RESUMO

We evaluated the routinely application of an automated system(STAM) and the conventional method (STPM), used to determine the profile of sensitivity to antimycobacterial drugs of 126 clinical isolates of the complex M. tuberculosis. Clinical isolates was group divided into: without treatment (WT), previously treated (PT) and multidrug resistant (MDR).Concordant result between STPM and STAM, for Rifampin, in WT, was 98.3%, p=1.000 and Kappa=0.659. PT, was 94.3%, p=0.625 and Kappa=0.639; in MDR, was 96.6%, p=0.625 and Kappa=0.651. For Hidrazin, WT, was 88.5%, p=0.125 and Kappa=0.408; in PT, 88.6%, p=0.625 and Kappa=0.645; for MDR, 86.7%, p=0.625 and Kappa=0.053. For Streptomycin, PT was 93.5%, p=0.125 and Kappa=0.635. In PT, was 79,5%, p=0.016 and Kappa=0.296; in MDR, 76.6%, p=0.453 and Kappa=0.533. For Ethambutol, WT was 93.4%, p=0.125; in PT 94.3%, p=0.500 and Kappa=0.478. MDR was 72.4%, p=0.70 and kappa=0.455. Evaluation of mycobacterial sensitivity was faster in the automated method when compared with the conventional method.
