Abstract

A total of 80 oral strains of Bacteroides gingivalis, B. asaccharolyticus, B. melaninogenicus subsp. intermedius, B. melaninogenicus subsp. melaninogenicus, Capnocytophaga, Treponema denticola, and T. vincentii were characterized with the API ZYM system for 19 enzyme activities. Comparison of anaerobic and aerobic incubation with nine reference strains of these organisms showed no important differences. The key differential tests for black-pigmented Bacteroides strains and treponemes of oral origin were trypsin, alpha-glucosidase, and N-acetyl-beta-glucosaminidase. All Capnocytophaga strains produced distinctive aminopeptidase activities but varied in their glycosidic capabilities. The presence of a trypsin-like activity in B. gingivalis, T. denticola, and a group of Capnocytophaga strains may contribute to tissue destruction in periodontal disease.

摘要

总共80株牙龈拟杆菌、解糖拟杆菌、中间型产黑色素拟杆菌、产黑色素产黑色素拟杆菌、二氧化碳嗜纤维菌、具核梭杆菌和文森氏梭杆菌用API ZYM系统对19种酶活性进行了鉴定。这些微生物的9株参考菌株在厌氧和好氧培养条件下的比较显示没有重要差异。对口腔来源的产黑色素拟杆菌菌株和密螺旋体的关键鉴别试验是胰蛋白酶、α-葡萄糖苷酶和N-乙酰-β-葡萄糖胺酶。所有二氧化碳嗜纤维菌菌株都产生独特的氨肽酶活性,但糖苷酶能力各不相同。牙龈拟杆菌、具核梭杆菌和一组二氧化碳嗜纤维菌菌株中存在类胰蛋白酶活性可能导致牙周病中的组织破坏。
