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 paper describes the formulation of a transmission dynamic model for C. ruminantium in which the clinical manifestations of infection, namely heartwater disease and death, are the outcomes of interest and are Reported as functions of relative tick challenge. An outline of the model developed and the corresponding mathematical details are presented.
