金黄色葡萄球菌是临床上常见的致病性较强的细菌,是引起医院感染和社区获得性感染常见的致病菌之一。随着广谱抗生素的广泛使用,耐甲氧西林金黄色葡萄球菌(MRSA)的检出率越来越高。由于该菌对环境有较强的适应力,容易在医院内传播流行,已成为医院常见的革兰阳性菌之一,甚至在一些医院引起了暴发流行[1],这种来源于医院内的耐甲氧西林金黄色葡萄球菌被称为医院获得性MRSA(HA-MRSA)。另外,近年来在无医院或医疗机构接触史的
Staphylococcus aureus is a common pathogenic bacteria in clinical practice. It is one of the common pathogens causing nosocomial infections and community-acquired infections. With the widespread use of broad-spectrum antibiotics, the detection rate of methicillin-resistant Staphylococcus aureus (MRSA) is getting higher and higher. Because of its strong adaptability to the environment and its easy spread in hospitals, it has become one of the common Gram-positive bacteria in hospitals and even caused outbreaks in some hospitals [1] Methicillin-resistant Staphylococcus aureus is called hospital-acquired MRSA (HA-MRSA). In addition, there is no history of contact with hospitals or medical institutions in recent years
