Distribution of resistance phenotypes of MLSB based on the studied genes (mecA, ermA, ermC and msrA)
| Genes | Resistance phenotypes of isolates (%) | |||||
|---|---|---|---|---|---|---|
| R* (n=40) | HD (n=1) | D (n=11) | D+ (n=4) | N (n=1) | Total (n=57) | |
| Negative PCR (for all 4 genes) | 3 (7.5) | - | 5 (45.4) | - | - | 8 (14) |
| mecA | 5 (12.5) | - | 1 (9) | 1 (25) | 1 (100) | 8 (14) |
| mecA + ermA | - | - | 5 (45.4) | - | - | 5 (8.7) |
| mecA + ermC | - | - | - | 3 (75) | - | 3 (5.2) |
| mecA + ermA + ermC | 30 (75) | 1 (100) | - | - | - | 31 (54.3) |
| mecA + ermA + ermC + msrA | 2 (5) | - | - | - | - | 2 (3.5) |
R*: resistant phenotype; HD: hazy D zone phenotype; D: D phenotype; D+: D+ phenotype; N: negative phenotype.
