Staphylococcus aureus isolates from women with nasal, anal, or vaginal colonization were evaluated for population diversity by pulsed-field gel electrophoresis. Cluster analysis of restriction patterns revealed diversity indices of 0.89 and 0.99 for toxic shock syndrome toxin 1-positive and -negative isolates, respectively. Toxin-producing strains were isolated more frequently from the nares than from other sites.
通过脉冲场凝胶电泳对从鼻腔、肛门或阴道定植的女性中分离出的金黄色葡萄球菌进行群体多样性评估。对限制性酶切图谱的聚类分析显示,产毒性休克综合征毒素1的阳性和阴性分离株的多样性指数分别为0.89和0.99。产毒素菌株从鼻腔分离出的频率高于其他部位。
