Question

Quizplus · Accepted Answer

Patients infected with Mycobacterium tuberculosis typically need to take antibacterial drugs for six months to ensure complete eradication of the infectious agent. This is due to the slow growth rate of the bacteria and the need for a prolonged treatment course to ensure all bacterial cells have been affected by the drug. In cases where drug resistance is expected, alternate treatment regimens may be necessary, including longer treatment courses or multiple drugs used in combination.
