Most studies of infectious diseases in East African cattle have concentrated on gastro-intestinal parasites and vector-borne diseases. As a result, relatively little is known about viral diseases, except for those that are clinically symptomatic or which affect international trade such as foot an...

A study using participatory epidemiology (PE) methodologies was conducted in West Pokot and Baringo districts, Northern Rift Valley, Kenya to assess the status of East Coast Fever (ECF) and obtain livestock keepers’ perceptions of how the disease impacts on their livelihoods. A total of 658 live...

The Kenyan East African zebu cattle are valuable and widely used genetic resources. Previous studies using microsatellite loci revealed the complex history of these populations with the presence of taurine and zebu genetic backgrounds. Here, we estimate at genome-wide level the genetic compositio...


Mbole-Kariuki, Mary N.Sonstegard, T.S.Orth, AlanThumbi, S.M.Bronsvoort, B.M. de C.Kiara, Henry K.Toye, Philip G.Conradie, I.Jennings, A.Coetzer, K.Woolhouse, Mark E.J.Hanotte, Olivier H.Tapio, M.[Genome-wide analysis reveals the ancient and recent admixture history of East African Shorthorn Zebu from Western Kenya]Genome-wide analysis reveals the ancient and recent admixture history of East African Shorthorn Zebu from Western Kenya

In natural populations, individuals may be infected with multiple distinct pathogens at a time. These pathogens may act independently or interact with each other and the host through various mechanisms, with resultant varying outcomes on host health and survival. To study effects of pathogens and...


Thumbi, S.M.Bronsvoort, B.M. de C.Poole, Elizabeth J.Kiara, Henry K.Toye, Philip G.Mbole-Kariuki, Mary N.Conradie, I.Jennings, A.Handel, I.G.Coetzer, J.A.W.Steyl, J.C.A.Hanotte, Olivier H.Woolhouse, Mark E.J.[Parasite co-infections and their impact on survival of indigenous cattle]Parasite co-infections and their impact on survival of indigenous cattle

The presence of bluetongue virus (BTV) and Epizootic Haemorrhagic Disease virus (EHDV) in indigenous calves in western Kenya was investigated. Serum was analysed for BTV and EHDV antibodies. The population seroprevalences for BTV and EHDV for calves at 51 weeks of age were estimated to be 0.942 (...


Toye, Philip G.Batten, C.A.Kiara, Henry K.Henstock, M.R.Edwards, L.Thumbi, S.M.Poole, Elizabeth J.Handel, I.G.Bronsvoort, B.M. de C.Hanotte, Olivier H.Coetzer, J.A.W.Woolhouse, Mark E.J.Oura, C.A.L.[Bluetongue and epizootic haemorrhagic disease virus in local breeds of cattle in Kenya]Bluetongue and epizootic haemorrhagic disease virus in local breeds of cattle in Kenya

The passive transfer of antibodies from dams to offspring via colostrum is believed to play an important role in protecting neonatal mammals from infectious disease. The study presented here investigates the uptake of colostrum by 548 calves in western Kenya maintained under smallholder farming, ...


Toye, Philip G.Handel, I.Gray, J.Kiara, Henry K.Thumbi, S.M.Jennings, A.Wyk, I.C. vanNdila, M.Hanotte, Olivier H.Coetzer, K.Woolhouse, Mark E.J.Bronsvoort, B.M. de C.[Maternal antibody uptake, duration and influence on survival and growth rate in a cohort of indigenous calves in a smallholder farming system in western Kenya]Maternal antibody uptake, duration and influence on survival and growth rate in a cohort of indigenous calves in a smallholder farming system in western Kenya

This paper is the first attempt to accurately describe the hematological parameters for any African breed of cattle, by capturing the changes in these parameters over the first 12 months of an animal’s life using a population based sample of calves reared under field conditions and natural diseas...
