Yersinia enterocolitica strains isolated from beavers (Castor fiber)
Abstract:
Pseudocloacal swabs and palatine tonsils from beavers have been examined for the Yersinia enterocolitica presence. Thirty-six samples from 24 beavers were collected and subjected to bacteriological examinations including sero- and biotypisation. Amplicons confirmed by PCR as Y. enterocolitica were sequenced. Positive samples originated from 4 out of the 24 beavers (16.7 %) and all the strains belonged to biotype 1A. The study suggested that Y. enterocolitica could be isolated from beavers, which may therefore be treated as a reservoir, a significant factor of water contamination and a vector of the Y. enterocolitica.
Insights
Yersinia enterocolitica was detected in 16.7% of beaver samples. Beavers may act as reservoirs and vectors for this bacterium, potentially contaminating water sources.
Area of Science:
- Veterinary Microbiology
- Zoonotic Disease Research
- Environmental Health
Background:
- Yersinia enterocolitica is a significant foodborne pathogen.
- Understanding reservoirs of Y. enterocolitica is crucial for public health.
- Beavers inhabit aquatic environments, increasing potential for pathogen transmission.
Purpose of the Study:
- To investigate the presence of Yersinia enterocolitica in beavers.
- To determine if beavers can serve as a reservoir for Y. enterocolitica.
- To assess the potential role of beavers in water contamination.
Main Methods:
- Bacteriological examination of pseudocloacal swabs and palatine tonsils from 24 beavers.
- Serotyping and biotyping of isolated strains.
- Polymerase Chain Reaction (PCR) and sequencing for confirmation.
Main Results:
- Yersinia enterocolitica was identified in 4 out of 24 beavers (16.7%).
- All confirmed Y. enterocolitica strains belonged to biotype 1A.
- Positive samples were obtained from both pseudocloacal swabs and palatine tonsils.
Conclusions:
- Beavers can harbor Yersinia enterocolitica.
- Beavers may act as a reservoir and vector for Y. enterocolitica transmission.
- Beaver populations could be a significant factor in water contamination with Y. enterocolitica.
