FIG 2.

Mixed-strain colonization over follow-up in participants positive and negative for S. aureus at recruitment. (A) Number of recruitment-positives with single- or mixed-strain colonization over time. (B) Number of recruitment-negatives with single- or mixed-strain colonization over time. (C) Percentage of recruitment-positives with S. aureus isolated at each time point who had mixed-strain colonization with any unrelated strains versus all related strains over time. Lines at 3 and 5% are for reference. (D) Percentage of recruitment-negatives with S. aureus isolated at each time point who had mixed-strain colonization with any unrelated strains versus all related strains over time. Lines at 3 and 5% are for reference. Relatedness was predefined as a BURP distance of ≤6.
