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
An observational longitudinal study was carried out on 92 randomly selected smallholder farms in two coastal lowland zones of Kwale District in Kenya between December 1997 and November 1999. The objective was to estimate the incidence of the main vector-transmitted diseases in pre-weaned calves. ...

The association between serum antibody titres to Theileria parva in calves and potential explanatory factors were examined in a longitudinal observational study that was conducted in 5 cohorts of female calves with a total of 225 calves on 188 smallholder dairy farms. The farms were distributed i...

Heartwater is a tick-borne disease of cattle, sheep and goats and some wild ruminants prevalent in much of Africa and the Caribbean. It is caused by the rickettsial organism Cowdria ruminantium and transmitted by ticks of the genus Amblyomma. The disease has traditionally been controlled by the u...
