Coaggregation of Bacteroides gingivalis and other black-pigmented bacteroides with several oral bacteria was studied with "reagent" strains specially prepared by methods that have been described previously. B. gingivalis coaggregated with Veillonella, Capnocytophaga and Actinomyces spp., but not with any Streptococcus spp. Coaggregation of B. gingivalis with other bacteria was inhibited and reversed by lactose. Of the asaccharolytic black-pigmented bacteroides, only B. gingivalis demonstrated any coaggregation with other bacteria, whereas within the saccharolytic species, B. loescheii showed a marked ability to coaggregate with several species of oral bacteria. This property of coaggregation by B. gingivalis may be an important factor in the pathogenesis of periodontal infections.
利用先前已描述的方法制备的“试剂”菌株，研究了牙龈卟啉单胞菌与其他产黑色素类杆菌以及几种口腔细菌的共聚作用。牙龈卟啉单胞菌与韦荣球菌属、二氧化碳嗜纤维菌属和放线菌属发生共聚，但不与任何链球菌属发生共聚。乳糖可抑制并逆转牙龈卟啉单胞菌与其他细菌的共聚作用。在不分解糖的产黑色素类杆菌中，只有牙龈卟啉单胞菌表现出与其他细菌的共聚作用，而在分解糖的菌种中，洛氏卟啉单胞菌表现出与几种口腔细菌显著的共聚能力。牙龈卟啉单胞菌的这种共聚特性可能是牙周感染发病机制中的一个重要因素。
