摘要

This study examined the conservation of expression of a 31-kDa iron-regulated protein by serotypes of Pasteurella haemolytica and Pasteurella trehalosi associated with pasteurellosis of cattle and sheep. A polyclonal antibody prepared against the purified 31-kDa periplasmic iron-regulated protein fromP. haemolytica serotype A1 showed that all P. haemolytica serotypes expressed similar 31-kDa proteins with identical N-terminal sequences, whereas P. trehalosiserotypes expressed immunologically different 29-kDa proteins with a different N-terminal sequence. Antibody to the 31-kDa iron-regulated protein was a useful tool to distinguish similarities and differences of the iron-regulated proteins of P. haemolytica andP. trehalosi.
