The two isolates showed 100 % 16S rRNA gene sequence similarity with each other and were most closely related to Prevotella intermedia ATCC 25611T with 96.4 % 16S rRNA gene sequence similarity; the next most closely related strains to the isolates were Prevotella pallens AHN 10371T (96.1 %) and Prevotella falsenii JCM 15124T (95.3 %). Phenotypic and biochemical characteristics of the isolates were the same as those of P. intermedia JCM 12248T, P. falsenii JCM 15124T and Prevotella nigrescens JCM 12250T. The isolates could be differentiated from P. pallens JCM 11140T by mannose fermentation and α-fucosidase activity. Conventional biochemical tests were unable to differentiate the new isolates from P. intermedia, P. falsenii and P. nigrescens. However, hsp60 gene sequence analysis suggested that strain OMA31T was not a representative of P. intermedia, P. pallens, P. falsenii or P. nigrescens. Based on these data, a novel species of the genus Prevotella, Prevotella aurantiaca sp. nov., is proposed, with OMA31T (=JCM 15754T=CCUG 57723T) as the type strain.", }
