Prevalence of mutations in genes associated with isoniazid resistance in Mycobacterium tuberculosis isolates from re-treated smear-positive pulmonary tuberculosis patients: A meta-analysis

ConclusionINH resistance was spread widely and transmission of INH-resistant isolates, especially with katG315T mutation, was confirmed. Therefore, it is important to diagnose katG315T mutants among INH-resistant strains as it may be a risk factor for subsequent development of multidrug-resistant TB (MDR-TB). Prompt detection of patients with INH-resistant strains would expedite modification of treatment regimens, and appropriate infection control measures could be taken in time to diminish the risk of further development and transmission of MDR-TB.
