<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.
