Table 4 showed Pre-XDR TB detected among the age groups as follows: 15–24 years (3%), 25–34 years (6%), 35–44 years (8%), 45–54 years (1%) and ≥55 (3%). The frequency of mutation for rpoβ was WT 8, MUT2B (4), MUT 2B(4), WT 7 (5), WT 7, MUT3(4), WT 8, MUT3 (20), WT8 (7), WT 3, WT4 (5), MUT 2B, MUT3 (4), WT (4). inhA was WT (10), Kat G was WT (12) and WT MUT 1(15). Frequency of mutation for second line anti TB drugs were WT1, WT2 (9) and WT1 (4) for rrs; WT 1, WT2 (2), WT1 (1) for eis; WT 1, WT2, WT3 (3), WT3 (2) for gyrA (Table 5). Here, WT1 is linked to tuberculosis.
