Polymorphic, multicopy gene families are frequently located in subtelomeric regions of the genomes of parasitic protozoa. Theileria parva telomere-associated (TA) DNA from two chromosomes contained long open reading frames (ORFs) 54% identical at the N-termini whose ends were 2670 and 2680 bp fro...

Field and experimental bovine infection sera were used in immunoblots of sporozoite and schizont lysates of Theileria parva to identify candidate diagnostic antigens. Four parasite antigens of Mr 67,000 (p67), 85,000 (the polymorphic immunodominant molecule, PIM), 104,000 (p104), and 150,000 (p15...

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 polymorphic immunodominant molecule (PIM) of Theileria parva is expressed by the schizont and sporozoite stages of the parasite. We have recently cloned the cDNA encoding the PIM antigen from two stocks of the parasite: the cattle-derived T. parva (Muguga) stock and a buffalo-derived stock. T...

A stage-specific surface antigen of Theileria parva, p67, is the basis for the development of an anti-sporozoite vaccine for the control of East Coast fever (ECF) in cattle. By Pepscan analysis with a series of overlapping synthetic p67 peptides, the antigen was shown to contain five distinct lin...
