Validation of microscopic observation drug susceptibility testing for rapid, direct rifampicin and isoniazid drug susceptibility testing in patients receiving tuberculosis treatment
Drug susceptibility testing (DST) is often needed in patients clinically failing tuberculosis (TB) therapy. Most studies of phenotypic direct drug susceptibility tests, such as microscopic observation drug susceptibility (MODS) tests, have been performed in patients not receiving TB treatment. The effect of ongoing TB treatment on the performance of MODS direct DST has not been previously explo...
متن کاملPerformance 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...
متن کاملRapid and simple MTT method for rifampicin and isoniazid susceptibility testing of Mycobacterium tuberculosis.
The MTT method for rifampicin and isoniazid susceptibility testing of Mycobacterium tuberculosis was developed by using bacterial suspension prepared from colonies on solid media. The MTT tube assay in 1 ml Middlebrook 7H9 broth was completed within 4 days for rifampicin (RMP) and within 7 days for isoniazid (INH). When MTT assay results with 279 M. tuberculosis clinical isolates were compared ...
متن کاملBlood Agar Validation for Susceptibility Testing of Isoniazid, Rifampicin, Ethambutol, and Streptomycin to Mycobacterium tuberculosis Isolates
In recent studies, it was shown that blood agar can be used at least as effectively as Löwenstein-Jensen medium for growing Mycobacterium tuberculosis. It was also shown that susceptibility testing can be performed on blood agar. Additional validation of blood agar was performed on regional M. tuberculosis isolates from Turkey to determine critical concentrations of isoniazid (INH), rifampicin ...
متن کاملRapid diagnosis of Mycobacterium tuberculosis infection and drug susceptibility testing.
CONTEXT The global control of tuberculosis remains a challenge from the standpoint of diagnosis, detection of drug resistance, and treatment. This is an area of special concern to the health of women and children, particularly in regions of the world with high infant mortality rates and where women have limited access to health care. OBJECTIVE Because treatment can only be initiated when infe...
