Vancomycin-resistant Staphylococcus aureus (VRSA) and methicillin-resistant S aureus (MRSA) strains were examined in hospital effluents. Most S aureus strains are resistant to methicillin (MRSA), followed by tetracycline. Approximately 15% of MRSA strains are also resistant to vancomycin (VRSA). All VRSA strains developed a VanR/VanS-regulated 2-component system of VanA-type resistance in their genome. Results indicate that there is a possibility of developing resistance to aminoglycosides by VRSA strains in the near future.
对医院污水中的耐万古霉素金黄色葡萄球菌（VRSA）和耐甲氧西林金黄色葡萄球菌（MRSA）菌株进行了检测。大多数金黄色葡萄球菌菌株对甲氧西林耐药（MRSA），其次是对四环素耐药。约15%的MRSA菌株也对万古霉素耐药（VRSA）。所有VRSA菌株在其基因组中都形成了一种由VanR/VanS调控的VanA型耐药二元系统。结果表明，VRSA菌株在不久的将来有可能对氨基糖苷类药物产生耐药性。
