Staphylococcus aureus and other Gram negative bacteria produce small colony variants (SCV) which usually emerge after exposure to antimicrobials. They cause repeated infections, treatment failures and often pass unnoticed during cultures due to unusual appearance and incomplete incubation. This infectious disease grand round highlights a similar clinical case with atypical history and appearance of a SCV of S. aureus and why prolonged incubation is necessary for aspirates from patients with recurrent infections like abscesses.

由金黄色葡萄球菌的小菌落变体引起的社区获得性感染。


金黄色葡萄球菌和其他革兰氏阴性细菌产生小的菌落变异体（SCV），通常在暴露于抗菌剂后出现。它们会引起反复感染，治疗失败，并且由于异常的外观和不完全的孵化而在培养过程中常常被忽视。这一传染病大事件突出了一个类似的临床案例，该案例具有非典型病史和金黄色葡萄球菌SCV的出现，以及为什么对于反复感染（如脓肿）患者的吸出液需要长时间孵育。
