Genetic Diversity And Viral Disease Resistance Of The Indigenous Chickens From Selected Areas In Kenya

ABSTRACTIndigenous chickens show extensive physical diversity. However, industrialization and globalization of chicken in the 21st century has affected and limited their genetic resources to industrial breeds. Continuous selection for rapid growth and more egg production has resulted in the loss of disease resistance and overall immuno-competence hence a projected increase in disease-related costs in the future. Genetic control of disease resistance is one of the most important targets of bre...

Genetic Characterization Of Honeybee (Apis Mellifera) In Como-Ros Islands Using Mitochondrial And Microsatellite Mark-Ers

ABSTRACTHoneybees, Apis mellifera, are key contributors to the global economy, nutrition, food security and ecological biodiversity. Despite their robust benefits, declines in honeybee populations have been reported owing to a number of factors. Such include pests and diseases, climate change, poor management practices, change in land usage and low ge-netic diversity. High intra-colonial genetic diversity is associated with resilience and re-sistance to pest and diseases as well as increased ...

Bioengineering Tomato (Solanum Lycopersicum Mill) With Peptide Aptamer For Meloidogyne Incognita Chorismate Mutase As A Strategy For Nematode Resistance

ABSTRACTRoot knot nematodes (RKNs) of (Meloidogyne spp.) are among the most devastating soil-borne plant parasitic pests infecting many food crops. They have been shown to result in over 50% loss of crop yield in tomato (Lycopersicon esculentum Mill). Various control measures including agronomic practices and nematicides have been employed in the past to manage the parasite with only modest gains. These are also costly to small-scale farmers especially in developing countries. There is need t...

Diversity, Symbiotic Efficiency And Effect Of Water Hyacinth Compost On Population Of Rhizobia Nodulating Phaseolus Vulgaris In Lake Victoria Basin.

ABSTRACTDespite having a lot of resources, Lake Victoria Basin has had an increase in population and land degradation and a reduction in agricultural production due to poor soil fertility. This has necessitated the use of inorganic fertilizers to boost food production. Inorganic fertilizers production contributes to emission of greenhouse gases. Use of inorganic fertilizer in Lake Victoria basin may have led to eutrophication of Lake Victoria leading to social, economic and ecological problem...

Comparison Of Analytical Profile Index, Microscan Walkaway 40 Plus And Bruker Maldi Biotyper Systems For Identification Of Enteric Pathogens In Kenya

ABSTRACTDeveloping countries experience diarrheal disease at a higher rate thanindustrialized nations. A key contributor to increased morbidity and mortalityfrom diarrheal disease is the lack of efficient diagnosis methods. In Kenyadiagnosis of enteric pathogens is mainly performed using manual methods whichinvolves colony morphology, gram stain and biochemical tests. Although thesemethods are generally reliable they are labour intensive, have a long turn-aroundtime and they occasionall...
