Eighty-nine species of subgingival bacteria, represented by 121 reference strains and 892 patient isolates, including gram-negative, gram-positive, aerobic, facultatively anaerobic, microaerophilic, and anaerobic species, were characterized with a panel of fluorogenic, 4-methylumbelliferyl-linked substrate tests. Identifications of all patient isolates were confirmed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of whole-cell proteins relative to reference strains. Characteristic profiles of positive fluorogenic reactions differentiated most of the species, including five Porphyromonas species, six pigmenting and five nonpigmenting Prevotella species, Bacteroides forsythus, three Capnocytophaga species, six Actinomyces species, four Propionibacterium species, and eight Streptococcus species.
