Pasteurella multocida in an infected tiger bite
Abstract:
We report an unusual case of Pasteurella multocida wound infection caused by a tiger bite. We investigated the normal fang flora of large zoo cats and found P multocida in cultures from seven tigers, three of four leopards, and one lynx. Sucrose fermentation was found to be highly media dependent and unpredictable. The literature relative to P multocida in bite-wound infections is reviewed with special reference to bites by animals other than cats and dogs. With the addition of the present case, the animals involved have been two rats, two opossums, two lions, one horse, one rabbit, one boar, one panther, and one tiger.
Insights
Pasteurella multocida is a common bacteria in large cats, posing a risk for wound infections from bites. This study found P. multocida in tigers, leopards, and lynx, highlighting potential zoonotic transmission risks.
Area of Science:
- Veterinary Microbiology
- Infectious Diseases
- Zoonotic Infections
Background:
- Pasteurella multocida (P. multocida) is a significant bacterial pathogen.
- Bite-wound infections are a common concern in both human and veterinary medicine.
- Large felids, such as tigers, can harbor P. multocida in their oral flora.
Observation:
- A case of P. multocida wound infection following a tiger bite is presented.
- Oral flora cultures from zoo-housed large cats revealed P. multocida in tigers, leopards, and lynx.
- Sucrose fermentation by P. multocida demonstrated significant media-dependent variability.
Findings:
- P. multocida is frequently present in the oral flora of large felids, including tigers.
- Tiger bites represent a potential vector for P. multocida transmission to humans.
- The study reviewed P. multocida in bite-wound infections from various animal species.
Implications:
- This research underscores the importance of considering P. multocida in wound infections resulting from exotic animal bites.
- Understanding the prevalence of P. multocida in large cats can inform preventative measures and treatment protocols.
- Further investigation into the pathogenicity and transmission dynamics of P. multocida from felids is warranted.
