Question

Identify the correct set from the following.

• A. Penicillin – narrow spectrum - bacteriostatic
• B. Chloramphenicol – broad spectrum - bacteriostatic
• C. Ampicillin – narrow spectrum - bactericidal
• D. Ofloxacin – broad spectrum - bacteriostatic

Hint:

Broad-spectrum antibiotics target multiple bacterial strains, while narrow-spectrum antibiotics are more specific.

Answer 1

The Correct Option is B

Step 1: Understanding Bacterial Action
- Bacteriostatic drugs inhibit bacterial growth but do not kill them.
- Bactericidal drugs kill bacteria directly. Step 2: Checking the Options
- Penicillin is narrow-spectrum but is bactericidal, not bacteriostatic.
- Chloramphenicol is broad-spectrum and inhibits bacterial protein synthesis, making it bacteriostatic.
- Ampicillin is a broad-spectrum antibiotic, not narrow-spectrum.
- Ofloxacin is a fluoroquinolone, and it is bactericidal, not bacteriostatic.
