Mechanisms of Quinolone Resistance for Salmonella
| Serovar | Mechanism | MICcip (μg/mL) | No. of isolates | MLST | Country of origin |
|---|---|---|---|---|---|
| Salmonella Enteritidis | D87G gyrA | 0.25 | 1 | ST11 | Ghana |
| Salmonella Agama | D87G gyrA | 2 | 1 | ST28 | Ghana |
| Salmonella Poona | T57S parC**, qnrB2 | 0.5 | 3 | ST308 | Ghana |
| Salmonella Poona | T57S parC**, qnrB2 | 0.5 | 1 | Unknown | Unknown* |
| Salmonella Kentucky | D87Y + S83F gyrA; T57S, S80I parC | 16 | 3 | ST198 | Ghana |
| Salmonella Kentucky | T57S parC, qnrB19 | 0.5 | 1 | ST314 | Ghana |
*
Isolate imported: unknown country of origin.
**
T57S mutation in parC is not or doubtfully responsible for resistance phenotype (Wasyl et al. 2014).
CIP, ciprofloxacin; MLST, multilocus sequence typing; ST, sequence type.
