The paper reviews the infectivity, cross-immunization experiments, and cattle vaccination of Zimbabwean cattle-derived Theileria parva (Boleni) sporozoite stabilates produced at the Central Veterinary Laboratory (CVL) in Harare between 1980 and 2003. The Boleni stock was first isolated in July 1978 ...

Eight cattle immunized with cattle-derived Theileria parva Boleni stabilate together with six susceptible controls were released in Dombawera Game Park on the Highveld of Zimbabwe. This coincided with Rhipicephalus appendiculatus nymphal activity. The cattle grazed together with African buffaloes (...

510 cattle were immunized using T. parva (Boleni) stock (Bolvac-1) without concurrent chemotherapy with tetracycline on 2 farms in Zimbabwe, both of which had a history of theileriosis. The stabilate had been titrated in Friesian calves to determine a 50% protective dose (PD50) and 2 or 3 (PD50s)...

An immunization procedure against T. parva infection in Zimbabwe (January disease) was developed based on inoculation of cattle with live cryopreserved T. parva (Boleni) sporozoites without oxytetracycline. 8492 cattle were immunized by this method from 1994 to 1996. A seroconversion in excess of...

Over 500 cattle of all age groups on 2 farms in Zimbabwe were immunized against theileriosis using the "infection and treatment" method, and disease prevalence and productivity was assessed during a period of 18 months. The immunizing stock, Theileria parva (Boleni), was isolated in Zimbabwe. None...

T. p. bovis isolates were tested for their immunizing capacity under natural field challenge on Willsbridge Farm in the highveld of Zimbabwe. 15 susceptible Sussex yearlings (about 14 months old) were immunized with the Boleni stock and 15 with a mixture of 3 isolates from the farm, using...

Theileria stocks were isolated from cattle in the Harare area of Zimbabwe and established in lymphoid cell cultures and as cryopreserved sporozoite stabilates in the laboratory. 14 stocks in culture were characterized by testing them with monoclonal antibodies (MAb) raised against T. parva parva ...
