Abstract
Five strains of actinomyces isolated from the dental plaque of cattle were assigned presumptively to the genus Actinomyces on the basis of Gram staining, colonial and cellular morphology, fermentation reactions and acid end products of metabolism. This assignment was confirmed by the molar composition of peptidoglycans. The isolates formed a homogeneous group on the basis of the sodium dodecyl sulfate-polyacrylamide electrophoresis patterns of their polypeptides, their cell wall carbohydrate constituents and their DNA mean base compositions. They were also clearly related as determined by DNA-DNA homology, which distinguished them from strains of A. naeslundii, A. viscosus and A. denticolens. A new Taxon, A. howellii, is proposed for these strains, the type strain of which is strain NCTC 11636.This publication has 1 reference indexed in Scilit:
