Effect of biofilm growth on expression of surface proteins of Actinomyces naeslundii genospecies 2.
The predominant surface proteins of biofilm and planktonic Actinomyces naeslundii, a primary colonizer of the tooth surface, were examined. Seventy-nine proteins (the products of 52 genes) were identified in biofilm cells, and 30 of these, including adhesins, chaperones, and stress-response proteins, were significantly up-regulated relative to planktonic cells.
متن کاملComparative pathogenicity of Actinomyces naeslundii and Actinomyces israelii.
Typical actinomycosis has been produced in mice following single intraperitoneal injections of saline suspensions of Actinomyces israelii and A. naeslundii. A. israelii produced infections in 95.8% of the animals inoculated. A. naeslundii, generally considered to be a saprophytic organism, produced lesions in 89.7% of the inoculated animals. The finding that A. naeslundii produced lesions in mi...
متن کاملevaluation of antimicrobial effects of different concentrations of triple antibiotic paste on mature biofilm of enterococcus faecalis
background and aims. triple antibiotic paste (tap) is widely used in endodontics for root canal disinfection, particularly in regenerative procedures. the aim of this in vitro study was to evaluate the antimicrobial effects of different concentrations of tap at 1-, 2-, 3-, and 4-week intervals on mature enterococcus faecalis biofilm. materials and methods. a total of 287 extracted one-rooted hu...
متن کاملMannose-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 کاملActinomyces naeslundii: An Uncommon Cause of Endocarditis
Actinomyces rarely causes endocarditis with 25 well-described cases reported in the literature in the past 75 years. We present a case of prosthetic valve endocarditis (PVE) caused by Actinomyces naeslundii. To our knowledge, this is the first report in the literature of endocarditis due to this organism and the second report of PVE caused by Actinomyces.
