A bacteriostatic is a compound which has the effect of preventing bacterial growth. These agents do not kill bacteria like bactericidal compounds; instead, they limit further replication of bacteria at the site where they are introduced. Several antibiotic drugs are bacteriostatic agents, with tetracyclines being a notable example.
Bactericidal antibiotics kill bacteria; bacteriostatic antibiotics slow their growth or reproduction. Antibiotics that inhibit cell wall synthesis: the Beta-lactam antibiotics (penicillin derivatives (penams), cephalosporins (cephems), monobactams, and carbapenems) and vancomycin. Also bactericidal are daptomycin, fluoroquinolones, metronidazole, nitrofurantoin, co-trimoxazole, telithromycin.
