Bovine herpesvirus 4 (BoHV-4) has been isolated from cattle throughout the world. Interestingly, a survey of wild African buffaloes mainly from the Maasai Mara Game Reserve in Kenya revealed that 94% of the animals tested had anti-BoHV-4 antibodies [Rossiter, P.B., Gumm, I.D., Stagg, D.A., Conrad...
The parasite strain specificity of CTL responses to Theileria parva varies among cattle immunized with the same parasite stock. We have investigated the influence of class I MHC on the strain specificity of CTL responses to T. parva in 19 cattle of defined class I phenotype immunized with either ...
Theileria parva, a tick-borne api-complexan protozoan parasite, causes East Coast fever (ECF) in cattle. Control of the disease by improved vaccination is believed to provide a sustainable solution. Class I MHC-restricted CD8+ cytotoxic T lymphocytes (CTL) directed at schizontinfected cells const...
Contagious bovine pleuropneumonia (CBPP) is one of the most important transboundary animal diseases in Africa. In recent years, CBPP has been found in countries like Botswana from where it was previously eradicated (Amanfu et al., 1998). There is growing evidence to indicate that the incidence of...
This paper determines whether contact between parasite-specific CD4+ T cells and CD8+ T cells is an essential requirement for helper function, additional experiments were performed using two-chamber culture plates incorporating semi-porous membranes. TpM were co-cultured with naive or immune CD8 ...
Immunity to the bovine apicomplexan parasite Theileria parva is associated with MHC-I restricted CD8+ T cell responses directed against the intralymphocytic schizont stage of the parasite. A number of schizont-stage antigens that are targets of CD8+ T cell responses from immune animals have been ...
