It was recently proposed that the genus Bacteroides should be restricted to Bacteroides fragilis (the type species) and closely related organisms (viz., B. caccae, B. distasonis, B. eggerthii, B. merdae, B. ovatus, B. stercoris, B. thetaiotaomicron, B. uniformis, and B. vulgatus). By contrast, the moderately saccharolytic, predominantly oral Bacteroides species, which include B. melaninogenicus, B. oralis, and related species, form a phenotypically and phylogenetically coherent group of species which differ so significantly from the emended description of the genus Bacteroides that they should not be classified in the same genus. Therefore, we formally propose that these species be reclassified in a new genus, Prevotella. The type species is Prevotella melaninogenica.
最近有人提议，拟杆菌属应仅限于脆弱拟杆菌（模式种）及与之密切相关的生物体（即粪拟杆菌、解脲拟杆菌、埃氏拟杆菌、屎拟杆菌、卵形拟杆菌、硬结拟杆菌、多形拟杆菌、单形拟杆菌和普通拟杆菌）。相比之下，中度糖化、主要存在于口腔中的拟杆菌物种，包括产黑色素拟杆菌、口腔拟杆菌及相关物种，形成了一个表型和系统发育上连贯的物种群，它们与修订后的拟杆菌属描述差异极大，不应归为同一属。因此，我们正式提议将这些物种重新分类到一个新属——普雷沃菌属。模式种是产黑色素普雷沃菌。
