title: The pneumococcal pilus predicts the absence of Staphylococcus aureus co-colonization in pneumococcal carriers.
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.
