<p>A vaccine against infections caused by Pasteurella haemolytica comprises at least one capsular associated antigen obtained from Pasteurella haemolytica. The vaccine generally contains capsular associated antigens obtained from more than one serotype of Pasteurella haemolytica, the serotype chosen depending on the species of animal for which the vaccine is intended and the geographical location of the animals. The vaccine may also comprise other microbial or viral antigens, the choice of other antigen(s) again being dependent on the intended use of the vaccine. The invention also provides an antiserum against a capsuler associated antigen of Pasteurella haemolytica, which antiserum may be used for passive immunization against Pasteurella haemolytica infections.</p> |
