金黄色葡萄球菌(简称金葡前)是人类重要的致病菌,以往将其作为胞外致病菌。近年来发现该菌能够侵袭多种宿主细胞,并导致细胞死亡。但有关金葡菌侵袭和细胞毒性是否为临床分离株的共有特性及其对该菌致病性的作用尚不清楚。作者随机选择23个金葡菌临床分离株和参考菌株ATCC 29213作为研究对象,经随机扩增多态性 Staphylococcus aureus (referred to as pre-Portuguese) is an important human pathogenic bacteria, in the past as an extracellular pathogen. In recent years, it has been found that the bacterium can invade various host cells and cause cell death. However, it remains unclear whether the invasion and cytotoxicity of S. aureus are the common characteristics of clinical isolates and their effect on the pathogenicity of this bacterium. The authors randomly selected 23 Staphylococcus aureus clinical isolates and reference strains ATCC 29213 as a research object, the random amplified polymorphism
