Figures
- FIG. 1.
PFGE of MRSA isolates recovered after identification of the LR-MRSA isolate (isolate CM-05; arrow). The isolate nomenclature is the same as that in Table 1. Additional isolates include isolate P, MRSA CHL93, representative of the Chilean clone; isolate S, MRSA HDE3, representative of the pediatric clone; and isolate T, S. aureus NCTC 8325, used as a control.
- FIG. 2.
Etest of LR-MRSA CM-05. The first halo of inhibition was evident at 24 h (interpreted as an MIC of 2 μg/ml; black arrow). After an additional 24 h of incubation, a second halo of growth was identified (MIC, 16 μg/ml; arrowhead).
