Growth of oral Streptococcus species and Actinomyces viscosus in human saliva.

Microorganisms in dental plaque live in constant association with saliva. The role of saliva in the adherence of bacteria to the teeth and the antibacterial properties of saliva have been well investigated; less interest has been shown in the possible role of saliva as a substrate for oral microorganisms. In this study it was shown that saliva can serve as a growth medium for oral Streptococcus...

Establishment and distribution of Actinomyces viscosus and Actinomyces naeslundii in the human oral cavity.

The intraoral establishment and proportional distribution of suspected periodontal pathogens Actinomyces viscosus and Actinomyces naeslundii were studied using a recently developed differential plating medium, CNAC-20. Saliva and dental plaque samples were collected from 108 subjects ranging in age from infants to young adults; tongue and buccal mucosa samples were collected from only the adult...

Interbacterial adherence between Actinomyces viscosus and strains of Streptococcus pyogenes, Streptococcus agalactiae, and Pseudomonas aeruginosa.

Interbacterial adherence was sought between strains of Actinomyces viscosus indigenous to the human mouth and strains of Streptococcus pyogenes, Streptococcus agalactiae, and Pseudomonas aeruginosa. Six of nine strains of S. pyogenes, three of five strains of S. agalactiae, and two of four strains of P. aeruginosa were found to coaggregate with each of five strains of A. viscosus tested. Some c...

Comparison of Antimicrobial Effects of Matrica Herbal Mouthwash and 0.2% Chlorhexidine on the Growth of Streptococcus Mutans, Actinomyces Viscosus, and Enterobacter Cloacae: A Short Report

Background and Objectives: Mouthwashes are commonly used to reduce the harmful effects of oral bacteria. The purpose of the present study was to compare the antibacterial effects of Matrica and Chlorhexidine 0.2% mouthwashes on common microorganisms in periodontal diseases. Materials and Methods: This is a laboratory study in which disc diffusion method was used. The diameter of the inhibition...

Mannose-contaminating agglutinin for Actinomyces viscosus and Actinomyces naeslundii.

Rapid agglutination of Actinomyces viscosus and Actinomyces naeslundii cells by D-mannose solutions was observed during studies of their attachment to mammalian cells in vitro. The specificity of the agglutination reaction was studied by slide agglutination tests and by measuring the rate of decrease in optical density of bacterial phosphate buffer suspensions caused by the setting of bacterial...
