a
: 6 isolates (4 MSSA and 2 MRSA) inducible resistance to clindamycin.
b
: 7 isolates (1 MSSA and 6 MRSA) showing high-level mupirocin resistance.
c
: MIC range, 0.5∼2 μg/ml; 10 isolates (5 MSSA and 5 MRSA) MIC = 0.5 μg/ml; 89 isolates (38 MSSA and 51 MRSA) MIC = 1 μg/ml; 9 isolates (3 MSSA and 6 MRSA) MIC = 2 μg/ml.
P-value, two-sided P-value calculated by the chi-square or Fisher's exact test as appropriate.
