Invasive Pasteurella multocida sinusitis in a renal transplant patient

Area of Science:

• Microbiology
• Infectious Diseases
• Immunocompromised Hosts

Background:

• Pasteurella are gram-negative bacteria commonly found in domestic animals' oral cavities.
• Human infections typically result from animal bites or scratches, causing localized skin infections.
• Systemic Pasteurella infections are a risk for immunocompromised individuals and those with underlying health conditions.

Observation:

• A case of invasive Pasteurella multocida sinusitis is presented.
• The patient was an immunocompromised individual who had undergone a renal transplant.
• The infection was likely acquired from a pet dog through direct mucosal contact (licking).

Findings:

• This case demonstrates a rare transmission route of Pasteurella multocida via direct mucosal inoculation from a pet.
• Invasive sinusitis developed in an immunocompromised patient, emphasizing the potential for severe outcomes.
• The findings suggest that close contact with pets, including licking, can pose an infection risk.

Implications:

• Healthcare providers should consider non-bite transmission routes for Pasteurella infections in immunocompromised patients.
• Pet owners who are immunocompromised should be aware of potential infection risks from animal secretions.
• Further research is needed to understand the full spectrum of Pasteurella transmission and associated risks in vulnerable populations.
