p value** |
|---|---|---|---|---|
| Amikacin non-susceptibilitya | 17 (77.3%) | 4 (80%) | 1 (33.3%) | 0.313 |
| Gentamicin non-susceptibility | 22 (100%) | 3 (60%) | 2 (66.7%) | 0.013 |
| Ceftazidime non-susceptibility | 22 (100%) | 5 (100%) | 1 (33.3%) | 0.007 |
| MHT positive | 14 (63.6%) | 4 (80%) | 2 (66.7%) | 1.000 |
aNon-susceptible = intermediate sensitive + resistant
