The area where bacteria cannot survive because of the antibiotic:

• zone of inhibition

• zone of prohibition

• the friend zone

To inhibit means to stop something.

Inhibition comes from the word "inhibit"

A zone is an area or space

Zone of inhibition is the area or space around the antibiotic where bacteria is not growing.

How many antibiotics does the bacteria seem to be resistant to?
