<h3>What are antibiotics?</h3>

Antibiotics are drugs that have the capacity to either inhibit the growth of or kill bacteria and some other microorganisms capable of causing diseases.

Antibiotics are of 2 types:

Narrow spectrum antibiotics
Broad spectrum antibiotics

Narrow spectrum antibiotics are effective against a very narrow range of bacteria. They are very specific in their targets.

Broad spectrum antibiotics, on the other hand, are effective against a broad range of bacteria. They can be referred to as multipurpose antibiotics. They do not only eliminate target pathogenic bacteria.
