Advances in the Control of Theileriosis. Proceedings of an International Conference held at the International Laboratory for Research on Animal Diseases in Nairobi, 9-13th February, 1981, 1981, pp 83-85
Abstract

Parasite stocks used in immunization programmes against East Coast fever in cattle in Kenya are discussed, with reference to treatment strategies and cattle reactions. Concerns were expressed that immunized cattle might show a reduction in productivity, Theileria parva from cattle would not protect ...

Abstract

Immunization strategies against East Coast fever in cattle in the Kilifi District, Kenya, are presented. The study area, a survey of ticks (including Rhipicephalus appendiculatus and Amblyomma spp.) and Theileria parasites, isolation of Theileria stocks, characterization of T. parva isolates, field ...

Abstract

This paper summarizes the results of a study conducted in Kenya in 1988 on the best method for assessing the cost to a government of producing and delivering the infection-and- treatment vaccine against East Coast fever in cattle in the field. The costs of developing and delivering the vaccine were ...

Abstract

2 stocks of T. parva were chosen from several isolates obtained from the Coastal Province of Kenya, and were used to inoculate cattle via the chemoprophylaxis technique. In a field trial at Mtwapa, 8 Jersey calves < one year of age were immunized against T. parva (Kilifi) and T. parva (Marikebuni) and exposed to unlimited tick challenge...

Abstract

Nymphs of Hyalomma impeltatum and H. dromedarii, fed as larvae on an infected calf, transmitted fatal T. annulata infection to 2 susceptible calves. Since immature stages of H. impeltatum feed on rodents, hares and birds, this tick is unlikely to transmit T. annulata to cattle in the Sudan. H....

Abstract

Two sets of oligonucleotide primers, one derived from a repetitive sequence and the other from the gene encoding of 67 000 MW sporozoite antigen of T. parva, were used to amplify parasite DNA from the blood of T. parva-infected carrier cattle using the polymerase chain reaction (PCR). PCR...

Abstract

T. parva parva Marikebuni stock, previously shown to give good protection to immunized cattle in Kilifi District, Coast Province of Kenya, was chosen for large scale immunization in the district. A large sporozoite stabilate was prepared and evaluated for efficacy and safety in the 'infection and...
