Abstract

The determinants of the negative association between Streptococcus pneumoniae and Stapylococcus aureus colonization are unknown. In this matched case-control study, the odds of co-colonization with S. aureus were significantly lower for individuals carrying a piliated versus a nonpiliated S. pneumoniae strain, suggesting the pilus may be a determinant of the negative association.

摘要

肺炎链球菌与金黄色葡萄球菌定植之间负相关的决定因素尚不清楚。在这项配对病例对照研究中,携带菌毛肺炎链球菌菌株的个体与金黄色葡萄球菌共同定植的几率显著低于携带非菌毛肺炎链球菌菌株的个体,这表明菌毛可能是这种负相关的一个决定因素。
