RESUMO

In this study, the isolation, characterization, and identification of Bacteroides endodontalis is described. It was found that this asaccharolytic black-pigmented Bacteroides species is associated with infected dental root canals and oral submucous abscesses. B. endodontalis could be differentiated from B. gingivalis by a negative direct hemagglutination test and the absence of trypsin and N-acetyl-beta-glucosamidase. B. endodontalis could be differentiated from B. asaccharolyticus by the absence of alpha-fucosidase, its inability to grow in an atmosphere of 95% N2-5% H2, and a growth requirement for menadione. Immune serum raised against B. endodontalis strain HG 370T agglutinated only B. endodontalis cells. Precautions for the isolation of B. endodontalis are discussed.
