The main aim of this meeting was to review those developments in the fields of immunology and immunoparasitology that have relevance to the development of vaccination strategies for ECF and trypanosomiasis. Of relevance to the control of ECF were recent developments in the elucidation of events t...

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...

Invited review Novel vaccines against Theileria parva: prospects for sustainability
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...

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...

Peripheral blood mononuclear cells (PBMC) from immune cattle proliferate in the presence of autologous Cowdria ruminantium-infected endothelial cells and monocytes. Endothelial cells required treatment with T-cell growth factors to induce class II major histocompatibility complex expression prior...

Immunization of cattle by infection with Cowdria ruminantium elicits T lymphocytes that recognize autologous, infected endothelial cells and monocytes
Cattle were successfully immunized against heartwater with a lysate of Cowdria ruminantium formulated in Freund's adjuvant. Vaccinated animals proved fully resistant to virulent challenge 3 and 10 months after vaccination. For the first time a helper T lymphocyte response to Cowdria antigens was ...

A recombinant vaccine for Theileria parva
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...
