Culturing, Characterization And Identification Of Candidate Microorganisms In Cattle Ear, Responsible For Producing Volatile Constituents Attractive To The Brown Ear Tick

East Coast Fever is a disease of cattle which results in high animal mortality with corresponding economic losses to farmers and to the nation. The disease is caused by a protozoan agent whose vector is Rhipicephalus appendiculatus (Brown Ear Tick). The tick feeds dominantly inside the cattle ear. Studies have shown that the adults of R. appendiculatus exhibit „pull-push‟ effect that guides them to their preferred feeding site. This is linked to the presence of ear volatiles which attrac...

Effect Of Different Soil Fertility Amendments On The Nodulation And Yield Of Two Soybean Varieties

Soybean (Glycine max (L.) Merrill) is referred to as the golden crop of the future. There is a concern in Kenya on its production due to the fact that the country remains a net importer of this vital food to the tune of 100,000 tons annually yet the country has the potential to produce that capacity locally. The major impediments in local production are singled out as: Expensive farm inputs in form of fertilizers and use of inferior soybean varieties in terms of effective nodulation. The nodu...

Symbiotic Efficiency And Diversity Of Native Rhizobia Isolated From Climbing Beans (Phaseolus Vulgaris L.) In Embu And Tharaka Nithi Counties, Kenya

Kenya is the eighth highest producer of common beans (Phaseolus vulgaris L.) worldwide with a production of 529,265 tons annually. Climbing beans are highly productive, and can produce yields 2 to 3 times higher than bush beans and is therefore a promising option to increase bean yields in Kenya. However, climbing bean production is greatly affected by the decline in soil fertility, particularly low nitrogen levels in the soil. Replenishment of soil nitrogen using effective rhizobia inoculant...

Evaluation Of Genetic Diversity, Drug Resistance Mutational And Cytokine Patterns On Hepatotoxicity Markers Among Hiv Patients In Northwest Region, Cameroon
