We report recurrent bacteremia due to mixed infection with two clonally derived isolates of Staphylococcus aureus in a patient with Sezary syndrome. The two isolates, one gentamicin resistant and methicillin susceptible and the other gentamicin susceptible and methicillin resistant, developed by the deletion of the mecA, ant(4')Ia, and aacA-aphD genes from a common gentamicin-resistant and methicillin-susceptible ancestor.
我们报告了1例蕈样肉芽肿综合征患者因两种克隆衍生的金黄色葡萄球菌分离株混合感染导致复发性菌血症。这两种分离株,一种对庆大霉素耐药但对甲氧西林敏感,另一种对庆大霉素敏感但对甲氧西林耐药,它们是由一个共同的对庆大霉素耐药且对甲氧西林敏感的祖先菌株通过缺失mecA、ant(4')Ia和aacA-aphD基因而产生的。
