| Method | INH

|
Total (%) specimens | ||
|---|---|---|---|---|---|
| No. sensitive (%) | No. resistant (%) | No. sensitive (%) | No. resistant (%) | ||
| MODS | 65 (74) | 23 (26)a | 63 (72) | 25 (28)b | 88 (100) |
| MABA | 66 (75) | 22 (25) | 72 (82) | 16 (18) | 88 (100) |
a
Resistant at both low (0.1 μg/ml) and high (0.4 μg/ml) concentrations of INH.
b
Seven specimens were resistant at low (0.5 μg/ml) but susceptible at high (1.00 μg/ml) concentrations of RIF; two specimens were resistant at both low and high concentrations.
