A bacteriocide or bactericide is a substance that kills bacteria and, preferably, nothing else.

Bacteriocidal antibiotics kill bacteria: bacteriostatic antibiotics only slow their growth or reproduction.

Penicillin is a bactericide, as are cephalosporins. Aminoglycosidic antibiotics can act in both a bactericidic manner (by disrupting cell wall precursor leading to lysis) or bacteriostatic manner (by binding to 30s ribosomal subunit and reducing translation fidelity leading to inaccurate protein synthesis)

Other bactericidal antibiotics include the fluoroquinolones, nitrofurans, vancomycin, monobactams, co-trimoxazole, and metronidazole.
