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...
متن کاملEvaluation of BACTEC 460 TB system for measurement of in vitro anti-Mycobacterium leprae activity of various antimicrobials.
In vitro anti-leprosy activities of various antimicrobials were measured by using the BACTEC 460 TB System. The Growth Index reducing activities of test drugs were strong in clofazimine, KRM-1648, rifabutin, clarithromycin and rifampicin; intermediate in sparfloxacin, minocycline and ofloxacin; and weak in ciprofloxacin, fleroxacin and DDS. Amikacin, pipemidic acid, enoxacin and norfloxacin had...
متن کاملValidation of the use of Middlebrook 7H10 agar, BACTEC MGIT 960, and BACTEC 460 12B media for testing the susceptibility of Mycobacterium tuberculosis to levofloxacin.
Levofloxacin, the active l-isomer of the quinolone ofloxacin, is now widely accepted for treatment of multidrug-resistant tuberculosis. Because the drug is now widely used, we sought to establish susceptibility test conditions for Mycobacterium tuberculosis against levofloxacin by the traditional reference method, agar proportion (AP), the commonly used BACTEC 460 radiometric system, and the ne...
متن کاملAntimicrobial susceptibility testing of Mycobacterium tuberculosis to first-line drugs: comparisons of the MGIT 960 and BACTEC 460 systems.
The reliability of the Mycobacteria Growth Indicator Tube (MGIT) 960 system for rapid antimicrobial susceptibility testing (AST) of Mycobacterium tuberculosis was evaluated. Forty-seven isolates, including 10 fully susceptible and 37 resistant strains, were tested for susceptibility to the critical concentrations of streptomycin (STR), isoniazid (INH), rifampin (RMP), and ethambutol (EMB), as r...
متن کاملTesting of susceptibility of Mycobacterium tuberculosis to pyrazinamide with the nonradiometric BACTEC MGIT 960 system.
The reliability of the novel BACTEC MGIT 960 pyrazinamide (PZA) kit (Becton Dickinson Microbiology Systems, Sparks, Md.) was assessed for testing of susceptibility of Mycobacterium tuberculosis to PZA. Results generated by the BACTEC MGIT 960 system (Becton Dickinson) were compared with those obtained with the BACTEC 460TB system. Extensive proficiency testing (phase I) and reproducibility test...
