Pasteurellosis is an infection caused by inoculation usually through bites or scratches. Pasteurella multocida is involved in 50 to 60% of cases. Cats are the main vectors of the pathogen. Immunodepression increases the risk of systemic disease. We report a case of Pasteurella multocida pneumonia in an 81-year-old patient who had no cutaneous portal of entry. The patient had a past medical history of rectal neoplasia and prostate neoplasia treated with brachytherapy and hormonal therapy respectively. He had an environmental risk factor (the presence of a cat at home). The diagnosis was confirmed by repeated blood cultures. Antimicrobial therapy resulted in clinical, biological and radiological improvement. This case report raises the question of a possible pathogenesis different from the commonly described "inoculation".
巴氏杆菌病是一种通常通过咬伤或抓伤接种而引起的感染。多杀性巴氏杆菌参与了50%至60%的病例。猫是该病原体的主要传播媒介。免疫抑制会增加全身性疾病的风险。我们报告一例81岁无皮肤感染入口的多杀性巴氏杆菌肺炎患者。该患者既往分别有直肠肿瘤和前列腺肿瘤病史，曾接受近距离放射疗法和激素治疗。他存在环境危险因素（家中养猫）。通过反复血培养确诊。抗菌治疗使临床、生物学和影像学方面均得到改善。本病例报告提出了一种可能不同于通常所描述的“接种”发病机制的问题。
