Invasive Pasteurella multocida sinusitis in a renal transplant patient.

Pasteurella are commensal gram-negative bacteria isolated from the oral cavity of many domesticated animals. Most human infections occur post animal bite or scratch injury resulting in local cutaneous infection; however, case reports suggest that transmission may occur via animal secretions. Pasteurella species can be associated with serious systemic infections particularly in those with underlying disease and in the immunocompromised. We present a case of invasive Pasteurella multocida sinusitis in an immunocompromised renal transplant patient most likely acquired from a pet dog through direct mucosal inoculation via licking.
