Bacteriocins are bioactive peptide complexes (30-60 amino acids) that on other species have a bacteriocidal effect.
Antibacterial drugs are derived from bacteria or molds or are synthesized de novo and can be classified in several ways - bacteriostatic or bacteriocidal, by chemical structure, according to their mode of action, or according to their spectrum of activity.
IL 12 is regarded as a pro-inflammatory cytokine with immunoregulatory function, it may be greatly involved in chronic periodontitis.IL-12 acts not only as an activator of macrophages in the inflammed tissue, increasing their phagocytic and bacteriocidal activity, but also increases the ability of macrophages to produce IL 12 in a powerful positive feedback loop.
(2014) Cell wall-anchored nuclease of Streptococcus sanguinis contributes to escape from neutrophil extracellular trap-mediated bacteriocidal activity.
However, with fermentation of tannin rich plants, their bacteriocidal and bacteriostatic effects on the rumen microbes, and inactivation of their enzymes greatly suppresses fermentation and this could result in decrease of methane production.
(24,25,35,43) Lactobacillus reuteri was found to produce a metabolite called reuterin, which is actually bacteriocidal to many pathogenic bacteria.
In contrast to conventional antibiotics, AMPs appear to be bacteriocidal (bacteria killer) instead of bacteriostatic (bacteria growth inhibitor).
Only 42% (n=90) of dental hygienists identified white spot lesions as incipient caries in enamel, and 60% (n=131) recognized chlorhexidine (CHX) (Peridex; 3M ESPE, Minneapolis, Minn.) as not being bacteriostatic or bacteriocidal to all caries pathogens (Table I).
Loss of cell wall structure causes the bacterial cell to burst (lysis), making penicillin a bacteriocidal antibiotic.
The resistant phenotype was again shown to be inherited since the use of pre-exposed fermentation culture for inoculation of fresh fermentor media with 1% GP indicated absence of initial bacteriocidal effect.
