Question

Many people use antimicrobial soap to kill bacteria on their hands. However, overuse may actually increase the risk of infection. How could this occur?

a) Antimicrobial soap increases bacterial resistance.
b) Antimicrobial soap destroys beneficial bacteria as well.
c) Antimicrobial soap alters the skin's pH balance.
d) Antimicrobial soap causes skin dehydration.

Answer 1

Overuse of antimicrobial soap can increase the risk of infection due to several factors, including bacterial resistance, destruction of beneficial bacteria, and alteration of the skin's pH balance.

Step-by-step explanation:

Overuse of antimicrobial soap may actually increase the risk of infection due to several reasons:

1. Antimicrobial soap increases bacterial resistance: The widespread use of antimicrobial soap can lead to the development of antimicrobial-resistant bacterial strains, making the soap less effective in killing harmful bacteria.
2. Antimicrobial soap destroys beneficial bacteria as well: The soap not only kills harmful bacteria but also eliminates beneficial bacteria that help maintain a healthy balance on the skin. This disruption can allow for the overgrowth of certain species, leading to infection.
3. Antimicrobial soap alters the skin's pH balance: The soap can disrupt the natural pH balance of the skin, which can create an environment that is more conducive to the growth of harmful bacteria.
