Disseminated Nocardia caviae infection with multiple positive blood cultures occurred in a bone marrow transplant recipient. Positive blood cultures are unusual in disseminated Nocardia infections and N caviea is an unusual species of Nocardia to cause infections in man, although its virulence in laboratory animals is similar to N asteroides. Multiple positive blood cultures in this case suggest a continuous or recurrent bacteremia rather than a transient bacteremia as previously has been thought to occur in disseminated Nocardia infections. The marked immunosuppressed state of the patient and an indwelling venous line could also have accounted for the recurrent bacteremia.
一名骨髓移植受者发生了播散性豚鼠诺卡菌感染，多次血培养呈阳性。在播散性诺卡菌感染中，血培养阳性并不常见，而且豚鼠诺卡菌是一种不常见的可引起人类感染的诺卡菌，尽管其在实验动物中的毒力与星形诺卡菌相似。该病例中多次血培养阳性提示为持续性或复发性菌血症，而非如既往认为的播散性诺卡菌感染中出现的短暂性菌血症。患者显著的免疫抑制状态和留置静脉导管也可能是复发性菌血症的原因。
