title: Quantification of the bacterium Bacteroides gingivalis in human dental plaque by detection of the trypsin-like protease activity of colonies imprinted on membrane filters.
abstract: Individual colonies of this organism in primary cultures of human dental plaque were distinguished from colonies of other species of black-pigmented Bacteroides by detection of their trypsin-like proteolytic activity using a specific chromogenic enzyme substrate.
