[Arthritis due to Listeria monocytogenes].

A 69-year-old man with liver cirrhosis presented to a surgeon, complaining of pain and swelling involving the right knee joint. A cloudy yellow synovial fluid was aspirated. The examination revealed polymorphonuclear leukocytes and Listeria monocytogenes was grown in the culture. The patient was treated with oral cotrimoxazole. Further follow-up was uneventful. The literature on listerial joint infections is briefly reviewed.
