Summary Information

Morphology, Staining and Metabolism information at genera level (Pasteurella)

(Classification of bacterial species is an evolving discipline. The information in Wildpro has been carefully referenced to the source material, as far as possible. Readers requiring further clarification should consult the source materials and more recent publications. Classification information in Wildpro will be altered when clear and scientifically endorsed new information regarding taxonomic divisions becomes available to us.

This section is currently predominantly used in Wildpro to link different data types and demonstrate inter-relationships. It does not contain detailed information on the bacteria itself.)

Common synonyms Pasteurella gallicida, Bacterium multocidum
Notes Pasteurella spp. are normally commensal / parasitic on the mucous membranes of the upper respiratory and digestive tracts of mammals (rarely man) and birds. (B74) (B47) Pasteurella multocida not usually carried by healthy birds and its presence is usually associated with acute / chronic disease. (B47)

Three subspecies P.m. multocida, P.M. septica, P.m. gallicida and various serotypes. are associated with this disease. Capsular antigens A,B,D,E,F and somatic antigens 1-16 recognized. Mainly capsular antigen type A in birds and mostly somatic type antigen 1 reported in waterfowl, but also types 3 and 4 in the Atlantic flyway and 3, 4 and 12 in eiders Somateria mollissima in Maine (J1.19.w8, J1.26.w3, B15).
