[Adherent mechanism of the mutans of Actinomyces viscosus T14V].
Three mutans of Actionmyces viscous T14V lacking type1 (5951), type 2 (5519) and both types of fimbriae (147) were selected in this study. We compared the ability of their adsorption to the test-tube wall, the result of the cellular coaggregation between these mutant strains and Streptococcus sanguis 34, Streptococcus sanguis black bova, Streptococcus mutans ingbritte, Streptococcus sobrinus 6715 and analysed the chemical characterization of cell walls of the three mutans. We found that the specific fimbriae and cell hydrophobicities had great effect on the bacteria adsorption or coaggregation.
