Comparative study of genotypes of Mycobacterium tuberculosis from a Northern Indian setting with strains reported from other parts of India and neighboring countries

This study was carried out to characterize Mycobacterium tuberculosis population in Ghatampur, Kanpur, North India, by spoligotyping and Mycobacterial Interspersed Repetitive Units-Variable Number of Tandem Repeats (MIRU-VNTRs) typing. A total of 335 isolates were genotyped by spoligotyping and Central Asian (CAS) sub-lineage was the most prevalent, comprising 59.1% of all isolates. Other lineages were: East-African Indian (EAI) (19.10%), T (5.07%), Beijing (3.28%), Manu (2.98%), X (2.68%), S (0.89%), H3 (0.59%), Ural (0.59%), LAM 9 (0.29%) and unknown (5.37%).
