Abstract

This study aims to investigate the genetic characteristics of Mycobacterium tuberculosis strains responsible for extensively drug-resistant tuberculosis (XDR-TB) and to propose optimized treatment algorithms. A total of 280 clinical isolates from XDR-TB patients across Uzbekistan were subjected to whole-genome sequencing (WGS). Mutations in key resistance-associated genes (katG, rpoB, gyrA, rrl, Rv0678) were identified. High-resolution genotyping revealed the predominance of the Beijing lineage. Correlation analysis between genotypic profiles and clinical response enabled the development of individualized treatment algorithms. The findings highlight the importance of integrating molecular diagnostics into national TB control strategies to improve treatment outcomes and limit the spread of XDR-TB.
