Full-length recombinant versions of p67, the 709 amino acid major surface protein of Theileria parva sporozoites, induce immunity to East Coast fever (ECF) in cattle. We show that a soluble Escherichia coli recombinant version of p67 (p67635), in which a prokaryotic signal peptide replaces the e...

Two novel baculovirus-derived recombinant Theileria parva p67 constructs were tested for their vaccine potential against East Coast fever. Boran calves were immunized with a his-GFP-p67 fusion protein (GFP:p67DeltaSS) or with GP64:p67C, a protein fusion between a C-terminal domain of p67 and th...
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...

Subunit vaccine based on the p67 major surface protein of Theileria parva sporozoites reduces severity of infection derived from field tick challenge
Initial laboratory trials of an experimental subunit vaccine against Theileria parva based on the 67-kDa major sporozoite surface antigen revealed a range of responses to challenge. We have analyzed convergence in seven sets of monozygotic twins which suggests that genetic factors may have an i...

Two experiments were carried out to identify the target population of cattle for immunisation against East Coast fever (ECF) using the infection-and-treatment method. Firstly, a sentinel-calf study was used to determine the age window for ECF immunisation by determining ages at clinical detection...
