| ABSTRACT Microscopy and bacterial culture are the main tools in the diagnosis of tuberculosis. Since the slow growth of Mycobacterium tuberculosis impairs rapid diagnosis strategies, especially in countries where the latter are the only available resources, the ongoing development of new and inexpensive tools based on mycobacterial metabolism optimizing growth detection with preliminary identification is greatly welcome. When compared to the other species from the M. tuberculosis complex, M. tuberculosis is a strong nitrate reducer. Current assay compares the nitrate reductase activity of M. tuberculosis from pulmonary specimens cultivated in nitrate-supplemented media. Fifty-five sputum samples were decontaminated and inoculated in conventional... |
