Which of the following is NOT a bactericidal antibiotic?
Penicilin
Amioglycosiole
0.03 ppm Cl2
Ofloxacin
The antibiotics can either be bactericidal or bacteriostatic.
Bactericidal: The drugs which kill the organism in the body. For example, penicillin, ofloxacin, and aminoglycosides.
0.03 ppm Cl2 is a disinfectant, not a Bactericidal antibiotic.
So, option 3 is correct.
