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 ... -
Development of cost-effective media for the culture of Chilo partellus larvicide in Kenya
(Academic Journals, 2013-03)Stem borers (Chilo partellus) are important field insect pests of maize (Zea mays L.) and sorghum (Sorghum bicolor L.) in Africa. They account for more than 30% yield losses depending on the composition of the pest community. ... -
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 ... -
Diallel analysis of Snap bean (Phaseolus vulgaris l.) varieties for important traits
(2010-08-04)The breeding programmes of many crops use diallel analyses because of the genetic information they offer to breeders. Six morphological and agronomic traits of Snap bean (Phaseolus vulgaris L.) were studied to investigate ... -
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, ... -
Disappearing medicinal plants in mt. kenya forests, kenya: a case study of east african green heart (Warburgia ugandensis sprague)
(2013-07)Natural disturbances and human activities are significantly affecting indigenous trees species in forests. Warburgia ugandensis is a plant highly valued for its medicinal properties, timber and fuel among other uses. Many ... -
Distribution of indigenous strains of atoxigenic and toxigenic Aspergillus flavus and Aspergillus parasiticus in maize and peanuts agro‑ecological zones of Kenya
(Springer (BioMed Central Ltd), 2015-09)Background Grains of important food and export crops in Africa are susceptible to contamination by toxin-producing moulds. Aflatoxins are mycotoxins associated with liver damage and cancer in humans and animals. These ... -
Diversity and Abundance Patterns of Amphibians in Rehabilitated Quarries of Bamburi Near Mombasa (Kenya)
(Research, 2013-11)Amphibians are sensitive to changes in the environment and are, therefore, excellent indicators of success in restoring degraded habitats. As such, a clear understanding on how amphibian populations respond to changes ... -
Diversity and structure of prokaryotic communities within organic and conventional farming systems in central highlands of Kenya
(PLOS, 2020-08)Management practices such as tillage, crop rotation, irrigation, organic and inorganic inputs application are known to influence diversity and function of soil microbial populations. In this study, we investigated the ... -
Diversity of esterase and lipase producing haloalkaliphilic bacteria from Lake Magadi in Kenya
(2019-09)Lipids are hydrocarbons comprised of long‐chain fatty acids and are found in all living things. In the environment, microorganisms degrade them to obtain energy using esterases and lipases. These enzymes are nowadays ... -
Diversity of fungi in sediments and water sampled from the hot springs of Lake Magadi and Little Magadi in Kenya
(2016-02)Lake Magadi and Little Magadi are saline, alkaline lakes lying in the southern part of Kenyan Rift Valley. Their solutes are supplied by a series of alkaline hot springs with temperatures as high as 86°C. Previous ... -
Diversity of Termitomyces Associated with Fungus- Farming Termites Assessed by Cultural and Culture- Independent Methods
(2013)Background: Fungus-cultivating termites make use of an obligate mutualism with fungi from the genus Termitomyces, which are acquired through either vertical transmission via reproductive alates or horizontally transmitted ... -
Do afroalpine plants differ from other alpine plants by their leaf functional traits?
(UoEm, 2023-06-16)Afroalpine plants develop under specific climate with great daily fluctuations and weak seasonal dynamics of temperature. Do leaf functional traits of the plants in Mt. Kenya differ from those of temperate plants in ... -
