We analyzed the emergence of daptomycin nonsusceptibility in a patient with persistent vancomycin-intermediate Staphylococcus aureus (VISA) bacteremia. The daptomycin-nonsusceptible VISA's cell wall demonstrated a reduction in muramic acid O-acetylation, a phenotypic parameter not previously reported for VISA; some isolates also contained a single point mutation in the mprF gene.
我们分析了一名患有持续性万古霉素中介金黄色葡萄球菌(VISA)菌血症患者中达托霉素不敏感情况的出现。达托霉素不敏感的VISA的细胞壁显示出胞壁酸O-乙酰化减少,这是一个此前未在VISA中报道过的表型参数;一些分离株在mprF基因中还存在单点突变。
