Infection of a total knee arthroplasty with Streptococcus bovis in a 76-year-old man that led to the diagnosis of a bowel carcinoma is reported. Investigation revealed a malignancy in the ascending colon with extension into the adrenal gland. S bovis in conjunction with colonic neoplasia has been reported in several orthopedic conditions: vertebral osteomyelitis, discitis, lateral neck abscess, and osteomyelitis of the ileum. The relationship of S bovis to endocarditis, meningitis, brain abscesses, and peritonitis has also been well described. However, S bovis is a rare pathogen infecting joint prostheses and should raise the possibility of a gastrointestinal lesion.
报道了一名76岁男性全膝关节置换术后感染牛链球菌，进而诊断出肠癌的病例。调查发现升结肠有恶性肿瘤并已蔓延至肾上腺。在几种骨科病症中都有牛链球菌与结肠肿瘤相关的报道：椎体骨髓炎、椎间盘炎、颈部外侧脓肿和回肠骨髓炎。牛链球菌与心内膜炎、脑膜炎、脑脓肿和腹膜炎之间的关系也有详细描述。然而，牛链球菌是一种罕见的感染关节假体的病原体，应提高存在胃肠道病变的可能性。
