Tuberculocidal disinfectants kill which bacteria?

• A. The bacteria that causes tuberculosis
• B. The bacteria that causes strep throat
• C. The bacteria that causes MRSA
• D. The bacteria that causes tetanus

Answer: (A)

Tuberculocidal disinfectants are defined by their ability to inactivate the organism that causes tuberculosis. Mycobacterium tuberculosis has a waxy, lipid-rich cell wall that makes it unusually resistant to many cleaners, so products labeled tuberculocidal have been validated to kill this specific bacterium under defined testing conditions. That validation is why this type of disinfectant is described as tuberculocidal. So the bacteria targeted by tuberculocidal disinfectants is the one that causes tuberculosis. The other bacteria listed—those that cause strep throat, MRSA infections, and tetanus—are different pathogens and are not the primary organism these products are validated to kill, though some tuberculocidal formulations may also be effective against them.
