-by-acid-fast-staining-method-and-pcr-in-surface-water-from-tehran-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78803.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">416</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Prevalence of Cryptosporidium spp. in Free-Living Wild Birds by Using Carbol Fuchsin Staining Methods in Konya, Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nermin%20Isik">Nermin Isik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cryptosporidiosis is one of the most common parasitic infection in domesticated, caged, wild birds. Cryptosporidium sp. has been reported in over 30 avian species worldwide. Cryptosporidium meleagridis, Cryptosporidium baileyi and Cryptosporidium galli are recognised avian species of Cryptosporidium. This study was carried out to determine the prevalance of Cryptosporidium sp. in wild birds in Konya province, Turkey. Faecal samples were collected from 65 wild birds including 52 Podicipedidae (Podiceps cristatus), 11 Rallidae (Fulicia Atra), 2 Anitadia (Aytha ferina). Faecal samples were stained with Modified Ziehl-Neelsen staining technigue, they were examined under light microscope for the presence of Cryptosporidium sp. oocyts. Among the 65 faecal samples, 11 (16.9%) were found to be infected with Cryptosporidium sp. oocysts. The results of this study indicate that wild birds may play an important role in the epidemiology of Cryptosporidium. In conclusion, Cryptosporidiosis has suggested zoonotic potential and thus warrant further attention. In addition, biological and genetic studies are required to provide more information on Cryptosporidiosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cryptosporidium%20sp" title="Cryptosporidium sp">Cryptosporidium sp</a>, <a href="https://publications.waset.org/abstracts/search?q=wild%20birds" title=" wild birds"> wild birds</a>, <a href="https://publications.waset.org/abstracts/search?q=Konya" title=" Konya"> Konya</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkey" title=" Turkey"> Turkey</a> </p> <a href="https://publications.waset.org/abstracts/50934/prevalence-of-cryptosporidium-spp-in-free-living-wild-birds-by-using-carbol-fuchsin-staining-methods-in-konya-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50934.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">359</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> In Silico Screening, Identification and Validation of Cryptosporidium hominis Hypothetical Protein and Virtual Screening of Inhibitors as Therapeutics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arpit%20Kumar%20Shrivastava">Arpit Kumar Shrivastava</a>, <a href="https://publications.waset.org/abstracts/search?q=Subrat%20Kumar"> Subrat Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajani%20Kanta%20Mohapatra"> Rajani Kanta Mohapatra</a>, <a href="https://publications.waset.org/abstracts/search?q=Priyadarshi%20Soumyaranjan%20Sahu"> Priyadarshi Soumyaranjan Sahu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Computational approaches to predict structure, function and other biological characteristics of proteins are becoming more common in comparison to the traditional methods in drug discovery. Cryptosporidiosis is a major zoonotic diarrheal disease particularly in children, which is caused primarily by Cryptosporidium hominis and Cryptosporidium parvum. Currently, there are no vaccines for cryptosporidiosis and recommended drugs are not effective. With the availability of complete genome sequence of C. hominis, new targets have been recognized for the development of effective and better drugs and/or vaccines. We identified a unique hypothetical epitopic protein in C. hominis genome through BLASTP analysis. A 3D model of the hypothetical protein was generated using I-Tasser server through threading methodology. The quality of the model was validated through Ramachandran plot by PROCHECK server. The functional annotation of the hypothetical protein through DALI server revealed structural similarity with human Transportin 3. Phylogenetic analysis for this hypothetical protein also showed C. hominis hypothetical protein (CUV04613) was the closely related to human transportin 3 protein. The 3D protein model is further subjected to virtual screening study with inhibitors from the Zinc Database by using Dock Blaster software. Docking study reported N-(3-chlorobenzyl) ethane-1,2-diamine as the best inhibitor in terms of docking score. Docking analysis elucidated that Leu 525, Ile 526, Glu 528, Glu 529 are critical residues for ligand–receptor interactions. The molecular dynamic simulation was done to access the reliability of the binding pose of inhibitor and protein complex using GROMACS software at 10ns time point. Trajectories were analyzed at each 2.5 ns time interval, among which, H-bond with LEU-525 and GLY- 530 are significantly present in MD trajectories. Furthermore, antigenic determinants of the protein were determined with the help of DNA Star software. Our study findings showed a great potential in order to provide insights in the development of new drug(s) or vaccine(s) for control as well as prevention of cryptosporidiosis among humans and animals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptosporidium%20hominis" title="cryptosporidium hominis">cryptosporidium hominis</a>, <a href="https://publications.waset.org/abstracts/search?q=hypothetical%20protein" title=" hypothetical protein"> hypothetical protein</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20docking" title=" molecular docking"> molecular docking</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics%20simulation" title=" molecular dynamics simulation"> molecular dynamics simulation</a> </p> <a href="https://publications.waset.org/abstracts/64733/in-silico-screening-identification-and-validation-of-cryptosporidium-hominis-hypothetical-protein-and-virtual-screening-of-inhibitors-as-therapeutics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64733.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">365</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> A Survey on Frequency of Cryptosporidiosis and Giardiasis in Horses in Ahvaz South-West of Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20R.%20Ghadrdan-Mashhadi">Ali R.

Although, the infection to these parasites rarely caused to illness in horses, but some veterinarian recorded the clinical signs (such as diarrhea and malabsorbtion) especially in foals. In present study, the frequency of Cryptosporidiosis and Giardiasis in horses in Ahvaz investigated. The feces samples were taken from 100 horses that keep in seven horse breeding clubs, during spring and summer. The ages of horses were from 1 month to 27 years old. Fecal samples were stained by modified Ziehl-Neelsen and Tri-chrome methods. Results were analyzed with Chi-square Test and Fisher’s exact test. The results showed that the rate of infection to Cryptosporidium and Giardia were 18% and 40%, respectively. There weren't significant differences between infection to Cryptosporidium and Giardia with sex, age and fecal constancy. Although, the rate of infection to Cryptosporidium in studied horses is very similar to other studies but it seems, the rate of infection to Giardia is high in compare to other studies were done in the other countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahvaz" title="Ahvaz">Ahvaz</a>, <a href="https://publications.waset.org/abstracts/search?q=cryptosporidium" title=" cryptosporidium"> cryptosporidium</a>, <a href="https://publications.waset.org/abstracts/search?q=giardia" title=" giardia"> giardia</a>, <a href="https://publications.waset.org/abstracts/search?q=horse" title=" horse"> horse</a> </p> <a href="https://publications.waset.org/abstracts/39460/a-survey-on-frequency-of-cryptosporidiosis-and-giardiasis-in-horses-in-ahvaz-south-west-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39460.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">363</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Determination of Some Etiologic Agents in Calves with Diarrhea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nermin%20Isik">Nermin Isik</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozlem%20Derinbay%20Ekici"> Ozlem Derinbay Ekici</a>, <a href="https://publications.waset.org/abstracts/search?q=Oguzhan%20Avci"> Oguzhan Avci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to determination of role infection in neonatal calves in Central Anatolian, Turkey. A total 300 fecal samples were collected from diarrheic neonatal calves, aged between 0–90 days from Konya, Karaman, and Aksaray from January to April 2014. Fecal specimens from calves with clinically diarrheic symptoms were examined for the presence of Bovine Coronavirus, Bovine Rotavirus, Cryptosporidium sp., and E. coli by commercially available capture direct enzyme linked immunosorbent assay (ELISA) kit and Modified Ziehl Neelsen method (MZN). Calves were grouped according to their age as follows: 1-14, 15-29, and 30-90 days. Cryptosporidium sp. infection was detected in 52.8%, 58.8%, and 39.2% by ELISA and 33.9%, 47%, 26.7% by MZN in the respective age groups. The seroprevalance of Rotavirus (12.5 %, 40 %, 12.5 %), Coronavirus (2.5%, 0%, 3.5%) and E. coli (5%, 4.7%, 8.9%) infections were determined according to the age groups respectively. Cryptosporidium sp. was the most detected enteropathogen (52 %) of calves and coronavirus was the least detected (2 %). The detection rate of the mixed enfection was 12.3%.

Aim of the study was to evaluate the coinfection rate with opportunistic protozoal agents among Bulgarian patients diagnosed with P. jirovecii pneumonia. Thirty-eight pulmonary samples were collected from 38 patients (28 HIV-infected) with P. jirovecii infection. P. jirovecii DNA was detected by real-time PCR targeting the large mitochondrial subunit ribosomal RNA gene. Acanthamoeba was determined by genus-specific conventional PCR assay. Real-time PCR for the detection of a Toxoplasma gondii and Cryptosporidium DNA fragment was used. Pneumocystis DNA was detected in all 38 specimens; 28 (73.7%) were from HIV-infected patients. Three (10,7%) of them were co-infected with T. gondii and 1 (3.6%) with Cryptosporidium. In the group of non-HIV-infected (n=10), Cryptosporidium DNA was detected in an infant (10%). Acanthamoeba DNA was not found in the tested samples. The current study showed a relatively low rate of coinfections of Cryptosporidium spp./T. gondii and P. jirovecii in the Bulgarian patients studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coinfection" title="coinfection">coinfection</a>, <a href="https://publications.waset.org/abstracts/search?q=opportunistic%20protozoal%20agents" title=" opportunistic protozoal agents"> opportunistic protozoal agents</a>, <a href="https://publications.waset.org/abstracts/search?q=Pneumocystis%20jirovecii" title=" Pneumocystis jirovecii"> Pneumocystis jirovecii</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20infections" title=" pulmonary infections"> pulmonary infections</a> </p> <a href="https://publications.waset.org/abstracts/151450/study-on-the-presence-of-protozoal-coinfections-among-patients-with-pneumocystis-jirovecii-pneumonia-in-bulgaria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151450.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">154</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Incidence and Etiology of Neonatal Calf Diarrhea in the Region of Blida, Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Dadda">A.

A total of 324 claves, housed in 30 dairy breeding were followed during two velage season from January to Juan 2013. The total mortality was 5,9% and was significantly higher in calves had less than 15 days of age. The incidence rate of diarrhea was 31,5% and peaked in the first two weeks after velage. The main causes were breeding controls, defect of passive immunity, old of calf, production season, and nutrient of pregnant cattle, veal’s housing and infectious agents. ELISA test on 22 fecal samples revealed that the 31, 82% of dairy breeding were infected, by cryptosporidium parvum in 13, 6% of study population, E.Coli F5 in 9% and Rotavirus with rate of 4, 5%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diarrhoea" title="diarrhoea">diarrhoea</a>, <a href="https://publications.waset.org/abstracts/search?q=neonatal" title=" neonatal"> neonatal</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=aetiology" title=" aetiology"> aetiology</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=incidence" title=" incidence"> incidence</a> </p> <a href="https://publications.waset.org/abstracts/16257/incidence-and-etiology-of-neonatal-calf-diarrhea-in-the-region-of-blida-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16257.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">635</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Foodborne Outbreak Calendar: Application of Time Series Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ryan%20B.%20Simpson">Ryan B.

Naumova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Centers for Disease Control and Prevention (CDC) estimate that 31 known foodborne pathogens cause 9.4 million cases of these illnesses annually in US. Over 90% of these illnesses are associated with exposure to Campylobacter, Cryptosporidium, Cyclospora, Listeria, Salmonella, Shigella, Shiga-Toxin Producing E.Coli (STEC), Vibrio, and Yersinia. Contaminated products contain parasites typically causing an intestinal illness manifested by diarrhea, stomach cramping, nausea, weight loss, fatigue and may result in deaths in fragile populations. Since 1998, the National Outbreak Reporting System (NORS) has allowed for routine collection of suspected and laboratory-confirmed cases of food poisoning. While retrospective analyses have revealed common pathogen-specific seasonal patterns, little is known concerning the stability of those patterns over time and whether they can be used for preventative forecasting. The objective of this study is to construct a calendar of foodborne outbreaks of nine infections based on the peak timing of outbreak incidence in the US from 1996 to 2017. Reported cases were abstracted from FoodNet for Salmonella (135115), Campylobacter (121099), Shigella (48520), Cryptosporidium (21701), STEC (18022), Yersinia (3602), Vibrio (3000), Listeria (2543), and Cyclospora (758). Monthly counts were compiled for each agent, seasonal peak timing and peak intensity were estimated, and the stability of seasonal peaks and synchronization of infections was examined. Negative Binomial harmonic regression models with the delta-method were applied to derive confidence intervals for the peak timing for each year and overall study period estimates. Preliminary results indicate that five infections continue to lead as major causes of outbreaks, exhibiting steady upward trends with annual increases in cases ranging from 2.71% (95%CI: [2.38, 3.05]) in Campylobacter, 4.78% (95%CI: [4.14, 5.41]) in Salmonella, 7.09% (95%CI: [6.38, 7.82]) in E.Coli, 7.71% (95%CI: [6.94, 8.49]) in Cryptosporidium, and 8.67% (95%CI: [7.55, 9.80]) in Vibrio. Strong synchronization of summer outbreaks were observed, caused by Campylobacter, Vibrio, E.Coli and Salmonella, peaking at 7.57 ± 0.33, 7.84 ± 0.47, 7.85 ± 0.37, and 7.82 ± 0.14 calendar months, respectively, with the serial cross-correlation ranging 0.81-0.88 (p < 0.001). Over 21 years, Listeria and Cryptosporidium peaks (8.43 ± 0.77 and 8.52 ± 0.45 months, respectively) have a tendency to arrive 1-2 weeks earlier, while Vibrio peaks (7.8 ± 0.47) delay by 2-3 weeks. These findings will be incorporated in the forecast models to predict common paths of the spread, long-term trends, and the synchronization of outbreaks across etiological agents. The predictive modeling of foodborne outbreaks should consider long-term changes in seasonal timing, spatiotemporal trends, and sources of contamination. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foodborne%20outbreak" title="foodborne outbreak">foodborne outbreak</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20outbreak%20reporting%20system" title=" national outbreak reporting system"> national outbreak reporting system</a>, <a href="https://publications.waset.org/abstracts/search?q=predictive%20modeling" title=" predictive modeling"> predictive modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=seasonality" title=" seasonality"> seasonality</a> </p> <a href="https://publications.waset.org/abstracts/102947/foodborne-outbreak-calendar-application-of-time-series-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102947.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Multiple Etiologies and Incidences of Co-Infections in Childhood Diarrhea in a Hospital Based Screening Study in Odisha, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arpit%20K.%20Shrivastava">Arpit K.

Sahu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Acute diarrhea is one of the major causes of morbidity and mortality among children less than five years of age. Multiple etiologies have been implicated for infectious gastroenteritis causing acute diarrhea. In our study fecal samples (n=165) were collected from children (<5 years) presenting with symptoms of acute diarrhea. Samples were screened for viral, bacterial, and parasitic etiologies such as Rotavirus, Adenovirus, Diarrhoeagenic Escherichia coli (EPEC, EHEC, STEC, O157, O111), Shigella spp., Salmonella spp., Vibrio cholera, Cryptosporidium spp., and Giardia spp. The overall results from our study showed that 57% of children below 5 years of age with acute diarrhea were positive for at least one infectious etiology. Diarrhoeagenic Escherichia coli was detected to be the major etiological agent (29.09%) followed by Rotavirus (24.24%), Shigella (21.21%), Adenovirus (5.45%), Cryptosporidium (2.42%), and Giardia (0.60%). Among the different DEC strains, EPEC was detected significantly higher in <2 years children in comparison to >2 years age group (p =0.001). Concurrent infections with two or more pathogens were observed in 47 of 160 (28.48%) cases with a predominant incidence particularly in <2-year-old children (66.66%) compared to children of 2 to 5 years age group. Co-infection of Rotavirus with Shigella was the most frequent combination, which was detected in 17.94% cases, followed by Rotavirus with EPEC (15.38%) and Shigella with STEC (12.82%). Detection of multiple infectious etiologies and diagnosis of the right causative agent(s) can immensely help in better management of acute childhood diarrhea. In future more studies focusing on the detection of cases with concurrent infections must be carried out, as we believe that the etiological agents might be complementing each other’s strategies of pathogenesis resulting in severe diarrhea. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=children" title="children">children</a>, <a href="https://publications.waset.org/abstracts/search?q=co-infection" title=" co-infection"> co-infection</a>, <a href="https://publications.waset.org/abstracts/search?q=infectious%20diarrhea" title=" infectious diarrhea"> infectious diarrhea</a>, <a href="https://publications.waset.org/abstracts/search?q=Odisha" title=" Odisha"> Odisha</a> </p> <a href="https://publications.waset.org/abstracts/61397/multiple-etiologies-and-incidences-of-co-infections-in-childhood-diarrhea-in-a-hospital-based-screening-study-in-odisha-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61397.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">336</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> The Use of Non-Parametric Bootstrap in Computing of Microbial Risk Assessment from Lettuce Consumption Irrigated with Contaminated Water by Sanitary Sewage in Infulene Valley </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mario%20Tauzene%20Afonso%20Matangue">Mario Tauzene Afonso Matangue</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivan%20Andres%20Sanchez%20Ortiz"> Ivan Andres Sanchez Ortiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Metropolitan area of Maputo (Mozambique Capital City) is located in semi-arid zone (800 mm annual rainfall) with 1101170 million inhabitants. On the west side, there are the flatlands of Infulene where the Mulauze River flows towards to the Indian Ocean, receiving at this site, the storm water contaminated with sanitary sewage from Maputo, transported through a concrete open channel. In Infulene, local communities grow salads crops such as tomato, onion, garlic, lettuce, and cabbage, which are then commercialized and consumed in several markets in Maputo City. Lettuce is the most daily consumed salad crop in different meals, generally in fast-foods, breakfasts, lunches, and dinners. However, the risk of infection by several pathogens due to the consumption of lettuce, using the Quantitative Microbial Risk Assessment (QMRA) tools, is still unknown since there are few studies or publications concerning to this matter in Mozambique. This work is aimed at determining the annual risk arising from the consumption of lettuce grown in Infulene valley, in Maputo, using QMRA tools. The exposure model was constructed upon the volume of contaminated water remaining in the lettuce leaves, the empirical relations between the number of pathogens and the indicator of microorganisms (E. coli), the consumption of lettuce (g) and reduction of pathogens (days). The reference pathogens were Vibrio cholerae, Cryptosporidium, norovirus, and Ascaris. The water quality samples (E. coli) were collected in the storm water channel from January 2016 to December 2018, comprising 65 samples, and the urban lettuce consumption data were collected through inquiry in Maputo Metropolis covering 350 persons. A non-parametric bootstrap was performed involving 10,000 iterations over the collected dataset, namely, water quality (E. coli) and lettuce consumption. The dose-response models were: Exponential for Cryptosporidium, Kummer Confluent hypergeomtric function (1F1) for Vibrio and Ascaris Gaussian hypergeometric function (2F1-(a,b;c;z) for norovirus. The annual infection risk estimates were performed using R 3.6.0 (CoreTeam) software by Monte Carlo (Latin hypercubes), a sampling technique involving 10,000 iterations. The annual infection risks values expressed by Median and the 95th percentile, per person per year (pppy) arising from the consumption of lettuce are as follows: Vibrio cholerae (1.00, 1.00), Cryptosporidium (3.91x10⁻³, 9.72x 10⁻³), nororvirus (5.22x10⁻¹, 9.99x10⁻¹) and Ascaris (2.59x10⁻¹, 9.65x10⁻¹). Thus, the consumption of the lettuce would result in greater risks than the tolerable levels ( < 10⁻³ pppy or 10⁻⁶ DALY) for all pathogens, and the Vibrio cholerae is the most virulent pathogens, according to the hit-single models followed by the Ascaris lumbricoides and norovirus. The sensitivity analysis carried out in this work pointed out that in the whole QMRA, the most important input variable was the reduction of pathogens (Spearman rank value was 0.69) between harvest and consumption followed by water quality (Spearman rank value was 0.69). The decision-makers (Mozambique Government) must strengthen the prevention measures related to pathogens reduction in lettuce (i.e., washing) and engage in wastewater treatment engineering. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=annual%20infections%20risk" title="annual infections risk">annual infections risk</a>, <a href="https://publications.waset.org/abstracts/search?q=lettuce" title=" lettuce"> lettuce</a>, <a href="https://publications.waset.org/abstracts/search?q=non-parametric%20bootstrapping" title=" non-parametric bootstrapping"> non-parametric bootstrapping</a>, <a href="https://publications.waset.org/abstracts/search?q=quantitative%20microbial%20risk%20assessment%20tools" title=" quantitative microbial risk assessment tools"> quantitative microbial risk assessment tools</a> </p> <a href="https://publications.waset.org/abstracts/123837/the-use-of-non-parametric-bootstrap-in-computing-of-microbial-risk-assessment-from-lettuce-consumption-irrigated-with-contaminated-water-by-sanitary-sewage-in-infulene-valley" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123837.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">120</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Parasitic Infection among Farmers Dealing with Treated Wastewater in Al-Zaitoun Area, Gaza City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haneen%20Nabil%20Al-Sbaihi">Haneen Nabil Al-Sbaihi</a>, <a href="https://publications.waset.org/abstracts/search?q=Adnan%20Al-Hindi"> Adnan Al-Hindi</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Qahman"> Khalid Qahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Treated wastewater irrigation is associated with several benefits but can also lead to significant health risks. The main objective of this study is to investigate the parasitic infection (PI) among farmers dealing with treated wastewater (TWW) in Al-Zaitoun area- Gaza City. This study included two farmer groups: farmers who dealing with TWW (Mixed water users (MWUs)), and farmers who irrigate by using groundwater (GW) (Ground water users (GWUs)). Each participant was asked to provide stool samples on two phases. The two farmer groups were use GW in the 1st phase while the MWUs were use TWW in the 2nd phase which was after using TWW in irrigation for three months. Prevalence of PI was 30.9% and increased to be 47.3% in the 2nd phase. Negative association not statistically significant (OR= 0.659, CI 0.202-2.153)) was found in the 1st phase, while a positive association not statically significant was found between PI and TWWR in the 2nd phase (OR=1.37, CI 0.448-4.21). In this study six parasites species were identified among participants: Entamoeba ''histolytica/dispar and coil'', Cryptosporidium, Microsporidia, Giardia lamblia, Strongyloides stercoralis, and Ascaris lumbricoides. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wastewater" title="wastewater">wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater" title=" groundwater"> groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=treated%20wastewater" title=" treated wastewater"> treated wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=parasitic%20infection" title=" parasitic infection"> parasitic infection</a>, <a href="https://publications.waset.org/abstracts/search?q=parasites" title=" parasites"> parasites</a> </p> <a href="https://publications.waset.org/abstracts/153975/parasitic-infection-among-farmers-dealing-with-treated-wastewater-in-al-zaitoun-area-gaza-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153975.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Survey and Identification of Coinfecting Botryosphaeriales Causing Stem Canker Diseases of Eucalyptus camaldulensis in Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wendu%20Admasu">Wendu Admasu</a>, <a href="https://publications.waset.org/abstracts/search?q=Assefa%20Sintayehu"> Assefa Sintayehu</a>, <a href="https://publications.waset.org/abstracts/search?q=Alemu%20Gezahgne"> Alemu Gezahgne</a>, <a href="https://publications.waset.org/abstracts/search?q=Zewdu%20Terefework"> Zewdu Terefework</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Eucalyptus is the most widely planted forest tree species in the world. In Ethiopia, pathogenic fungi pose an increasing threat to Eucalyptus species. Due to limited research, there is insufficient information on the associated diseases and pathogens. This study investigated Eucalyptus diseases, the extent of their damage, and the causal fungal pathogens. A Eucalyptus disease survey was conducted in the Eucalyptus forestry areas of Ethiopia during the growth years 2019/20 and 2020/21. Disease assessment and sampling were carried out in eighteen plantations at nine locations. E. camaldulensis was the most dominant species planted in the surveyed areas. The field study shows a high incidence and severity of canker diseases. Diseased stem and branch samples were collected, cultured on malt extract agar media and studied. The results of morphological and ITS sequence analysis confirmed that the fungal species Neofusicoccum parvum, Lasiodiplodia theobromae, and Aplosporella hesperidica caused the observed canker symptoms. This is the first report of Lasiodiplodia theobromae and Aplosporella hesperidica causing diseases in Eucalyptus plants in Ethiopia. Changes in global climate and environmental factors, such as altitude, are believed to have a strong impact on the susceptibility of Eucalyptus plants to diseases. Strict quarantine practices and continuous monitoring of pathogenic and endophytic fungal species associated with Eucalyptus trees are issued to be prioritized to effectively control and manage the disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neofusicoccum" title="Neofusicoccum">Neofusicoccum</a>, <a href="https://publications.waset.org/abstracts/search?q=Lasiodiplodia" title=" Lasiodiplodia"> Lasiodiplodia</a>, <a href="https://publications.waset.org/abstracts/search?q=Aplosporella" title=" Aplosporella"> Aplosporella</a>, <a href="https://publications.waset.org/abstracts/search?q=pathogenicity" title=" pathogenicity"> pathogenicity</a>, <a href="https://publications.waset.org/abstracts/search?q=phylogeny" title=" phylogeny"> phylogeny</a>, <a href="https://publications.waset.org/abstracts/search?q=severity" title=" severity"> severity</a> </p> <a href="https://publications.waset.org/abstracts/179366/survey-and-identification-of-coinfecting-botryosphaeriales-causing-stem-canker-diseases-of-eucalyptus-camaldulensis-in-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179366.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">69</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Survey on Prevalence of Endo and Ecto-Parasites of Rattus rattus in Mazandaran Province, North of Iran </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Rezaei">Fatemeh Rezaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Afsaneh%20Amouei"> Afsaneh Amouei</a>, <a href="https://publications.waset.org/abstracts/search?q=Iman%20Bakouei"> Iman Bakouei</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Sharif"> Mahdi Sharif</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahabeddin%20Sarvi"> Shahabeddin Sarvi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Taghi%20Rahimi"> Mohammad Taghi Rahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Daryani"> Ahmad Daryani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Rodents act as reservoir host and important potential source for many zoonotic pathogens which pose a public health risk to humans. Therefore, it is necessary to investigate the prevalence of gastrointestinal and ectoparasites among rodents. Materials and Methods: 118 Rattus rattus were captured using snap live traps. Each rat was combed with a fine tooth comb to dislodge ectoparasite and studied. Various samples were collected from feces, examined wet smear, formalin-ether method and stained with modified acid-fast staining and trichrome. Result: The overall prevalence of gastrointestinal parasites of examined rats was 75.4%. Cryptosporidium 30.5%, was the most prevalent protozoan which was followed by Giardia 20.3% and Entamoeba muris 13.5%, Trichomonas muris 10.1% and Spironucleus muris 3.3%. The prevalence of helminth egg was as following Syphacia obvelata 24.5%, Hymenolepis diminuta 10.1% and Trichuris muris 9.3%. 86.4% rodents were found to be infested with ectoparasites including mite 35.6%, flea 28.4%, and lice 42.7%. A significant statistical difference was observed between prevalence and gender of infected individuals. Conclusions: The prevalence of gastrointestinal and ectoparasites of collected rats in studied area is remarkably high. In addition, Rattus rattus can be considered as potential risk for human health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prevalence" title="prevalence">prevalence</a>, <a href="https://publications.waset.org/abstracts/search?q=rodent" title=" rodent"> rodent</a>, <a href="https://publications.waset.org/abstracts/search?q=intestinal%20parasites" title=" intestinal parasites"> intestinal parasites</a>, <a href="https://publications.waset.org/abstracts/search?q=ecto-parasites" title=" ecto-parasites"> ecto-parasites</a>, <a href="https://publications.waset.org/abstracts/search?q=zoonose" title=" zoonose"> zoonose</a> </p> <a href="https://publications.waset.org/abstracts/55033/survey-on-prevalence-of-endo-and-ecto-parasites-of-rattus-rattus-in-mazandaran-province-north-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55033.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">532</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Intestinal Parasites Detected by Fecal Examination in Cats in the Konya Province, Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nermin%20Isik">Nermin Isik</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozlem%20Derinbay%20Ekici"> Ozlem Derinbay Ekici</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The cat is one of the potential hosts for parasitic zoonoses, such as Toxocara cati, Ancylostoma braziliense, A. tubaeforme, Uncinaria stenocephala, Cryptosporidium sp, Giardia sp. This study was performed to determine the prevalence and intensity of intestinal parasites in household cats in Konya, Turkey. In this study, a total of 100 stool samples with different ages and sex were used as a material. They were examined for infections with endoparasites by the use of native, Fulleborn flotation and Benedek sedimentation methods in University of Selcuk, Faculty of Veterinary Medicine, Department of Parasitology. The overall prevalence of intestinal parasites was 15%. A total of 6 parasite species was recorded: Giardia sp (6%), Toxocara cati (4%), Isospora sp (3%), Joyeuxiella pasqualei, Taenia sp (1%), Trichuris sp (1%). The most common intestinal parasites in cats were Giardia sp (6%) and Toxocara cati (4%). Younger cats up to 1 year of age were more frequently infected with endoparasites than animals over 1 year of age (p < 0.05). Giardia sp and Toxocara cati were detected significantly more often in younger than 1 year of age (p < 0.05). In fecal examination, Toxocara cati, Ancylostoma sp. Joyeuxiella pasqualei, Dipylidium caninum, Trichuris sp were found in cats in Turkey. In this study, based on microscopic and macroscopic fecal examinations, Giardia sp (6%), Toxocara cati (4%), Isospora sp (3%), Joyeuxiella pasqualei (%2), Taenia sp (1%), Trichuris sp (1%) was detected in cats. In conclusion, zoonotic intestinal parasites in household cats such as Giardia sp and Toxocara cati should be considered more seriously and it is necessary to take precautions against these infections. Cats should be routinely checked by faecal examination for endoparasite infections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cat" title="cat">cat</a>, <a href="https://publications.waset.org/abstracts/search?q=intestinal%20parasites" title=" intestinal parasites"> intestinal parasites</a>, <a href="https://publications.waset.org/abstracts/search?q=faecal" title=" faecal"> faecal</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkey" title=" Turkey"> Turkey</a> </p> <a href="https://publications.waset.org/abstracts/50937/intestinal-parasites-detected-by-fecal-examination-in-cats-in-the-konya-province-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50937.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">412</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Inactivation of Root-Knot Nematode Eggs Meloidogyne enterolobii in Irrigation Water Treated with Ozone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20A.%20Landa-Fernandez">I.

Currently, Meloidogyne enterolobii has increased its importance due to its high aggressiveness, increasing geographical distribution and host range. Root-knot nematodes inhabit the rhizosphere soil around plant roots. However, they can come into contact with irrigation water. Thus, plant-parasitic nematodes can be transported by water, as eggs or juveniles. Due to their high resistance, common water disinfection methods are not effective for inactivating these parasites. Ozone is the most effective disinfectant for microbial inactivation. The objective of this study is to demonstrate that ozone treatment is an alternative method control in irrigation water of the root-knot nematode M. enterolobii. It has been shown that ozonation is an effective treatment for the inactivation of protozoan cysts and oocysts (Giardia and Cryptosporidium) and for other species of the genus Meloidogyne (M. incognita), but not for the enterolobii specie. In this study, the strain of M. enterolobii was isolated from tomatoes roots. For the tests, eggs were used and were inoculated in water with similar characteristics of irrigation water. Subsequently, the disinfection process was carried out in an ozonation unit. The performance of the treatments was evaluated through the egg's viability by assessing its structure by optical microscopy. As a result of exposure to ozone, the viability of the nematode eggs was reduced practically in its entirety; with dissolved ozone levels in water close to the standard concentration (equal to 0.4 mgO₃/L), but with high contact times (greater than 4 min): 0.2 mgO₃/L for 15 minutes or 0.55 mgO₃/L for 10 minutes. Additionally, the effect of temperature, alkalinity and organic matter of the water was evaluated. Ozonation is effective and a promising alternative for the inactivation of nematodes in irrigation water, which could contribute to diminish the agricultural losses caused by these organisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inactivation%20process" title="inactivation process">inactivation process</a>, <a href="https://publications.waset.org/abstracts/search?q=irrigation%20water%20treatment" title=" irrigation water treatment"> irrigation water treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=ozonation" title=" ozonation"> ozonation</a>, <a href="https://publications.waset.org/abstracts/search?q=plant-parasite%20nematodes" title=" plant-parasite nematodes"> plant-parasite nematodes</a> </p> <a href="https://publications.waset.org/abstracts/92871/inactivation-of-root-knot-nematode-eggs-meloidogyne-enterolobii-in-irrigation-water-treated-with-ozone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92871.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">167</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Seasonal Prevalence of Gastrointestinal Parasites and Their Association with Trace Element Contents in Sera of Sheep, Grazing Forages and Soils of Sialkot District, Punjab, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hafiz%20M.%20Rizwan">Hafiz M.

Different types of forages are rich in trace element contents and may act as a natural resource to improve the trace element deficiencies leading to immunity boost-up in general and against gastrointestinal parasitic infections in particular. In the present study, the level of trace elements (Cu, Co, Mn, Zn) determined in sera of different breeds of sheep, available feedstuffs, respective soil samples and their association with GI helminths in Sialkot district, Punjab, Pakistan. Almost similar prevalence of GI helminths was recorded (32.81%) during spring 2015 and (32.55%) during autumn 2014. The parasitic species identified from the microscopically scanned faecal samples of district Sialkot were Fasciola (F.) hepatica, F. gigantica, Haemonchus contortus, Eimeria crandallis, Gongylonema pulchrum, Oesophagostomum sp., Trichuris ovis, Strongyles sp., Cryptosporidium sp. and Trichostrongylus sp. Among variables like age, sex, and breed, only sex was found significant in district Sialkot. A significant (P < 0.05) variation in the concentration of Zn, Cu, Mn, and Co was recorded in collected forages species. Soils of grazing field showed insignificant (P > 0.05) variation among soils of different tehsils of Sialkot district. Statistically, sera of sheep showed no variation (P > 0.05) during autumn 2014, While, variation (P < 0.05) among different tehsils of Sialkot district during spring 2015 except Co. During autumn 2014 the mean concentration of Cu, Zn, and Co in sera was inversely proportional to the mean EPG of sheep while during spring 2015 only Zn was inversely proportional to the mean EPG of sheep. The trace element-rich forages preferably Zn were effective ones against helminths infection. The trace element-rich forages will be recommended for their utilization as an alternate to improve the trace element deficiencies in sheep which ultimately boost up the immunity against gastrointestinal parasitic infections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coprological%20examination" title="coprological examination">coprological examination</a>, <a href="https://publications.waset.org/abstracts/search?q=gastro-intestinal%20parasites" title=" gastro-intestinal parasites"> gastro-intestinal parasites</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence" title=" prevalence"> prevalence</a>, <a href="https://publications.waset.org/abstracts/search?q=sheep" title=" sheep"> sheep</a>, <a href="https://publications.waset.org/abstracts/search?q=trace%20elements" title=" trace elements"> trace elements</a> </p> <a href="https://publications.waset.org/abstracts/69571/seasonal-prevalence-of-gastrointestinal-parasites-and-their-association-with-trace-element-contents-in-sera-of-sheep-grazing-forages-and-soils-of-sialkot-district-punjab-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69571.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">345</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Mechanical Transmission of Parasites by Cockroaches’ Collected from Urban Environment of Lahore, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hafsa%20Memona">Hafsa Memona</a>, <a href="https://publications.waset.org/abstracts/search?q=Farkhanda%20Manzoor"> Farkhanda Manzoor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cockroaches are termed as medically important pests because of their wide distribution in human habitation including houses, hospitals, food industries and kitchens. They may harbor multiple drug resistant pathogenic bacteria and protozoan parasites on their external surfaces, disseminate on human food and cause serious diseases and allergies to human. Hence, they are regarded as mechanical vector in human habitation due to their nocturnal activity and nutritional behavior. Viable eggs and dormant cysts of parasites can hitch a ride on cockroaches. Ova and cysts of parasitic organism may settle into the crevices and cracks between thorax and head. There are so many fissures and clefts and crannies on a cockroach which provide site for these organisms. This study aimed with identifying role of cockroaches in mechanically transmitting and disseminating gastrointestinal parasites in two environmental settings; hospitals and houses in urban area of Lahore. Totally, 250 adult cockroaches were collected from houses and hospitals by sticky traps and food baited traps and screened for parasitic load. All cockroaches were captured during their feeding time in natural habitat. Direct wet smear, 1% lugols iodine and modified acid-fast bacilli staining were used to identify the parasites from the body surfaces of cockroaches. Among human habitation two common species of cockroaches were collected i.e. P. americana and B. germanica. The results showed that 112 (46.8%) cockroaches harbored at least one human intestinal parasite on their body surfaces. The cockroaches from hospital environment harboured more parasites than houses. 47 (33.57%) cockroaches from houses and 65 (59.09%) from hospitals were infected with parasitic organisms. Of these, 76 (67.85%) were parasitic protozoans and 36(32.15%) were pathogenic and non-pathogenic intestinal parasites. P. americana harboured more parasites as compared to B. germanica in both environment. Most common human intestinal parasites found on cockroaches include ova of Ascaris lumbricoides (giant roundworm), Trichuris trichura (whipworm), Anchylostoma deodunalae (hookworm), Enterobius vermicularis (pinworm), Taenia spp. and Strongyloides stercoralis (threadworm). The cysts of protozoans’ parasites including Balantidium coli, Entomoeba hystolitica, C. parvum, Isospora belli, Giardia duodenalis and C. cayetenensis were isolated and identified from cockroaches. Both experimental sites were significantly different in carriage of parasitic load on cockroaches. Difference in the hygienic condition of the environments, including human excrement disposal, variable habitat interacted, indoor and outdoor species, may account for the observed variation in the parasitic carriage rate of cockroaches among different experimental site. Thus a finding of this study is that Cockroaches are uniformly distributed in human habitation and act as a mechanical vector of pathogenic parasites that cause common illness such as diarrhea and bowel disorders. This fact contributes to epidemiological chain therefore control of cockroaches will significantly lessen the prevalence of illness in human. Effective control strategies will reduce the public health burden of the gastro-intestinal parasites in the developing countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cockroaches" title="cockroaches">cockroaches</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20risks" title=" health risks"> health risks</a>, <a href="https://publications.waset.org/abstracts/search?q=hospitals" title=" hospitals"> hospitals</a>, <a href="https://publications.waset.org/abstracts/search?q=houses" title=" houses"> houses</a>, <a href="https://publications.waset.org/abstracts/search?q=parasites" title=" parasites"> parasites</a>, <a href="https://publications.waset.org/abstracts/search?q=protozoans" title=" protozoans"> protozoans</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission" title=" transmission"> transmission</a> </p> <a href="https://publications.waset.org/abstracts/43536/mechanical-transmission-of-parasites-by-cockroaches-collected-from-urban-environment-of-lahore-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43536.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">281</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Assessment of Current and Future Opportunities of Chemical and Biological Surveillance of Wastewater for Human Health</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adam%20Gushgari">Adam Gushgari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The SARS-CoV-2 pandemic has catalyzed the rapid adoption of wastewater-based epidemiology (WBE) methodologies both domestically and internationally. To support the rapid scale-up of pandemic-response wastewater surveillance systems, multiple federal agencies (i.e. US CDC), non-government organizations (i.e. Water Environment Federation), and private charities (i.e. Bill and Melinda Gates Foundation) have funded over $220 million USD supporting development and expanding equitable access of surveillance methods. Funds were primarily distributed directly to municipalities under the CARES Act (90.6%), followed by academic projects (7.6%), and initiatives developed by private companies (1.8%). In addition to federal funding for wastewater monitoring primarily conducted at wastewater treatment plants, state/local governments and private companies have leveraged wastewater sampling to obtain health and lifestyle data on student, prison inmate, and employee populations. We explore the viable paths for expansion of the WBE m1ethodology across a variety of analytical methods; the development of WBE-specific samplers and real-time wastewater sensors; and their application to various governments and private sector industries. Considerable investment in, and public acceptance of WBE suggests the methodology will be applied to other future notifiable diseases and health risks. Early research suggests that WBE methods can be applied to a host of additional “biological insults” including communicable diseases and pathogens, such as influenza, Cryptosporidium, Giardia, mycotoxin exposure, hepatitis, dengue, West Nile, Zika, and yellow fever. Interest in chemical insults is also likely, providing community health and lifestyle data on narcotics consumption, use of pharmaceutical and personal care products (PPCP), PFAS and hazardous chemical exposure, and microplastic exposure. Successful application of WBE to monitor analytes correlated with carcinogen exposure, community stress prevalence, and dietary indicators has also been shown. Additionally, technology developments of in situ wastewater sensors, WBE-specific wastewater samplers, and integration of artificial intelligence will drastically change the landscape of WBE through the development of “smart sewer” networks. The rapid expansion of the WBE field is creating significant business opportunities for professionals across the scientific, engineering, and technology industries ultimately focused on community health improvement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wastewater%20surveillance" title="wastewater surveillance">wastewater surveillance</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater-based%20epidemiology" title=" wastewater-based epidemiology"> wastewater-based epidemiology</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20cities" title=" smart cities"> smart cities</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20health" title=" public health"> public health</a>, <a href="https://publications.waset.org/abstracts/search?q=pandemic%20management" title=" pandemic management"> pandemic management</a>, <a href="https://publications.waset.org/abstracts/search?q=substance%20abuse" title=" substance abuse"> substance abuse</a> </p> <a href="https://publications.waset.org/abstracts/170289/assessment-of-current-and-future-opportunities-of-chemical-and-biological-surveillance-of-wastewater-for-human-health" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170289.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">108</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Awareness Creation of Benefits of Antitrypsin-Free Nutraceutical Biopowder for Increasing Human Serum Albumin Synthesis as Possible Adjunct for Management of MDRTB or MDRTB-HIV Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vincent%20Oghenekevbe%20Olughor">Vincent Oghenekevbe Olughor</a>, <a href="https://publications.waset.org/abstracts/search?q=Olusoji%20Mayowa%20Ige"> Olusoji Mayowa Ige</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Except for a preexisting liver disease and malnutrition, there are no predilections for low serum albumin (SA) levels in humans. At normal reference levels (4.0-6.0g/dl) SA is a universal marker for mortality and morbidity risks assessments where depletion by 1.0g/dl increases mortality risk by 137% and morbidity by 89%.It has 40 known functions contributing significantly to the sustenance of human life. A depletion in SA to <2.2g/dl, in most clinical settings worldwide, leads to loss of oncotic pressure of blood causing clinical manifestations of bipedal Oedema, in which the patients remain conscious. SA also contributes significantly to buffering of blood to a life-sustaining pH of 7.35-7.45. A drop in blood pH to <6.9 will lead to instant coma and death, which can occur after SA continues to deplete after manifestations of bipedal Oedema. In an intervention study conducted in 2014 following the discovery that “SA is depleted during malaria fever”, a Nutraceutical formulated for use as treatment adjunct to prevent SA depletions during malaria to <2.4g/dl after Efficacy testing was found to be satisfactory. There are five known types of Malaria caused by Apicomplexan parasites, Plasmodium: the most lethal being that caused by Plasmodium falciparum causing malignant tertian malaria, in which the fever was occurring every 48 hours coincides with the dumping of malaria-toxins (Hemozoin) into blood, causing contamination: blood must remain sterile. Other Apicomplexan parasites, Toxoplasma and Cryptosporidium, are opportunistic infections of HIV. Separate studies showed SA depletions in MDRTB (multidrug resistant TB), and MDRTB-HIV patients by the same mechanism discovered with malaria and such depletions will be further complicated whenever Apicomplexan parasitic infections co-exist. Both Apicomplexan parasites and the TB parasite belong to the Obligate-group of Parasites, which are parasites that replicate only inside its host; and most of them have capacities to over-consume host nutrients during parasitaemia. In MDRTB patients the body attempts repeatedly to prevent depletions in SA to critical levels in the presence of adequate nutrients and only for a while in MDRTB-HIV patients. These groups of patients will, therefore, benefit from the already tested Nutraceutical in malaria patients. The Nutraceutical bio-Powder was formulated (to BP 1988 specification) from twelve nature-based food-grade nutrients containing all dedicated nutrients for ensuring improved synthesis of Albumin by the liver. The Nutraceutical was administered daily for 38±2days in 23 children, in a prospective phase-2 clinical trial, and its impact on body weight and core blood parameters were documented at the start and end of efficacy testing period. Sixteen children who did not experience malaria-induced depletions of SA had significant SA increase; seven children who experienced malaria-induced depletions of SA had insignificant SA decrease. The Packed Cell Volume Percentage (PCV %), a measure of the Oxygen carrying capacity of blood and the amount of nutrients the body can absorb, increased in both groups. The total serum proteins (SA+ Globulins) increased or decreased within the continuum of normal. In conclusion, MDRTB and MDRTB-HIV patients will benefit from a variant of this Nutraceutical when used as treatment adjunct. <p class="card-text"><strong>Keywords:</strong> <a
