摘要

Acapsular hyaE deletion mutants of P. multocida can be administered to mammals, particularly ungulates, or birds to provide protective immunity against wild-type P. multocida, e.g., to prevent or reduce the severity of hemorrhagic septicemia or pneumonia in mammals, particularly livestock, ungulates, and companion animals, or fowl cholera in birds, particularly poultry.
