“…, Prevotella intermedia/Prevotella nigrescens , Fusobacterium sp., members of the “orange complex”, are also related to periodontal breakdown as the secondary group of periodontal pathogens and the “green complex,” represented by the combination of Eikenella corrodens , Capnocytophaga sputigena, C. ochracea, C. gingivalis, C. concisus was considered primary colonizers and compatible with periodontal health 26
