Which of the following is not regarded as antibiotic in true sense?
- A. Tetracycline
- B. Penicillin
- C. Sulpha drugs
- D. chloramphenicol
Step-by-step solution
Antibiotics in the true sense are substances produced by microorganisms that inhibit or kill other microorganisms. Penicillin (from fungi), tetracycline (from bacteria), and chloramphenicol (from bacteria) are natural or semi-synthetic antibiotics. Sulpha drugs (sulfonamides) are entirely synthetic antimicrobial agents and are not derived from natural microbial sources, so they are not regarded as antibiotics in the true sense.
