Rhodococcus equi, formerly known as Corynebacterium equi, was isolated repeatedly from the blood of two patients with the acquired immune deficiency syndrome (AIDS). Neither of the patients had pneumonia while they were bacteraemic, whereas pneumonia has been present in all previously reported cases of human infection with R equi. One of our patients had diarrhoea and the organism was isolated from a stool culture; the other patient had a large granulomatous soft tissue mass in his pelvis caused by R equi. Both isolates were resistant to penicillin and one produced a beta-lactamase. Both patients were treated with vancomycin but only one recovered.
马红球菌，以前称为马棒状杆菌，曾从两名获得性免疫缺陷综合征（艾滋病）患者的血液中反复分离出来。这两名患者在菌血症期间均无肺炎，而在先前报道的所有人类感染马红球菌的病例中均存在肺炎。我们的一名患者有腹泻，该菌从粪便培养物中分离出来；另一名患者盆腔有一个由马红球菌引起的巨大肉芽肿性软组织肿块。两种分离株均对青霉素耐药，其中一株产生β-内酰胺酶。两名患者均接受了万古霉素治疗，但只有一名康复。
