A 76-year-old man with a history of osteoarthritis presents with right leg erythema and inability to weight-bear and pain in his right shoulder. Synovial fluid cell count of the knee and shoulder showed abundant neutrophils, and cultures of the knee showed growth of Pasteurella multocida. The patient owned four cats with which he had frequent contact, but history and physical examination elicited no evidence of scratches or bites. This case highlights the invasive potential of Pasteurella multocida in an immunocompetent individual and its capacity to cause septic arthritis in the setting of frequent animal contact.
一名患有骨关节炎的76岁男性，出现右腿红斑、无法负重以及右肩部疼痛。膝关节和肩关节的滑液细胞计数显示有大量中性粒细胞，膝关节培养物显示多杀巴斯德菌生长。该患者养了四只猫，他经常与它们接触，但病史和体格检查未发现抓伤或咬伤的迹象。这个病例突出了多杀巴斯德菌在免疫功能正常个体中的侵袭潜力，以及在频繁接触动物的情况下导致化脓性关节炎的能力。
