Pasteurella multocida capsule: composition, function and genetics.

Author information

Department of Microbiology, Monash University, Vic. 3168, Clayton, Australia.


Pasteurella multocida is an important animal pathogen and many strains express a polysaccharide capsule. The antigenicity of the capsule can be used to identify five serogroups A, B, D, E and F. Disease predilection is generally related to serogroup, with haemorrhagic septicaemia strains belonging to serogroups B or E and fowl cholera strains to serogroup A. The importance of the capsule in virulence has been implicated in a number of studies but these studies have been hampered by a lack of isogenic strains and an understanding of capsule biosynthesis at the molecular level. Recently, the nucleotide sequences and genetic organisation of the capsule biosynthetic loci have been determined for strains of P. multocida serogroups A and B.
