[The tentative identification of actinomycetes of the oral cavity by a complex of key morphophysiological signs].

In this work the results obtained in the study of the morphology of 208 Actinomyces strains isolated from the oral cavity and a wide spectrum of their enzymatic activity are presented. The identification of these strains was carried out on the basis of chemotaxonomic criteria. Bacteria belonging to the same taxonomic group were found to have considerable similarity in their morphological and physiological features. On the basis of the data obtained in this study a simplified scheme of the tentative identification of fermentative Actinomyces, suitable for use by a wide circle of researchers, is presented.
