Overlapping population structures of nasal isolates of Staphylococcus aureus from healthy dutch and American individuals

To understand Staphylococcus aureus nasal carriage and its relationship with subsequent disease, insight into the natural (nonclinical) bacterial population structure is essential. This study investigated whether the distributions of S. aureus genotypes that cause colonization differ by geographic locales. High-throughput amplified fragment length polymorphism (AFLP) analysis was performed on nasal isolates of S. aureus from healthy American (n=391) and Dutch (n=829) volunteers. In total, 164,970 binary outcomes, covering 135 different markers per isolate, were scored. Methicillin resistance w... Mehr ...
