Which method is the least effective in eliminating microorganisms causing tuberculosis?

Cleaning with an antiseptic is often used to reduce or eliminate the presence of microorganisms on surfaces and skin. However, when it comes to specifically targeting the bacteria that cause tuberculosis (TB), antiseptics may lack the necessary potency. Tuberculosis is caused by Mycobacterium tuberculosis, which has a waxy cell wall that makes it more resistant to many common antiseptics.

In contrast, using hot water can help to remove germs effectively, especially when combined with detergent, and washing hands thoroughly is one of the best practices for preventing the spread of TB and other infections. Not sharing personal items also reduces the risk of transmitting infectious agents, making it a preventive measure.

Thus, while antiseptics can aid in infection control, they may not be the most effective method for combating the specific microorganisms that cause tuberculosis, highlighting why this method ranks lower in effectiveness against such resilient pathogens.
