Binding of bovine transferrin by Pasteurella multocida serotype B:2,5, a strain which causes haemorrhagic septicaemia in buffalo and cattle.
Pasteurella multocida serotype B:2,5, which causes haemorrhagic septicaemia in buffalo and cattle, was examined for the presence of transferrin-binding proteins. An 82-kDa iron-regulated outer membrane protein was found which specifically binds bovine transferrin. In contrast, P. multocida serotype B:3,4, associated with haemorrhagic septicaemia in feral ruminants, did not express transferrin-binding proteins. These results might indicate a role for transferrin binding in the pathogenesis of haemorrhagic septicaemia in cattle and buffalo.
