Resazurin microtiter assay plate: simple and inexpensive method for detection of drug resistance in Mycobacterium tuberculosis.
نویسندگان
چکیده
A method for detecting multidrug-resistant Mycobacterium tuberculosis by using a reduction of resazurin is described. Eighty clinical isolates were evaluated against isoniazid and rifampin; results at 7 days were compared with those of the proportion method. Specificity and sensitivity were excellent. The method is simple, inexpensive, and rapid and might be used with other antituberculosis drugs.

Resazurin microtiter assay plate testing of Mycobacterium tuberculosis susceptibilities to second-line drugs: rapid, simple, and inexpensive method.
The emergence of multidrug-resistant tuberculosis calls for new, rapid drug susceptibility tests. We have tested 150 Mycobacterium tuberculosis isolates against the second-line drugs ethionamide, kanamycin, capreomycin, ofloxacin, and para-aminosalicylic acid by the colorimetric resazurin microtiter assay and the proportion method. By visual reading, MICs were obtained after 8 days. A very good...
متن کاملResazurin microtiter assay for detection of drug resistance and determination of critical concentration of cycloserine resistance of Mycobacterium tuberculosis
We evaluated the feasibility of resazurin microtiter assay (REMA) for detecting cycloserine resistance of Mycobacterium tuberculosis. The cutoff value of the critical concentration of cycloserine resistance in vitro about M. tuberculosis isolates was determined innovatively by drawing the receiver operating characteristic (ROC) curve for the first time. The spending time of REMA ranged from 6 t...
متن کاملEvaluation of the resazurin assay for the detection of multidrug-resistant Mycobacterium tuberculosis in Madagascar.
SETTING Multidrug-resistant (MDR) tuberculosis (TB) can jeopardise the success of national TB control programmes. Rapid, simple drug susceptibility tests applicable in developing countries would allow earlier treatment of patients with MDR infections. OBJECTIVE To test the feasibility and performance of the resazurin microtitre assay (REMA) as an indirect test for detecting isoniazid (INH) an...
متن کاملDevelopment of 1,2,4-triazole-5-thione derivatives as potential inhibitors of enoyl acyl carrier protein reductase (InhA) in tuberculosis.
Tuberculosis (TB) ranks second, next to AIDS making it most formidable disease if the present age. One of the crucial enzymes involved in cell wall synthesis of Mycobacterium tuberculosis, InhA (enoyl acyl carrier protein reductase) has been authenticated as an effective target for anti-mycobacterial drug development. In the current work, we have developed novel derivatives of 1,2,4-triazole-5-...
متن کاملApplication of the resazurin microtitre assay for detection of multidrug resistance in Mycobacterium tuberculosis in Algiers.
This study assessed the performance of a rapid, low-cost, colorimetric method, the resazurin microtitre assay (REMA) plate method, for the detection of resistance to isoniazid and rifampicin in 136 clinical isolates of Mycobacterium tuberculosis from two hospitals in Algiers. MICs were determined and the results were compared with those obtained with the conventional proportion method on Löwens...
