Formation of extracellular lipoteichoic acid by oral streptococci and lactobacilli.
Examination of the culture fluids from a number of strains of oral streptococci and latobacilli has shown the presence of an erythrocyte-sensitizing antigen with the properties of lipoteichoic acid. The antigen was isolated from the culture fluids of Lactobacillus casei and Lactobacillus fermentum and characterized chemically and serologically, For other strains, serological evidence for the pr...
متن کاملGrowth inhibition of oral mutans streptococci and candida by commercial probiotic lactobacilli - an in vitro study
BACKGROUND Probiotic bacteria are suggested to play a role in the maintenance of oral health. Such health promoting bacteria are added to different commercial probiotic products. The aim of the study was to investigate the ability of a selection of lactobacilli strains, used in commercially available probiotic products, to inhibit growth of oral mutans streptococci and C. albicans in vitro. M...
متن کاملInhibition of transformation of streptococci by antibodies.
It has been reported (Nava, Galis, and Beiser, Nature 197:903, 1963) that immunization of rabbits with competent pneumococci stimulates the production of antibodies which inhibit transformation. Similar data reported below show that the antigenic structure of transformable streptococci in the competent state differs from the antigenic structure of cells in the noncompetent state. Competence in ...
متن کاملEcology of human oral lactobacilli.
Lactobacilli were found in saliva, on teeth, and on the dorsum of the tongue, the vestibular mucosa, and the hard palate in humans. Their proportions in saliva, expressed as percentage of the anaerobically cultivable flora, were 10- to 100-fold higher than those on the tooth surface, but were comparable to those on the epithelial surfaces. The adherence of Lactobacillus casei and L. fermenti to...
