Tuberculocidal disinfectants are specifically proven to kill Mycobacterium tuberculosis, the bacterium that causes tuberculosis. This makes them the most appropriate choice when the target is the TB-causing organism, since TB is more resistant than many other bacteria. In contrast, virucidal products kill viruses, fungicidal products kill fungi, and bactericidal products kill bacteria in general but do not necessarily guarantee effectiveness against the TB bacterium. So the tuberculocidal option is the strongest against the TB organism. Always follow the label for dilution, contact time, and surface suitability.
