Impregnated dry Filter paper as an Alternative medium for Transporting Diarrhoeal Stool Samples
(2008)Diarrhoea due to bacterial infections is a major cause of morbidity and mortality both in children and adults and hence lowers economic activity especially in developing countries. This is especially important in areas ... -
Expression of metallothionein and tubulin in heavy metal-tolerant Anopheles gambiae sensu stricto (Diptera:Culicidae).
(Elsevier, 2010)Anopheles mosquitoes have been shown to adapt to heavy metals in their natural habitats. In this study we explored the possibility of using Anopheles gambiae sensu stricto as bioreporters for environmental heavy metal ... -
Urinary Schistosomiasis in two family populations, using school children as tracers
(1988)Two groups of families designated A and B were studied for Schistosoma haematobium infection in Amagunze, Anambra State, Nigeria. The groups were selected on the basis of a preliminary screening of schoolchildren: group A ... -
Uncovering the tracks of a recent and rapid invasion: the case of the fruit fly pest Bactrocera invadens in Africa.
(Blackwell Publishing Ltd, 2009-09-10)Phytophagous insects of the genus Bactrocera are among the most economically important invasive fruit fly pests. In 2003, an unknown Bactrocera species was found in Kenya. First identified as an ‘aberrant form’ of the ... -
The Glossina proteolytic lectin (Gpl) gene is expressed only in members of Glossina species
(2008)Differentiation of bloodstream-form trypanosomes into procyclics in tsetse flies (Diptera: Glossinidae) is a crucial step in the establishment of midgut infections. A number of factors have been implicated in the ... -
The Glossina proteolytic lectin (Gpl) gene is expressed only in members of Glossina species
(2007-12)Differentiation of bloodstream-form trypanosomes into procyclics in tsetse flies (Diptera: Glossinidae) is a crucial step in the establishment of midgut infections. A number of factors have been implicated in the transformation ... -
The diagnostic value of haematuria and proteinuria in Schistosoma haematobium infection in Southern Nigeria.
(1992)Haematuria and proteinuria as detected by chemical reagent strips correlated moderately (r=0·7) with prevalence and intensity of infection with Schistosoma haematobium in an area of Anambra State, Nigeria. Differences ... -
Pathogenic Escherichia coli and food handlers in luxury hotels in Nairobi, Kenya
(Elsevier, 2009-05)Background: The epidemiology and virulence properties of pathogenic Escherichia coli among food handlers in tourist destination hotels in Kenya are largely uncharacterized. Method: This cross-sectional study among ... -
Differential Induction of Proteins in Anopheles gambiae sensu stricto (Diptera: Cullicidae) Larvae in Response to Heavy Metal Selection
(National Institute of Health, 2010-07-21)Investigations were conducted to establish the magnitude and pattern of differential expression of proteins due to generational selection of third instar An. gambiae s.s. larvae by cadmium, copper and lead heavy metals, ... -
Detection of trypanosomes in small ruminants and pigs in western Kenya: important reservoirs in the epidemiology of sleeping sickness?
(2005-07-14)Background: Trypanosomosis is a major impediment to livestock farming in sub-Saharan Africa and limits the full potential of agricultural development in the 36 countries where it is endemic. In man, sleeping sickness is ... -
Characterization of algae oil (oilgae) and its potential as biofuel in Kenya
(2012-05)A survey of microalgae biodiversity in three Kenyan Rift valley lakes identified high oil yielding species abundantly distributed naturally. The species were cultured in BBM and BG-11 media to obtain pure clones and lipids ... -
Biosafety education relevant to genetically engineered crops for academic and non-academic stakeholders in East Africa
(2009-01-15)Development and deployment of genetically engineered crops requires effective environmental and food safety assessment capacity. In-country expertise is needed to make locally appropriate decisions. In April 2007, biosafety ... -
Analysis of genetic diversity in Eucalyptus grandis (Hill ex Maiden) seed sources using inter simple sequence repeats (ISSR) molecular markers
(Academic Journals, 2008-07-04)Eucalyptus grandis is an economically important tree species that is native to the Australian continent and its northern neighbours, where it is grown primarily for its hard wood timber and pulp for paper industries. It ... -
A prototype parabolic trough solar concentrators for steam production
(Jomo Kenyatta University of Agriculture and Technology, 2012)In this work, the potential for a solar-thermal concentrator to produce steam has been studied. Three parabolic trough solar concentrators (PTSCs) of dimensions: - aperture width of 1.2 m, Collector length of 5.8 m and ... -
Investigating a Prototype Heat Exchanger for Steam Storage
(2014-07)A coiled tube single pass counter flow heat exchanger was designed and fabricated using locally available materials and its capacity to transmit heat to water to make steam was tested. The heat exchanger was part of ... -
A Prototype Steam Storage System for Power Production
(2014-08-01)Use of solar energy on a large scale is mainly limited to the sun duration hours, weather conditions and adequate solar thermal storage technology. A means of addressing this problem using local materials is provided. ... -
Survey of sweet potato viruses in Western Kenya and detection of cucumber mosaic virus.
(2010)Sweet potato is an important food crop worldwide, but several pests and diseases limit its production. In eastern Africa, virus-induced diseases rank second to weevils in causing yield reduction. Symptomatic sweet potato ... -
Reproduction of root knot nematode (Meloidogyne icognita) on Bt cotton expressing Cry1Ac and Cry2Ab2 protein.
(2013)Objective: The sedentary endoparasite Meloidogyne incognita is an important plant parasitic nematode that infects cotton causing significant yield losses. The objective of this study was to evaluate reproduction of M. ... -
Occurrence and distribution of soil nematodes in cotton production areas of Kenya.
(2010)A baseline survey was conducted to determine the occurrence and distribution of soil nematodes associated with cotton in major growing areas in Kenya. Such baseline data on soil nematode abundance, diversity and ecosystem ... -
Nematode diversity in soil from a field trial with decomposing Bt cotton expressing Cry1Ac and Cry2Ab2 protein
(2013)The quality of decomposing plant materials may affect the soil community structure. The aim of the study was to determine the impact of decomposing Bt cotton and its isoline on soil nematode diversity. Bt cotton (06Z604D), ...
