| Phenotype | No. of isolates | No. (%) of strains with EPO phenotype |
|---|---|---|
| LvxS (adult, children) | 64 | 6 (9) |
| 42, 22 | 5 (12), 1 (5) | |
| LvxR | 79 | 48 (61) |
| LvxR-Only | 24 | 14 (58) |
| Lvx-BL | 10 | 10 (100) |
| Lvx-IPM | 34 | 19 (56) |
| Lvx-Other | 11 | 5 (45) |

The efflux pump-overexpressed (EPO) phenotype equals at least an eightfold decrease in FQ MIC in the presence of EPI; LVX was the FQ marker. P value < 0.0001 for LvxS versus LvxR overall, LvxR-Only, Lvx-BL, or Lvx-IPM subgroups; P value = 0.002 for LvxS versus Lvx-Other.
