How are antibiotics classified?
How are antibiotics classified?
Antibiotics are grouped based on their source (natural, semi-synthetic, or synthetic), chemical makeup, effectiveness against specific bacteria (spectrum of activity), and how they fight bacteria (mode of action).
What is an example of a natural antibiotic?
What is an example of a natural antibiotic?
Penicillin, produced by a fungus, is a prime example of a natural antibiotic.
What are semi-synthetic antibiotics?
What are semi-synthetic antibiotics?
Semi-synthetic antibiotics are made by modifying natural antibiotics in a lab. This creates new versions with improved properties.

Study Notes
Antibiotic Classification
- Antibiotics can be classified into three categories: natural, semi-synthetic, and synthetic antibiotics.
Natural Antibiotics
- Natural antibiotics are derived from microorganisms, such as bacteria and fungi.
- An example of a natural antibiotic of fungal origin is penicillin.
Semi-Synthetic Antibiotics
- Semi-synthetic antibiotics are derived from natural antibiotics through chemical modification.
- They are created by modifying the structure of natural antibiotics to enhance their effectiveness and stability.
Synthetic Antibiotics
- Synthetic antibiotics are produced entirely through a synthetic process.
- They are created in a laboratory using chemical reactions and do not occur naturally.
Bacteriostatic vs. Bactericidal Antibiotics
- Bacteriostatic antibiotics inhibit the growth of bacteria, preventing them from multiplying.
- Bactericidal antibiotics kill bacteria directly.
- The primary difference between bacteriostatic and bactericidal antibiotics is their mechanism of action, with bacteriostatic antibiotics only inhibiting growth and bactericidal antibiotics causing bacterial death.
