Pasteurella multocida septicemia caused by close contact with a domestic cat: case report and literature review

We report here a case of Pasteurella multocida infection caused by cat exposure presenting with septic shock, sinusitis, and pneumonia. The patient was a febrile 20-year-old woman who had been experiencing disturbed consciousness progressively. She had close contact with a domestic cat and had received some scratches on both arms. A magnetic resonance imaging (MRI) scan of the head showed a high intensity in the paranasal cavity, and a computed tomographic (CT) scan of the chest showed bilateral lung consolidations. The pathogen was identified as P. multocida by the cultures from blood and nasal discharge. She was given intensive antibiotic therapy with ceftriaxone and piperacillin, continuous hemodiafiltration (CHDF) therapy, and anticoagulation therapy. Owing to these therapeutic regimens, the septic shock was successfully treated without complications. We also review the literature on P. multocida septicemia.
