Three cases of Pasteurella multocida skin infection from pet cats

Area of Science:

• Veterinary Dermatology
• Infectious Diseases
• Zoonotic Infections

Background:

• Pasteurella multocida is a common bacterium found in the oral and nasal cavities of domestic animals, particularly cats.
• Skin infections caused by P. multocida can occur following animal bites or scratches.
• While P. multocida infections are well-documented globally, their occurrence in Japan's dermatological context is less frequently reported.

Observation:

• This report details three distinct cases of Pasteurella multocida skin infections originating from pet cats.
• Clinical presentation in these cases included the acute onset of significant erythema (redness), localized pain, and swelling at the site of infection.
• The patients presented with symptoms indicative of a bacterial skin infection following contact with their pet cats.

Findings:

• Microbiological analysis confirmed Pasteurella multocida as the causative agent in all three cases.
• The infections exhibited a rapid progression, highlighting the potential virulence of P. multocida in skin wound settings.
• The clinical and microbiological findings align with known characteristics of P. multocida wound infections.

Implications:

• This case series underscores the importance of recognizing P. multocida as a potential pathogen in skin infections transmitted from pet cats.
• Dermatologists in Japan should be aware of the clinical signs and diagnostic approaches for P. multocida infections.
• Prompt diagnosis and appropriate antibiotic treatment are crucial for managing these zoonotic skin infections effectively.
