Mycobacterium Interjectum isolated from an immunocompetent host with lung infection

Abstract

Improved molecular diagnostic techniques have resulted in increased reporting of nontuberculous mycobacterial infections. A 40-year-old male immunocompetent individual presented with cough and fever of 2-week duration. His chest X-ray showed cavities in the left upper zone and fibrosis in the right upper zone. His sputum was positive for AFB on Ziehl–Neelsen staining and showed slow-growing mycobacteria in mycobacteria growth indicator tube. The isolate was identified as Mycobacterium interjectum using GenoType® Mycobacterium CM assay (Hain Lifescience, GmBH, Nehren, Germany). At the end of a year's treatment, this first case from India has shown good progress.
