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.
