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...
متن کاملDifferential medium for detecting dental plaque bacteria resembling Actinomyces viscosus and Actinomyces naeslundii.
A medium for detecting colonies of Actinomyces viscosus and Actinomyces naeslundii in dental plaque samples was developed. The medium (CNAC-20) contains 20.0 mug of 3CdSO4-8H2O per ml of Columbia CNA agar base. Laboratory strains of A. viscosus grew on CNAC-20 in characteristic round, white, smooth, opaque colonies. Increasing the cadmium concentration impaired the growth of some A. viscosus st...
متن کاملDevelopment of a selective medium for detection and enumeration of Actinomyces viscosus and Actinomyces naeslundii in dental plaque.
A selective medium (CFAT) was developed for the detection and enumeration of Actinomyces viscosus and Actinomyces naeslundii in dental plaque. Neutral acriflavin and potassium tellurite were used in combination with the known selective agents cadmium and fluoride to eliminate most of the competing plaque flora. Composition of CFAT per liter was as follows: Trypticase soy broth (BBL Microbiology...
متن کاملEstablishment 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...
متن کاملImmune labeling of certain strains of Actinomyces naeslundii and Actinomyces viscosus by fluorescence and electron microscopy.
A total of 12 well-characterized strains of Actinomyces viscosus and A. naeslundii grown on Trypticase soy agar plates supplemented with sheep erythrocytes were examined by light microscopy and transmission electron microscopy after treatment with appropriately labeled antisera to homologous and heterologous strains. Cells incubated with homologous rabbit antisera followed by fluorescein-isothi...
