There is growing evidence that immunity of cattle to Cowdria ruminantium infection is mediated by T lymphocytes. C. ruminantium antigens that stimulate these responses are therefore of considerable importance to the development of a sub-unit vaccine against the disease. We have examined T cell re...

Enhancement of the induction of cytotoxic T-cell responses by immunostimulatory CpG oligodeoxynucleotides has been described in humans and mouse models. The present study attempted to address whether CpG has a similar effect in cattle. Immunisation of cattle with a recombinant form of the polymor...

Immunostimulatory CpG oligodeoxynucleotides enhance the induction of bovine CD4+ cytotoxic T-lymphocyte responses against the polymorphic immunodominant molecule of the protozoan parasite Theileria parva
Theileria parva, a tick-transmitted protozoan parasite related to Plasmodium spp., causes the disease East Coast fever, an acute and usually fatal lymphoproliferative disorder of cattle in Africa. Previous studies using sera from cattle that have survived infection identified a polymorphic immuno...

Heartwater (cowdriosis) is an infectious disease of domestic ruminants in Africa and the Carribean and is caused by a tick-borne intracellular rickettsial agent, Cowdria ruminantium. There is growing evidence that immunity of cattle to the disease is medicated by T. lymphocytes. Antigens that sti...

Major antigenic proteins 1 and 2 of Cowdria ruminantium are targets for T-lymphocyte responses of immune cattle
Immunity against the bovine intracellular protozoan parasite Theileria parva has been shown to be mediated by CD8 T cells. Six antigens targeted by CD8 T cells from T. parva-immune cattle of different major histocompatibility complex (MHC) genotypes have been identified, raising the prospect of d...
