Antibiotic susceptibility pattern of Staphylococcus aureus in prosthetic joint infection (PJI) and nasal commensal isolates.
| PJI (n = 100) | Nasal (n = 101) | |||
|---|---|---|---|---|
| Phenotype resistance *(%) | Genotype resistance (%) | Phenotype resistance (%) | Genotype resistance (%) | |
| Methicillin (mecA) | 1 (1.0) | 1(1.0) | 0 (0.0) | 0 (0.0) |
| Fusidic acid (fusB/C) | 1 (1.0) | 1 (1.0) | 1 (1.0) | 1 (1.0) |
| Erythromycin (ermA/B/C) | 1 (1.0) | 1 (1.0) | 1 (1.0) | 1 (1.0) |
| Clindamycin (ermA/B/C) | 2 (2.0) | 2 (2.0) | 1 (1.0) | 1 (1.0) |
| Gentamicin (aac-aphD) | 0 (0.0) | 0 (0.0) | 1 (1.0) | 1 (1.0) |
| Rifampin (rpoB) | 3 (3.0) | 1 (1.0) | 0 (0.0) | 0 (0.0) |
| Trimethoprim-Sulphamethoxazole (dfrA/dfrG) | 0 (0.0) | 0 (0.0) | 1 (1.0) | 0 (0.0) |
| Ciprofloxacin (gyrA/gyrB/parC/parE) | 6 (6.0) | 2 (2.0) | 0 (0.0) | 0 (0.0) |
*One PJI isolate was resistant to ciprofloxacin and rifampin, while the rest of the resistant isolates displayed resistance against one agent.
