Characterization of Pasteurella multocida isolated from rabbits in Canada
Summary
This study identified the main Pasteurella multocida serotypes in Canadian domestic rabbits. Serotype 12:A was most common in respiratory infections, while serotype 3:D was prevalent in acute pneumonia.
Area of Science:
- Veterinary Microbiology
- Rabbit Pathology
- Bacteriology
Background:
- Pasteurella multocida is a significant bacterial pathogen in domestic rabbits.
- Understanding the prevalent serotypes and their association with disease is crucial for effective disease management in rabbit populations.
Purpose of the Study:
- To determine the somatic and capsular serotypes of Pasteurella multocida in domestic rabbits in Canada.
- To investigate the association between specific Pasteurella multocida serotypes and different types of infections in rabbits.
Main Methods:
- Samples were collected from various sources including research facilities, commercial rabbitries, and abattoir/necropsy specimens.
- Isolates were obtained from upper respiratory tract infections, bronchopneumonia, pneumonia, abscesses, and otitis media.
- Somatic and capsular serotyping was performed on 59 Pasteurella multocida isolates.
Main Results:
- The most common serotypes identified were 12:A (47.0%), 3:D (30.5%), and 3:A (12.0%).
- Somatic group 3 was frequently isolated from acute pneumonic disease.
- Serogroup 12:A was predominantly found in upper respiratory tract infections and chronic bronchopneumonia.
Conclusions:
- Serotypes 12:A and 3:D are significant causes of respiratory disease in Canadian domestic rabbits.
- The findings highlight the importance of serotyping for targeted disease control strategies in rabbit farming.
- Most isolated Pasteurella multocida strains exhibited susceptibility to common antibiotics.
