An antibiotic is a compound, chemical or drug that is produced by a microorganism to inhibit or destroy another microorganism while an antimicrobial agent is a substance inclusive of antibiotics that kills or stops the growth of microorganisms.
Antimicrobials is a group of agents which include antibiotics, antiseptics and anti-fungal agents. Antibiotics are often derived from moulds or are made synthetically .

Antifungal agents are killing or inhibiting the growth of fungi
