Sero-epidemiological survey of Coxiella burnetii in livestock and humans in Tana River and Garissa counties in Kenya
(Plos, 2022-03)Background Coxiella burnetii is a widely distributed pathogen, but data on its epidemiology in livestock, and human populations remain scanty, especially in developing countries such as Kenya. We used the One Health ... -
Genetic Diversity and Population Structure of Doum Palm (Hyphaene compressa) Using Genotyping by Sequencing
(Frontiers, 2022-02)Doum palm (Hyphaene compressa) is a perennial economic plant primarily growing in Kenya’s Arid and Semi-Arid Lands (ASALs). It is heavily relied upon for food, animal feed, construction materials and medicine, making it ... -
Effect of supplemental feeding on habitat and crop selection by wild boar in Sweden
(Taylor & Francis, 2022-01)The wild boar population has increased rapidly during the last 2 decades in Southern and Central Sweden. This rise in population size has caused severe damages to agricultural fields through their foraging behavior. Given ... -
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 ... -
Land use effects on termite assemblages in Kenya
(Heliyon, 2021-12)Termites perform key ecological functions and they also cause crop damage. Land use change resulting from agricultural intensification can result in changes in termite species diversity and abundance. Termite species occurring ... -
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 ... -
Root and soil health management approaches for control of plant-parasitic nematodes in sub-Saharan Africa
(Elsevier, 2021-10)Smallholder farmers in sub-Saharan Africa (SSA) face several challenges that include pests and diseases. Plant-parasitic nematodes (PPN) reduce crop yields and affect their quality. They are an emerging threat to smallholder ... -
Seagrass Loss and Sub-Surface Carbon Fate: Insights from a Long-Term Experimental Removal in Gazi Bay, Kenya
(Jupiter Publishers, 2021-08)Seagrass meadows are considered as global hotspots of blue carbon stocks. However, they suffer global cover loss mainly due to anthropogenic activities. Few is known on the impact of seagrass loss on their blue carbon ... -
