Cross-resistance profile of wild-type (WT) and paromomycin-resistant (PRr) L. donovani promastigotes
| Drug | Mean IC50 ± S.D. (µM) | |
|---|---|---|
| Wild-type | PRr | |
| Paromomycin | 50.0 ± 2.5 | 145 ± 3** |
| Pentamidine | 1.2 ± 0.3 | 1.8 ± 0.4* |
| Amphotericin B | 0.05 ± 0.01 | 0.07 ± 0.01* |
| Sb V | 35 ± 4.2 | 23 ± 1.4* |
| Miltefosine | 15.6 ± 0.25 | 10.4 ± 0.4* |
IC50s were determined in promastigotes of paromomycin-sensitive and Paromomycin-resistant strains after 72 h of drug addition. IC50 are given as means ± S.D. of at least two independent determinations with triplicates in each set.
Not significantly different from the corresponding wild-type values.
Statistically different at P<0.0001 when compared to the corresponding values obtained for wild type (WT).
