International Journal of Mycobacteriology, a publication of Asian African Society of Mycobacteriology, is a peer-reviewed online journal with Quarterly print on demand compilation of issues published. The journal’s full text is available online at http://www.ijmyco.org. The journal allows free access (Open Access) to its contents and permits authors to self-archive final accepted version of the articles on any OAI-compliant institutional / subject-based repository.The Mycobacteria Growth Indicator Tube (BBL MGIT 960) is a Middlebrooks 7H9 broth-based culture method, with an oxygen-sensitive fluorescent sensor to indicate microbial growth. The principal advantages of the MGIT system over the BACTEC 460 system include no need for needle inoculation, and therefore better biosafety, and reduced opportunity for cross-contamination of cultures, no radioisotopes, and the option for manual culture examination using an ultraviolet light, rather than with a special (expensive) instrument. Its limitations include higher (non-mycobacterial) contamination rates than solid culture methods and reduced performance when blood is present in the specimen
