Rovis, L.Musoke, A.J.Moloo, S.K.[Immunization trials against trypanosomiasis using common antigens]Immunization trials against trypanosomiasis using common antigens

Theileria annulata and Theileria parva both poses a major surface antigen on the sporozoite stage of the life-cycle, called SPAG-1 and p67, respectively. In each case, these antigens are vaccine candidates and have been shown to induce a degree of homologous protection in earlier work. These anti...


Hall, R.Boulter, N.R.Brown, C.G.D.Wilkie, G.Kirvar, E.Nene, VishvanathMusoke, A.J.Glass, E.J.Morzaria, S.P.[Reciprocal cross-protection induced by sporozoite antigens SPAG-1 from Theileria annulata and p67 from Theileria parva]Reciprocal cross-protection induced by sporozoite antigens SPAG-1 from Theileria annulata and p67 from Theileria parva

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 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...

Nene, VishvanathIams, K.P.Gobright, E.I.Musoke, A.J.[Characterisation of the gene encoding a candidate vaccine antigen of Theileria parva sporozoites]Characterisation of the gene encoding a candidate vaccine antigen of Theileria parva sporozoites

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...


Nene, VishvanathInumaru, S.McKeever, Declan J.Morzaria, S.P.Shaw, M.Musoke, A.J.[Characterization of an insect cell-derived Theileria parva sporozoite vaccine antigen and immunogenicity in cattle]Characterization of an insect cell-derived Theileria parva sporozoite vaccine antigen and immunogenicity in cattle

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...

East Coast fever (ECF), caused by Theileria parva, is the most important tick-borne disease of cattle in much of eastern, central and southern Africa. In Kenya, immunization against ECF has been performed in many field trials using the infection and treatment method. The main targets for immuniza...

Heterologous priming-boosting vaccination regimens involving priming with plasmid DNA antigen constructs and inoculating (boosting) with the same recombinant antigen expressed in replication-attenuated poxviruses have recently been demonstrated to induce immunity, based on CD4(+)- and CD8(+)-T-c...

The major sporozoite surface antigen of Theileria annulata (SPAG-1) is a candidate for inclusion in a subunit vaccine. In this paper we summarize the results of 4 vaccination experiments using recombinant SPAG-1 expressed in different systems and presented in different adjuvants. The antigen has ...
