Rapid detection of multidrug-resistant mycobacterium tuberculosis using mycobacteria growth indicator tube [MGIT] system

ABSTRACT

Introduction: The emergence of drug-resistant tuberculosis has made the current epidemic worse. It can be prevented if patients with drug resistant tuberculosis are identified rapidly and treated with a combination of effective drugs. The method of proportion; the reference method advocated by the WHO, is known to provide reliable results in agreement with the outcome of patients but the required time is 6-8 weeks. MGIT is a new system of detection of mycobacterial growth based on an enriched 7H9 medium and a fluorescent indicator quenched in the presence of oxygen
