Abstract INTRODUCTION: Cat bite infections usually involve a mix of anaerobic and aerobic bacteria including species of Pasteurella, Streptococcus, Staphylococcus, Bacteroides, and Fusobacterium. We report a case of Pasteurella multocida infection from cat bites leading to endocarditis and subsequent aortic valve replacement. PRESENTATION OF CASE: A 70-year-old male was admitted because of fever, tachycardia, and malaise. He had a history of alcohol abuse and was living alone with a cat in a rural area. A sepsis of unknown origin was suspected, and intravenous treatment with gentamicin and cefotaxime was initiated. Blood cultures yielded Pasteurella multocida, and the patient history revealed repeated cat bites. After four days, the patient was discharged with oral penicillin V treatment. Two weeks later, the patient returned with fever and a new systolic murmur. An aortic valve endocarditis was diagnosed, and it became clear that the patient had not completed the prescribed penicillin V treatment. The patient underwent a biological aortic valve replacement with debridement of an annular abscess, and the postoperative course was uneventful. DISCUSSION: Endocarditis due to Pasteurella is extremely rare, and there are only a few reports in the literature. Predisposing factors in the present case were alcohol abuse and reduced compliance to treatment. CONCLUSION: Cat bites are often deep, and in rare circumstances can lead to life-threatening endocarditis. Proper surgical revision, antibiotic treatment, and patient compliance are necessary components in patient care to avoid this complication. Copyright © 2016 The Author(s). Published by Elsevier Ltd..
