Identification and distribution of pathogens coinfecting with Brucella spp., Coxiella burnetii and Rift Valley fever virus in humans, livestock and wildlife
(Wiley, 2002-01)Zoonotic diseases, such as brucellosis, Q fever and Rift Valley fever (RVF) caused by Brucella spp., Coxiella burnetii and RVF virus, respectively, can have devastating effects on human, livestock, and wildlife health ... -
Identification of new sorghum genotypes resistant to the African and spotted Stem borers
(2014)Lepidopteran stemborers, mainly the African stemborer Busseola fusca Fuller and spotted stemborer Chilopartellus Swinhoe, are among the economically important pests of sorghum in Kenya. Identification of sources of resistance ... -
Impact of low-cost management techniques on population dynamics of plant-parasitic nematodes in sweet potato
(Elsevier, 2020-07)Sweet potato is an important food security crop but its production is limited by various biotic constraints including plant-parasitic nematodes (PPN). In Kenya, current PPN management practices in sweet potato have several ... -
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 ... -
In vitro anti-cancer efficacy and phyto-chemical screening of solvent extracts of Kigelia africana (Lam.) Benth
(Cell press, 2021-01-25)Background and objectives: Kigelia africana is a medicinal plant growing naturally in many parts of Africa. In Kenya, a water concoction of the plant is used to treat breast and prostate cancers. Laboratory data on its ... -
In vitro antiplasmodial activity of some plants used in Kisii, Kenya against Malaria and their chloroquine potentiative effects.
(2003)Fifty-five organic and aqueous extracts of 11 plants used in malaria therapy in Kisii District, Kenya were tested in vitro against chloroquine (CQ)-sensitive and resistant strains of Plasmodium falciparum. Of the plants ... -
In vivo antimalarial and acute toxicity properties of hexane and chloroform extracts from Clausena anisata (Willd.) Benth
(2012)Background: Drugs are an important tool for control of malaria. However, drug resistance is likely to compromise available antimalarial drugs with time. As a result, efforts are being directed towards discovery and development ... -
Incidence of Brucella infection in various livestock species raised under the pastoral production system in Isiolo County, Kenya
(BMC, 2021-10)Background: We implemented a longitudinal study to determine the incidence of Brucella infection in cattle, camels, sheep and goats that were being raised in a pastoral area in Isiolo County, Kenya. An initial cross-sectional ... -
Infestation Levels and Molecular Identifcation Based on Mitochondrial COI Barcode Region of Five Invasive Gelechiidae Pest Species in Kenya
(Oxford University Press, 2018-06)Invasive Gelechiidae pest species, namely Tuta absoluta, Phthorimaea operculella, Aproaerema simplixella, Sitotroga cerealella, and Pectinophora gossypiella are among the major constraints hampering agricultural economy ... -

The influence of diel climatic cycle on the depth time distribution of phytoplankton and photosynthesis in a shallow equatorial lake (Lake Baringo), Kenya.
(Springer, 1995-05)Lake Baringo is a shallow equatorial lake. This paper reports a diel study of the depth-time distribution of phytoplankton and photosynthesis at one location in Lake Baringo on 10 March 1989. The water column shows a pattern ... -
Influence of drought on interactions between Rhopalosiphum padi and ground dwelling predators – A mesocosm study
(Wiley, 2021-05)Climate change will lead to extreme droughts, but it is difficult to predict how this will affect crop pests. In particular, it is unclear how interactions between natural en- emies and pests will be influenced. In the ... -
Influence of large woody debris accumulations on macro invertebrate distribution in a low order forested tropical stream, Sagana river, Kenya
(Jomo Kenyatta University of Agriculture and Technology, 2014)Woody debris accumulations are important ecological components in low order forested streams. They provide forage and refuge for a macroinvertebrates, which are key trophic components for riverine fish. The occurrence ... -
INFLUENCE OF LARGE WOODY DEBRIS ACCUMULATIONS ON MACROINVERTEBRATE DISTRIBUTION IN A LOW ORDER FORESTED TROPICAL STREAM, SAGANA RIVER, KENYA
(Jomo Kenyatta University of Agriculture and Technology, 2014)Woody debris accumulations are important ecological components in low order forested streams. They provide forage and refuge for a macroinvertebrates, which are key trophic components for riverine fish. The occurrence ... -
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 ... -
International Journal of Environment and Climate Change
(2020-12-21)Africa is under pressure from climate stresses and is highly vulnerable to the impacts of climate change. In Kenya, agriculture is the backbone of the economy making it an important contributor to food security of rural ... -
Is leaf pubescence of Cape Proteaceae a xeromorphic or radiation-protective trait?
(CSIRO Publishing, 2012-03)Although pubescence has traditionally been considered to be related to the water economy of plants, the results are ambivalent and vary between different species. We tested two contrasting hypotheses for the functional ... -
Isolation and characterisation of bacteria from the haloalkaline Lake Elmenteita, Kenya
(Springer, 2010-04)Culture-independent studies show that soda lake environments harbour diverse groups of bacteria and archaea. In this study different enrichment and isolation media were used in an attempt to isolate novel groups of bacteria ... -
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 ... -
