Pasteurellosis To Mannheimiosis: Taxanomic Changes

A Review on Pneumonic Pasteurellosis (respiratory Mannheimiosis) with Emphasis on Pathogenesis, Virulence Mechanisms and Predisposing Factors

Pneumonic pasteurellosis is one of the most economically important infectious diseases of ruminants with a wide prevalence throughout the continents. The disease is characterized by an acute febrile course with severe fibrinous or fibrinopurulent bronchopneumonia, fibrinous pleurisy and septicaemia. Infected animals may die within a few days of the onset of clinical signs, but those which survi...

Pasteurellosis of Fishes

Pasteurella haemolytica antigens associated with resistance to pneumonic pasteurellosis.

Antigens associated with whole Pasteurella haemolytica biotype A serotype 1, a capsular carbohydrate-protein extract of the organism, and P. haemolytica leukotoxin were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Antigens of the electrophoresed preparations were detected by Western blotting (immunoblotting) with sera from cattle which were either nonvaccinated or vac...

Clinicopathological Attributes of Swine Pasteurellosis

Swine pasteurellosis was observed in descript as well as non-descript pigs of Chhattisgarh, India. Affected animals exhibited pyrexia, dullness, staggering gait, anorexia, serous nasal discharge and dyspnoea. Case fatality rate was 95% in adult animals and 100% in piglets. Typical lesions of oedematous swellings noted in the pharyngeal region, these swellings spread to the ventral cervical regi...

Sialic Acid metabolism and systemic pasteurellosis.

Pasteurella multocida subsp. multocida is a commensal and opportunistic pathogen of food animals, wildlife, and pets and a zoonotic cause of human infection arising from contacts with these animals. Here, an investigation of multiple serotype A strains demonstrated the occurrence of membrane sialyltransferase. Although P. multocida lacks the genes for the two earliest steps in de novo sialic ac...
