The minimum inhibition concentrations (MIC) of the essential oils, were determined by turbidimetric technique using Biocreen C, analyzer. The effects of pH ranging from 7.3 to 5.5 in absence and presence of essential oils and/or NaCl on the lag time and mean generation time of the bacteria at 370C, were carried out and results were determined showed that, combination of low pH and essential oil at 370C had additive effects against the test micro-organisms. The combination of 1.2 % (w/v) of NaCl and clove essential oil at 0.0325% (v/v) was effective against E. coli. The use of concentrations less than MIC in combination with low pH and or NaCl has the potential of being used as an alternative to “traditional food preservatives".</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Antimicrobial" title="Antimicrobial">Antimicrobial</a>, <a href="https://publications.waset.org/search?q=Bacteria" title=" Bacteria"> Bacteria</a>, <a href="https://publications.waset.org/search?q=Bioscreen%20C" title=" Bioscreen C"> Bioscreen C</a>, <a href="https://publications.waset.org/search?q=essential%20oil." title=" essential oil."> essential oil.</a> </p> <a href="https://publications.waset.org/11623/the-effect-of-sodium-chloride-and-ph-on-the-antimicrobial-effectiveness-of-essential-oils-against-pathogenic-and-food-spoilage-bacteriaimplications-in-food-safety" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/11623/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/11623/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/11623/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/11623/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/11623/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/11623/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/11623/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/11623/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/11623/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/11623/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/11623.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">4862</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Development of All-male Fingerlings by Heat Treatment and the Genetic Mechanism of Heat Induced Sex Determination in Nile Tilapia(Oreochromis niloticus L.)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=P.%20O.%20Angienda">P.

Waindi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Juvenile Nile tilapia subjected to heat treatment at temperatures ranging from 260C to 370C showed positive correlation (P<0.01) between treatment temperatures and resultant sex ratios, while, survival rate of the fry showed a negative correlation against temperature (P<0.01). The optimal temperature for both sex shift towards males and survival rates was 36卤0.5掳C, producing male percentage of 86.31 and a fry survival of 65.25. To determine the genetic basis of temperature sex-determination in Nile tilapia, we employed three microsatellite markers (Abur36, Abur100 and UNH846). Abur36 predicted the sex of 95% of the heat induced individuals, suggesting that the locus influence sex ratio and its interaction with temperature result in male biased sex ratio. This locus could turn out to be the major sex determining gene operating in Nile tilapia. These markers could be used in marker-assisted selection to select genotypes that give a higher percentage of males for commercial production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Heat%20treatment" title="Heat treatment">Heat treatment</a>, <a href="https://publications.waset.org/search?q=Microsatellite" title=" Microsatellite"> Microsatellite</a>, <a href="https://publications.waset.org/search?q=Nile%20tilapia" title=" Nile tilapia"> Nile tilapia</a>, <a href="https://publications.waset.org/search?q=sex-determination." title=" sex-determination."> sex-determination.</a> </p> <a href="https://publications.waset.org/608/development-of-all-male-fingerlings-by-heat-treatment-and-the-genetic-mechanism-of-heat-induced-sex-determination-in-nile-tilapiaoreochromis-niloticus-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/608/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/608/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/608/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/608/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/608/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/608/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/608/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/608/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/608/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/608/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/608.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">3706</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Epidemiology of Waterborne Diarrhoeal Diseases among Children Aged 6-36 Months Old in Busia - Western Kenya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=D.%20M.%20Onyango">D.

Angienda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of the present study was to evaluate the epidemiology of waterborne diarrhoeal among children aged 6-36 months old in Busia town, western Kenya. The study was carried out between Feb. 2008 and Feb. 2010. Cases of diarrhoea reported in 385 households were linked to household water handling practices. A mother with a child of 6-36 months old was also included in the study. Diarrhoea prevalence among children 6-36 months was 16.7% in Busia town, Bwamani (19.6%) and Mayenje (10.6%) clustered in Mayenje sub-location reported the highest and the lowest prevalence of diarrhoea. There was a positive correlation between the prevalence of diarrhoea in children and the level of the mother-s education, 29.9% (n= 100). Diarrhoea cases decreased in range from 35.5% (n =102) to 4.8% (n= 16), corresponding to increase in age from 6-35 months on average. In conclusion, prevalence of diarrhoea in children of 6-36 months old was 16.7% in Busia town. This was higher in children whose mother-s age was below 18 years and with low level of education, the rate decreased with increase in age of children. Prevalence of diarrhoea in children aged 6-36months in households was higher in children aged 6-17 and 36 months and whose mothers were less educated and fell between the ages of 18-24 years. The Influence of human activities at the main source of drinking water on the prevalence of diarrhoea in these children was insignificant. <p class="card-text"><strong>Keywords:</strong> <a
