This paper studies East Coast fever (Theileria parva infection) risk in four district smallholder-farming areas of Kenya representing a range of epidemiological states of the disease. The areas include Kakamega, where indigenous cattle are intensively grazed with minimal tick control under modera...

Heartwater is a disease of high mortality in domestic ruminants (cattle, sheep and goats) in sub-Saharan Africa and in the Caribbean. An intracellular rickettsia, Cowdria ruminantium, is the cause of the disease and is transmitted by ticks of the genus Amblyomma. Losses due to heartwater are high...

Tick-borne diseases are considered a major constraint to dairy farming among the smallholder dairy farms in Kenya, which account for an estimated 75-90% of all milk produced in the country. The most important tick-borne disease in Kenya is East Coast fever (ECF) caused by Theileria parva and tran...
