Characterization of Bacteroides asaccharolyticus and B. melaninogenicus oral isolates.
Experiments were designed to characterize a number of oral "pigmented" Bacteroides isolates with regard to their pathogenicity in an experimental model system and a number of other properties. T these include fatty acid determination, hemagglutination studies, collagenase and protease activities, and vitamin K dependency. Oral B, asaccharolyticus and B, melaninogenicus isolates differed from one another in phenylacetic acid production, hemagglutination, collagenase activity, and pathogenicity. All B. asaccharolyticus were found to be pathogenic in the vivo mixed infection model and this property could be correlated with biochemical enzymatic activities.
