Mannheimia

Mannheimia

a genus of gram negative, facultatively anaerobic, rod-shaped bacteria in the family Pasteurellaceae. Formerly members of the genus Pasteurella. Contains the species M. haemolytica, M. glucosida, M. granulomatis, M. ruminalis and M. varigena. M. glucosida was serotype 11 of P. haemolytica biotype A; has low virulence and is largely an opportunistic pathogen of sheep. M. granulomatis associated with lechiguana, a focal proliferative fibrogranulomatous panniculitis in cattle. M. haemolytica (P. haemolytica biotype A) causes bovine pneumonic pasteurellosis and pneumonic and septicemic pasteurellosis in sheep, as well as pneumonia in wild bighorn sheep. A cause of septicemic pasteurellosis in sucking lambs. Viral infection, especially by parainfluenza virus 3, commonly predisposes animals to disease. A common cause of mastitis in sheep and occasional cause of acute mastitis in cattle.
