A nasal carriage survey for methicillin-resistant Staphylococcus aureus (MRSA) in an intensive care unit detected four strains of MRSA with reduced susceptibility to vancomycin. The vanA gene was found in two of these vancomycin-intermediate Staphylococcus aureus (VISA) strains. The absence of selective vancomycin pressure might have resulted in reduced expression of the resistant gene.
在重症监护病房进行的耐甲氧西林金黄色葡萄球菌(MRSA)鼻腔携带调查中,发现了四株对万古霉素敏感性降低的 MRSA。其中两株万古霉素中介金黄色葡萄球菌(VISA)菌株中发现了 vanA 基因。缺乏选择性万古霉素压力可能导致耐药基因表达降低。
