Summary
Five Erysipelothrix tonsillarum strains from dogs with endocarditis were identified as serovar 7. These canine isolates did not cause swine erysipelas, suggesting Erysipelothrix tonsillarum can be a pathogen in dogs.
Area of Science:
- Veterinary Microbiology
- Canine Pathology
- Bacterial Pathogenesis
Background:
- Erysipelothrix tonsillarum is a bacterium.
- Endocarditis is a serious heart infection.
Purpose of the Study:
- To identify and characterize Erysipelothrix tonsillarum strains isolated from dogs with endocarditis.
- To determine the pathogenic potential of these canine isolates.
Main Methods:
- Isolation of bacteria from canine endocarditis cases.
- Serotyping to determine serovar.
- Biochemical tests for metabolic activity.
- Pathogenicity tests in swine models.
Main Results:
- Five Erysipelothrix tonsillarum strains were isolated from dogs in Belgium.
- All isolates belonged to serovar 7.
- Isolates produced acid from saccharose.
- No clinical signs of erysipelas were observed in swine inoculated with these strains.
Conclusions:
- The isolated strains were confirmed as Erysipelothrix tonsillarum serovar 7.
- These findings suggest that certain strains of Erysipelothrix tonsillarum act as canine pathogens.
- The study highlights the role of E. tonsillarum in canine endocarditis.
