*comprises all isolates resistant to the respective drugs (irrespective of other associated resistances).
**Isolates resistant to only INH (isoniazid), RIF (rifampicin), EMB (ethambutol), SM (streptomycin), or PZA (pyrazinamide), respectively.
***Strains resistant to 1, 2, 3, or 4 of the tested antibiotics (AB), no strain displayed resistance to all drugs.
