aesculin/dental caries

Nine strains of anaerobic, non-spore-forming, gram-positive bacilli, isolated from the human oral cavity and provisionally identified as belonging to the genus Eubacterium, were subjected to a comprehensive range of phenotypic and genetic tests. Biochemically, they were found to comprise a

OBJECTIVE To evaluate the hypothesis that food-borne viable Enterococcus faecalis cells could enter the root canal space via coronal leakage. METHODS In a simulated oral environment under mastication the capacity of a calcium sulphate-based temporary filling material (Cavit W) to prevent leakage of

Four bacterial strains isolated from the human oral cavity, PPPA19, PPPA21(T), PPPA28 and PPPA30, were characterized by determining phenotypic and biochemical features, cellular fatty acid profiles and the phylogenetic position based on 16S rRNA gene sequence analysis. 16S rRNA gene sequence

A new serotype (h) of Streptococcus mutans was isolated from the dental plaque of monkeys (Macaca fascicularis). Serotype h strains fermented mannitol and melibiose but not sorbitol or raffinose, failed to hydrolyse aesculin and arginine, did not produce hydrogen peroxide and were unable to grow in
