Actinomyces viscosus

Chlorhexidine (C) is generally effective against all bacteria, but Streptococcus mutans and Actinomyces viscosus, two bacteria particularly associated with dental lesions, are especially susceptible to its action. Stannous fluoride (D) is widely used in caries prevention, and many studies have proven its effectiveness.

Evidence for a horizontal sialidase gene transfer between bacteria has been obtained by comparison of the similarities of bacterial sialidases so far sequenced [246,660,768,799]. It was found that some of the sialidases are related in accordance with the phylogenetic distances of their producers, e.g. Micromonospora viridifaciens and Actinomyces viscosus...

The maximum production of the D-fructan, levan, has been shown to occur during the mid-exponential to the late exponential phase of growth of Actinomyces viscosus and is followed by a rapid decline as a result of the production of levan hydrolase activity.The levan produced by Streptococcus mutans OMZ 176 appears to have a structure similar to other known D-fructans and inulin. On the basis of chemical shift displacements of the n.m.r. spectra, resulting from 0-substitution at specific carbon atoms, resonances have been assigned to the carbon atoms of the j3-D-fructofuranosyl residues in levans. A variety of different levans show almost identical n.m.r. spectra in contrast to a wide divergence in the corresponding spectra of dextrans. ...
