Drug Susceptibility Testing for M. tuberculosis Complex 1. Essentials for the Mycobacteriology Laboratory: Promoting Quality Practices 1.1 Drug Susceptibility Testing for M. tuberculosis Complex

Performance of the microscopic observation drug susceptibility assay in drug susceptibility testing for Mycobacterium tuberculosis.

The drug susceptibility testing performance of a broth-based method with microscopic reading of bacillary growth, the microscopic observation drug susceptibility (MODS) assay, was compared to that of the reference 7H10 agar method of proportion by using 53 isolates of Mycobacterium tuberculosis from persons at risk for multidrug-resistant TB. For isoniazid (0.1 micro g/ml) and rifampin (2.0 mic...

Nonweekend schedule for BACTEC drug susceptibility testing of Mycobacterium tuberculosis.

Determination of the drug susceptibility of Mycobacterium tuberculosis by conventional methods using an agar-based medium may take 3 weeks or more to complete. On the other hand, results on positive cultures are generally available in 4 to 7 days with the radiometric (BACTEC, Johnston Laboratories, Towson, Md.) procedure. One disadvantage to the latter is the requirement to determine the quanti...

Nitrate reductase assay for drug susceptibility testing of Mycobacterium tuberculosis.

In their recent article, Kristian Ängeby et al. (4) reported a novel test for drug susceptibility testing of Mycobacterium tuberculosis. However, it should be clarified that this method was previously published in 1989 (3) by Emil Kalfin, (National Institute for Lung Diseases, Sofia, Bulgaria) and Andreas Engibarov (National Center of Infectious and Parasitic Diseases, Sofia, Bulgaria). It is n...

[External quality assessment of drug susceptibility testing for Mycobacterium tuberculosis].

OBJECTIVE The Committee for Mycobacterial Examinations has planned and implemented the third external quality assessment of drug susceptibility testing for Mycobacterium tuberculosis to the hospital and private laboratories. METHOD The Committee delivered 20 M. tuberculosis strains, exactly pairs of 10 strains, which were evaluated and standardized for the drug resistance pattern in the WHO/ ...
