Spoligotyping, phenotypic and genotypic characterization of katG, rpoB gene of M. tuberculosis isolates from Sahariya tribe of Madhya Pradesh India.

Our findings have revealed that EAI3_IND strain is the predominant strain infecting Sahariya. The incidence of isoniazid-R M. tuberculosis strain infection is high, with an increased propensity to evolve into MDR-TB. Therefore, the TB centres should also consider isoniazid-R status of the isolates along with CBNAAT before deciding the drug regimen for the patients.
