Question

Quizplus · Accepted Answer

M. tuberculosis is known to produce urease, which can be detected using a urease test. While urea accumulation may occur during tuberculosis, it is not a specific sign of the disease. The reduction of nitrate ion is not relevant to the identification of M. tuberculosis. M. bovis can also cause tuberculosis, but the urease test is specifically used to identify M. tuberculosis.
