Session one of this report highlights ILRAD's research programs and the modelling needs of ILRAD and FAO. Session two deals with vector and helminth population dynamics with particular reference to ticks, tsetse and helminth. Parasite transmission and host parasite interaction are discussed in se...

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...

Heartwater, an infectious disease of ruminants caused by the rickettsia Cowdria ruminantium (transmitted by ixodid ticks of the genus Amblyomma and vertically), severely constrains livestock production throughout sub-Saharan Africa. Its epidemiology varies from epidemics with high mortality (on i...
