Journal Article 2000

Autor: Gitau, G.K. McDermott, John J. Katende, J.M. Perry, Brian D.

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...

A postal questionnaire asking for data concerning heartwater deaths was sent to all large-scale commercial farmers in Zimbabwe's lowveld, where heartwater is endemic. One hundred and fifty returns (24 percent return rate) provided usable data, with 85 farms (57 percent of sample) reporting heartw...

As part of a series of studies associated with the development of improved vaccines for heartwater (a tick-borne disease of ruminant livestock caused by Cowdria ruminantium), field surveys were carried out to assess losses associated with the disease and the costs associated with controlling it i...

Autor: Gitau, G.K. Perry, Brian D. McDermott, John J.

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 longitudinal study was carried out in the coastal lowlands coconut¯cassava agro-ecological zone of Kaloleni Division, Coast Province, Kenya between June 1990 and December 1991 to estimate disease incidence and cause-specific case-fatality risk in an average of 120 cattle in 26 small-holder dai...

An alternative control option for heartwater (Cowdria ruminatium infection) is the establishment and maintenance of endemic stability which would lessen the existing dependence on acaricides. In an endemically stable state, animals become infected by vaccination or natural challenge at an early a...

Heartwater, caused by the rickettsial organism Cowdria ruminantium and transmitted by ticks of the genus Amblyomma, is considered to be the most important tick-borne disease of cattle in southern Africa, and is second only in importance to East Coast fever (theileriosis) in eastern Africa. This p...

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...
