Abstract:
Mannheimia granulomatis was first isolated from pneumonic European hares in the 1980s and has since been reported sporadically in pneumonic Swedish roe deer and Australian cattle. Although the pneumonic lesions caused by M. haemolytica in livestock have been extensively studied and reported, little is published with regard to the pneumonic lesions associated with M. granulomatis infection in any species. We describe the histopathology of purulent bronchopneumonia associated with M. granulomatis in a Belgian hare ( Lepus europaeus) resident in British Columbia, Canada, and compare the lesions with those caused by M. haemolytica in livestock.
Insights
Mannheimia granulomatis causes purulent bronchopneumonia in hares. This study details the histopathology of this condition, comparing it to Mannheimia haemolytica in livestock.
Area of Science:
- Veterinary Pathology
- Microbiology
- Comparative Pathology
Background:
- Mannheimia granulomatis is an infrequently reported bacterial pathogen.
- Pneumonic lesions caused by Mannheimia haemolytica in livestock are well-documented.
- Limited information exists on M. granulomatis-associated pneumonia across species.
