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. ... -
Response of Selected Kenyan Rice Cultivars to Infection by Root Knot Nematode (Meloidogyne incognita)
(2019-03)Meloidogyne incognita causes huge yield losses in rice which is the third most important cereal crop in Kenya. The aim of this study was to identify M. incognita-resistant rice cultivars from Kenya and relate the responses ... -

The rise of potentially toxin producing cyanobacteria in Lake Naivasha, Great African Rift Valley, Kenya
(Elsevier, 2013-07)Lake Naivasha, an important inland water ecosystem and a crucial freshwater resource in the Great African Rift Valley, has displayed clear signals of degradation in recent decades. We studied the phytoplankton composition ... -
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 ... -
SARS-CoV-2 Molecular Clock and Zoonosis
(Academic Journals, 2020-06)SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2), associated with Corona Virus Disease 2019 (COVID-19) coined by World Health Organization, belongs to single stranded RNA viruses (ssRNA Viruses) under ... -
Screening for Water Deficit Tolerance, Relative Growth Analysis and Agrobacterium-Infectivity in Tropical Maize [Zea Mays L.] Inbred Lines in Nairobi, Kenya
(2014-12)The gap between maize demand and regional supply is increasing as small-holder farmers grapple with many challenges, key among them drought. Research in identifying maize lines that are tolerant to water deficit and that ... -
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 ... -
Seagrass Removal Leads to Rapid Changes in Fauna and Loss of Carbon
(Frontiers, 2019-03)Seagrass habitats are important natural carbon sinks, with an average of ∼14 kg C m−2 buried in their sediments. The fate of this carbon following seagrass removal or damage has major environmental implications but is ... -
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 ... -
Serological evidence of single and mixed infections of Rift Valley fever virus, Brucella spp. and Coxiella burnetii in dromedary camels in Kenya
(PLOS, 2021-03)Camels are increasingly becoming the livestock of choice for pastoralists reeling from effects of climate change in semi-arid and arid parts of Kenya. As the population of camels rises, better understanding of their role ... -
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 ... -
