Abstract

Pasteurella haemolytica is a cattle pathogen of significant economic impact. An effective vaccine against bovine pneumonic pasteurellosis is therefore of high importance. Apart from economic concerns, pasteurellosis caused by P. haemolytica is a serious disease leading to death in cattle if it remains untreated. In this study P. haemolytica-ghosts are presented as a promising vaccine candidate in cattle. To obtain sufficient vaccination material a fermentation protocol for P. haemolytica-ghost production was established. With the obtained experimental P. haemolytica-ghost vaccine, cattle immunization studies were performed based on a Pasteurella cattle challenge model developed specifically for vaccine validation. It was shown that protective immunization of cattle against homologous challenge was induced by adjuvanted P. haemolytica-ghosts. The level of protection was similar to a commercially available vaccine.
