Recombinant bovine IFN gamma is a potent inhibitor of Cowdria ruminantium growth in vitro irrespective of the rickettsial stock, or the origin of the endothelial cells. These results suggest an important role for IFN gamma in protective immune responses against C. ruminantium infections. Here we ...

Recombinant bovine interferon gamma inhibits the growth of Cowdria ruminantium but fails to induce major histocompatibility complex class II following infection of endothelial cells
Understanding the basis of protective immunity to Cowdria ruminantium will facilitate the development of an effective subunit vaccine against heartwater in ruminants and contribute to a better definition of protective immune mechanisms to obligate intracellular pathogens in general. Until recentl...

Immune responses to Cowdria ruminantium infections
We describe a highly sensitive, non-radioactive assay for T cell activation, based on the rapid induction of class II MHC expression by constitutively negative bovine endothelial cells, when cultured in the presence of supernatants derived from activated bovine T cells. We demonstrate the effecti...
