Young, A.S.Ochanda, H.Perry, Brian D.Morzaria, S.P.Dolan, T.T.Medley, G.F.Gettinby, G.[The biology of the transmission dynamics of Theileria parva]The biology of the transmission dynamics of Theileria parva

Heartwater, caused by the rickettsial organism Cowdria ruminantium, is a serious constraint to livestock development in much of sub-Saharan Africa. Traditionally, the disease has been controlled by the use of chemical acaricides to control the vector tick. The University of Florida/USAID-supporte...

Heartwater is a severe tick-borne, non-contagious disease of ruminant livestock caused by the rickettsia Cowdria ruminantium, which is endemic in much of sub-Saharan Africa and in the Caribbean. Transmission occurs via ticks of the Amblyomma genus, primarily A. variegatum and A. hebraeum. Intense...

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...
