The purpose of the study was to characterize the differences in epidemiology (risks of infection. morbidity. mortality) and potential control of East Coast fever (ECF) between the selected strata. Evidence of Theileria parva infection was assessed by increased antibody levels as measured in an in...

The epidemiology of Theileria parva infections on smallholder dairy farms in Kenya
The Murang'a District is situated in central Kenya and is a highland area with a high potential for dairy production. This study was carried out to evaluate the performance of smallholder dairy farms by analysing available data and by simulation modelling. Eighteen case farms were selected non-ra...

Since 1989, a step-wise series of farming systems surveys and epidemiological studies have been carried out in coastal Kenya to identify and resolve major disease constraints affecting smallholder dairy production. This paper describes the sequential studies and reports on the significance of, an...

A prospective observational study was conducted among smallholder dairy farmers in Murang'a District, Kenya, to estimate the incidence of Theileria parva infections, as well as calf morbidity and mortality caused by the infection. The study was conducted between March 1995 and August 1996, in fiv...

A cross-sectional study was carried out from July to September 1989 in Kaloleni Division, Coast Province, Kenya to estimate the prevalence of vector-transmitted diseases in small-holder dairy cattle and to identify the risk factors associated with different management systems. One hundred and thi...

The most important tick-borne disease of cattle in eastern, central and southern Africa is East Coast fever (ECF) caused by Theileria parva and transmitted by the tick Rhipicephalus appendiculatus. Other less-important tick-borne diseases in cattle are benign theileriosis caused by Theileria muta...
