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...
Minisatellite tandem repeat elements are well known components of vertebrate genomes, but have not yet been extensively characterized in lower eukaryotes. We describe two unusual. AT-rich minisatellites of the protozoan parasite Theileria parva whose sequences are unrelated to the G/C-rich `chi m...
Two recombinant vaccines against Theileria parva, based on a near full-length version of the sporozoite surface antigen p67 (p67635), or an 80 amino acid C-terminal section (p67C), were evaluated by exposure of immunized cattle to natural tick challenge in two sites at the Kenya Coast and one i...
The relationship of strain specificity of class I major histocompatibility complex-restricted parasite-specific cytotoxic T lymphocytes (CTL) responses and cross-protection was investigated in an effort to verify the role of CTL in protection. The parasite strain specificity of the CTL responses ...
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 tick-borne api-complexan protozoan parasite, causes East Coast fever (ECF) in cattle. Control of the disease by improved vaccination is believed to provide a sustainable solution. Class I MHC-restricted CD8+ cytotoxic T lymphocytes (CTL) directed at schizontinfected cells const...
