Interaction of Fusarium oxysporum f.sp.vasinfectum and the fungal feeding nematode Aphelechus avenae on Bt cotton
(2014)The fungal feeding nematode Aphelenchus avenae (APH) feeds on different species of fungi including Fusarium oxysporum f. sp. vasinfectum (FOV) that causes wilt in cotton. The objective of this study was to assess the ... -
Evaluating diversity among Kenyan sweet potato genotypes using morphological and SSR markers
(2010)Genetic diversity of 89 sweet potato genotypes was evaluated using morphological and molecular markers. Eighteen aerial and sixteen storage root characters were used in the morphological characterization. Analysis of ... -
Effect of transgenic cotton expressing Cry1Ac and Cry2Ab2 protein on entomopathogenic nematodes, Steinernema karii and Heterorhabditis bacteriophora.
(2013)Entomopathogenic nematodes are used in biological control of pests. The cry proteins from insect resistant cotton may affect their infectivity. The effect of Bacillus thuringiensis (Bt) cotton (06Z604D) on infectivity of ... -
Effect of Bt cotton expressing Cry1Ac and Cry2Ab2 protein on soil nematode community assemblages in Mwea, Kenya
(2013)Objective: The nematode community structure in soil cultivated with Bt cotton (containing Cry1Ac and Cry2Ab2 protein), isoline (non Bt cotton) and HART 89M (non Bt cotton) was evaluated in a field trial at Ndomba in the ... -
Bandwidth selection in smoothing functions
(2006)A simple criterion for selecting a bandwidth parameter that controls the amount of smoothing in functions is described. The procedure is computationally inexpensive and, hence, worth adopting. We argue that the bandwidth ... -
Isolation, characterization and identification of Diazinon degrading bacteria from the soil and gut of macrotermes
(2013)Diazinon degrading bacteria were isolated from the soil and gut of fungus cultivating termites Macrotermes michaelseni using MM7 media supplemented with pesticide as the sole source of carbon and energy. The isolates were ... -
Isolation, characterization and identification of roundup degrading bacteria from the soil and gut of Macrotermes michaelseni
(INNSPUB, 2013-09-10)Roundup degrading bacteria were isolated from the soil and gut of fungus cultivating termites Macrotermes michaelseni using MM7 media supplemented with the pesticide as the sole source of carbon and energy. The isolates ... -
Isolation and characterization of actinobacteria from Lake Magadi, Kenya
(Academic Journals, 2013-08-09)Actinobacteria are ubiquitous and have been detected in terrestrial and aquatic ecosystems. Although, various studies have focused on the ecology of this phylum, data on the ecology of actinobacteria endemic to soda lakes ... -
Evaluation of an antigen-antibody “combination” enzyme linked immunosorbent assay for diagnosis
(2014-10)Background Development of “combination” assays detecting in parallel, within a single test, Hepatitis C Virus (HCV) antigens and antibodies, not only reduces the window period in HCV-infection but also costs. Reduction ... -
Effectiveness of antituberculosis treatment among patients receiving highly active antiretroviral therapy at Vihiga District Hospital in 2007
(2010)PURPOSE: In Kenya there is need for proper co-ordination of antiretroviral therapy (ART) and tuberculosis (TB) treatment as most (60%) of the TB patients are also human immunodeficiency virus (HIV) positive. This study ... -
Chemical properties associated with guts, soil and nest materials of Odontotermes and Macrotermes species from Kenya
(2010)Changes in carbon and nitrogen cycles in tropical soils affect soil functioning and ecosystem activity. Termites play important roles in carbon and nitrogen cycles, thus determination of levels of such compounds is essential. ... -
Strategic Organisation Development and Project Performance of Not for Profit Organisations’ In Isiolo Sub-County-Kenya
(2014-06)The study was conducted to establish the influence of strategic organization development strategies on the performance of not for profit organizations projects in Isiolo district. The study was developed from a problems ... -
Metal status of Nairobi riverwaters and their bioaccumulation in Labeo cylindricus
(Academic Journals, 2005-03)This study focused on the analysis of metals in water and fish from Nairobi River. Water from Kikuyu, Kawangware, Chiromo, Eastleigh, Njiru and Fourteen Falls along the Nairobi River was analyzed for the presence of metals. ... -
Laboratory surveillance of cholera in Nyanza Province
(2014)Cholera continues to be an important cause of morbidity and mortality in many areas of the world, and there is currently a high frequency of new outbreaks in Africa. Following a confirmed cholera outbreak in Siaya, Kisumu, ... -
Characterization of antibiotic resistance in environmental enteric pathogens from Kibera slum in Nairobi-Kenya
(Academic Journals, 2012-10)Kibera slum is characterized by poor sanitation hence the frequent outbreaks of diarrheal diseases. Emergence of antibiotic resistance by diarrhoea-causing bacteria is an inevitable challenge in the area. Diarrhea-causing ... -
Assessment of Risk Predisposition to Human Papilloma Virus through Cervical Infections Screening of Women Attending an Outpatient Health Facility In Nairobi, Kenya
(IISTE, 2014)There is limited data on comparative disposition to cervical cancer among HPV infected women in Kenya. We aimed to determine the distribution of HPV infection, cervical abnormalities and infections commonly reported on ... -
Antimicrobial activity of Warbugia ugandensis against gramnegative multi‐drug resistant bacteria
(Jomo Kenyatta University of Agriculture and Technology, 2014)The rise in antibiotic resistance has resulted in decreasing numbers of effective antimicrobial agents available to treat infections caused by multi‐drug resistant (MDR) bacteria. This has necessitated a search for new ... -
