Novel and rare species of nontuberculous mycobacteria by Hsp-65 gene sequencing.

Background: Nontuberculosis mycobacterium (NTM) is the emerging group of organisms being recognized as etiological agents for diverse clinical conditions such as lymphadenitis, cutaneous, and pulmonary or disseminated lesions. Diverse background patients can acquire these infections such as immunocompetent, immunocompromised patients, or postoperative settings. Rapid addition of newer strains to this group necessitates heightened suspicion in the clinical settings.
