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.
However, there is not always a precise distinction between them and bactericidal antibiotics; high concentrations of some bacteriostatic agents are also bactericidal, whereas low concentrations of some bacteriocidal agents are bacteriostatic.hen bacteriostatic antimicrobials are used, the duration of therapy must be sufficient to allow host defense mechanisms to eradicate the bacteria.
