---|---|---|---|
At enrollment, n = 600 | At 6-mo visit, n = 502 | At 12-mo visit, n = 426 | |
MRSA | 79‡ (13) | 66‡ (13) | 62‡ (15) |
MSSA | 180 (30) | 156 (31) | 118 (28) |
No S. aureus | 341 (57) | 280 (56) | 246 (58) |
*MRSA, methicillin-resistant S. aureus; MSSA, methicillin-susceptible S. aureus; PFGE, pulsed-field gel electrophoresis.
†Obtained from nares and groin swab specimens.
‡MRSA and MSSA co-colonization was detected in 11 participants at baseline, 10 participants at 6 mo, and 9 participants at 12 mo. For analysis these participants were classified as MRSA colonized. In addition, MRSA colonization with 2 distinct MRSA PFGE patterns was detected in 2 participants at baseline, 1 participant at 6 mo, and 2 participants at 12 mo.
