A live, attenuated vaccine is currently the only viable option to control of CBPP in Africa. It has been suggested that simple modifications to current vaccines and protocols might improve efficacy in the field. In this report we compared the current vaccine formulation with a buffered preparatio...

Theileria parva is an intracellular sporozoan parasite that infects and transforms bovine lymphocytes, causing a severe lymphoproliferative disease known as East Coast fever in eastern, central and southern Africa. In this article, Declan McKeever and colleagues summarize the current understandin...

A first-gneration subunit vaccine for East Coast fever based on the Theileria parva p67 sporozoite surface antigen is entering preliminary field trials. Intensive efforts are also focused on the identification of a schizont-specific omponen for incorporation in a second-generation multi-component...

Previous data showed that six out of a group of nine cattle inoculated with NS1-p67, a recombinant form of a 67-KDa Theileria parva sporozoite surface protein, were immune to East Coast fever. This bacterialy expressed antigen encoded all 709 amino acid residues of p67 fused to the C-terminal end...

Development of improved vaccine and diagnostic-based disease control strategies has benefited considerably from advances in biotechnology, particularly those relating to recombinant DNA technology. Efficiency of the vaccine development process has been increased at all levels, from the analysis o...

Studies of the immune responses of cattle to Theileria parva have provided evidence that immunity to the parasite can operate at two levels, namely the sporozoite and the schizont-infected lymphoblast. Antibodies that neutralize the infectivity of sporozoites have been detected in the serum of hy...

The Development of a recombinant Theileria parva vaccine is discussed under the following headings: mechanisms of protection against ECF [East Coast fever]; cloning and expression of p67; immunization and challenge of cattle; interpretation of immunization and challenge data.

Theileria parva, a protozoan parasite of cattle, causes a disease called East Coast fever. The disease is of economic importance because it causes high morbidity and mortality and limits the development of the cattle industry. This paper highlights the experiences with immunization against Theile...
