Seroprevalence of Brucella spp. and Rift Valley fever virus among slaughterhouse workers in Isiolo County, northern Kenya
(UoEm, 2023-10-05)Brucella spp. and Rift Valley fever virus (RVFV) are classified as priority zoonotic agents in Kenya, based on their public health and socioeconomic impact on the country. Data on the pathogen-specific and co-exposure ... -
Seroprevalence of foot-and-mouth disease virus in cattle herds raised in Maasai Mara ecosystem in Kenya
(Elsevier, 2020-03)A cross-sectional study was carried out to determine foot-and-mouth disease (FMD) seroprevalence and identify risk factors of exposure among cattle herds raised in three zones with different types of land use and ... -
Short communication: Efficacy of two commercial disinfectants on Paenibacillus larvae spores
(2021-03)Paenibacillus larvae is a spore-forming bacterium causing American foulbrood (AFB) in honey bee larvae. The remains of a diseased larva contains billions of extremely resilient P. larvae spores viable for decades. Burning ... -

solation and characterization of naphthalene utilising bacteria from Nairobi River
(2006)Bacteria that utilise naphthalene were isolated on minimal medium from 3 sites along the Nairobi River. Sixteen isolates were obtained, characterised and identified as Listeria sp., Aerococcus viridans, Streptococcus ... -
Sorghum production for food security: A socioeconomic analysis of sorghum production in Nakuru County, Kenya
(Academic Journals, 2013-12-05)Kenya’s Vision 2030 identifies agriculture as one of the key sectors to deliver sustainable economic growth and improved livelihoods for the poor in the rural areas. However, the sector continues to face several endemic ... -
Spatial population dynamics of a specialist aphid parasitoid, Lysiphlebus hirticornis Mackauer (Hymenoptera: Braconidae: Aphidiinae): evidence for philopatry and restricted dispersal
(Macmillan Publishers Limited, 2010-01)Within insect communities, the population ecology of organisms representing higher trophic levels, for example, hymenopterous parasitoids, may be influenced by the structure of their insect hosts. Using microsatellite ... -

Species composition, abundance and fishing methods of small-scale fisheries in the seagrass meadows of Gazi Bay, Kenya
(Routledge, 2019-05)Fisheries are important sources of livelihoods to coastal communities. In the tropics fishing is conducted from mangroves, seagrass meadows to coral reefs. Studies on fisheries in the tropics have focused on coral reef ... -
Stay at home aphids: comparative spatial and seasonal metapopulation structure and dynamics of two specialist tansy aphid species studied using microsatellite markers
(The Linnean Society of London, 2011-06)Two tansy-feeding aphids, Macrosiphoniella tanacetaria (MA) and Metopeurum fuscoviride (ME), were studied at a small spatial scale in and around Jena (< 80 km2) using polymorphic microsatellite markers. Both species were ... -

STIP1/HOP Regulates the Actin Cytoskeleton through Interactions with Actin and Changes in Actin-Binding Proteins Cofilin and Profilin
(MDPI, 2020-04)Cell migration plays a vital role in both health and disease. It is driven by reorganization of the actin cytoskeleton, which is regulated by actin-binding proteins cofilin and profilin. Stress-inducible phosphoprotein ... -
A survey of root knot nematodes and resistance to Meloidogyne incognita in sweet potato varieties from Kenyan fields
(Elsevier, 2016-11)The root knot nematode, Meloidogyne is one of the most economically damaging plant parasitic nematode groups, and are widely distributed in Kenyan agro-ecosystems. The aim of this study was to determine the diversity of ... -
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 ... -
Temporal changes in phytoplankton structure and composition at the Turkwel Gorge Reservoir, Kenya
(Kluwer Academic Publishers, 1998)Temporal changes in phytoplankton chlorophyll a, composition, diversity, biomass (density and fresh weight) and primary production were investigated at the Turkwel Gorge Reservoir (Kenya) over a two year period (1994 and ... -
Temporal genetic structuring of a specialist parasitoid, Lysiphlebus hirticornis Mackauer (Hymenoptera: Braconidae) attacking a specialist aphid on tansy
(2010-11)In insect species characterized by inbreeding, limited dispersal, and a metapopulation structure, high genetic differentiation and reduced genetic diversity within local populations are expected. Using the model ... -
