Implication

Whole genome sequencing reveals compensatory mutations in multidrug resistant M. tuberculosis isolates, suggesting implications for treatment strategies.

Key Points

To analyze compensatory mutations in RNAP encoding genes of multidrug resistant M. tuberculosis in Uganda.
Studied 52 M. tuberculosis clinical isolates (20 drug-susceptible and 32 multidrug resistant)
Conducted whole genome sequencing and Sanger DNA sequencing
Identified mutations in rpoA, rpoB, rpoC genes
75% of multidrug resistant isolates had high-level rifampicin-resistance-conferring mutations in rpoB/RRDR
Identified putative compensatory mutations in rpoC, particularly Gly594Glu and Val483Ala
Non-synonymous mutations were prevalent in MDR-TB isolates
