A 3-step procedure for cloning Theileria parva parasites was developed. The first step involved the in vitro infection of a fixed number of bovine lymphocytes with titrated sporozoites. The cell lines obtained from infections initiated using sporozoite/lymphocyte ratios below 1:100 were then sele...

Compulsory short-interval dipping of cattle for tick control has been enforced in Zimbabwe since the early part of this century. Intensive dipping was initially introduced as a measure to control East Coast fever (ECF), following its introduction from eastern Africa. Dipping was subsequently foun...

A large database on the transmission of a stabilate of the Theileria parva Muguga stock from one breed of cattle using two stocks of Rhipicephalus appendiculatus, Muguga and O1 Pejeta was developed and analysed. Factors associated with the ticks and cattle, and the infections developing in cattle...
