Antibacterial activity of Lactoferrin and Lactoferricin against oral Streptococci
Lactoferrin (Lf) is an iron-binding glycoprotein which exhibits antibacterial activity against a broad range of Gram-negative and Gram-positive bacteria. The mechanisms of this property are complex and involve iron sequestration as well as direct interaction with bacteria. Lactoferricin (LFcin), a Lf-derived peptide released by pepsin digestion of lactoferrin, is a more potent antibacterial com...
متن کاملActivity of Synthetic Antimicrobial Peptide GH12 against Oral Streptococci.
Controlling the growth of cariogenic microorganisms such as oral streptococci is an adjunct therapy for caries-active individuals to prevent and treat caries. Here we investigated the antimicrobial activity of the synthetic amphipathic α- helical antimicrobial peptide GH12 (GLLWHLLHHLLH-NH2) against oral streptococci in vitro. Circular dichroism studies showed that GH12 takes on an α-helical co...
متن کاملStress Responses of Oral Streptococci
To persist in the oral cavity, bacteria must be able to tolerate rapid and substantial environmental fluctuations, particularly in pH and nutrient source and availability. Various species of Streptococcus, one of the most abundant genera in the mouth, are associated with oral health, as well as with dental caries. Cariogenic streptococci depend on a biofilm lifestyle for survival and persistenc...
متن کاملEvaluation of the antimicrobial effects of extract of Zataria multiflora against oral Streptococci
Dental caries is the most common chronic disease which involve the civilized humankind and is designated as the “disease of the civilization”. Oral Streptococci such as S. sanguis, S. salivarius and S. mutans have a very important role to play in the process of plaque formation. In order to inhibit and control caries process, the growth of such Streptococci must be reined. The purpose of this s...
متن کاملOral streptococci... products of their environment.
Microbial biofilms form on oral surfaces. These biofilms usually exist in dynamic equilibria with host defenses and are compatible with maintenance of the integrity of the target tissues. Disease occurs when the composition and the metabolic activities of complex communities in biofilms are perturbed. These ecologically driven changes in oral biofilms result in increases in the proportions of p...
