Correlation between aac(6′)Ib-cr, aminoglycoside and fluoroquinolone resistance.
| Antibiotics | Number of Resistant Isolates | Number of aac(6′)Ib-cr Positive Isolates (%) * | Person Correlation (r2) | p Value |
|---|---|---|---|---|
| Streptomycin | 61 | 19 (31) | 0.135 | 0.193 |
| Tobramycin | 43 | 17 (39.5) | 0.301 | 0.003 ** |
| Gentamycin | 43 | 13 (30.2) | 0.044 | 0.670 |
| Amikacin | 36 | 17 (47.2) | 0.374 | <0.01 *** |
| Ofloxacin | 39 | 9 (23) | 0.018 | 0.866 |
| Norfloxacin | 42 | 14 (33.3) | 0.1450 | 0.162 |
| Ciprofloxacin | 37 | 12 (32.4) | 0.152 | 0.142 |
* percent correlated to no. of resistant isolates of each antibiotic. p values were calculated by Fisher’s exact test. ** p value is significant at 0.05 level (2-tailed), *** p value is significant at 0.01 level (2-tailed).
