Question

In a disc diffusion assay, the zone of inhibition will be ___for organisms more resistant to an antimicrobial agent. absent smaller larger yellow

Answer 1

Answer :- Smaller.

Explanation :- The zone of inhibition is a area in a microbiological culture medium or a microbiological plates around the region of antibiotic in which the bacterial colonies don't grow.

It is basically used to to find out the capacity of a microorganisms resistancy or susceptibility towards antimicrobial agent.

Antimicrobial agents are those which basically stops the growth of organism.

Here according to the quiestion the organism is more resistant to antimicrobial agent i.e the antimicrobial agent can't affect the growth of that particular organisms. Therefore the growth of micrograms is smooth or fluent in this case.

So we know that the zone of inhibition is inversely proportional to the capacity of organisms resistancy towards the antimicrobial agent.

As because the organisms here more resistant to antimicrobial agent thus the zone of inhibition is smaller.
