A 16S rRNA gene sequence divergence of approximately 3 % between the two unknown bacteria and A. finegoldii, as well as distinguishable biochemical characteristics, demonstrates that these organisms are genotypically and phenotypically distinct and that each group represents a previously unknown subline within the genus Alistipes. Chromosomal DNA–DNA reassociation studies further confirmed the separateness of the unidentified bacteria and A. finegoldii. On the basis of the phenotypic and phylogenetic findings, two novel species, Alistipes onderdonkii sp. nov. and Alistipes shahii sp. nov., are proposed. The type strains of A. onderdonkii and A. shahii are WAL 8169T (=CCUG 48946T=ATCC BAA-1178T) and WAL 8301T (=CCUG 48947T=ATCC BAA-1179T), respectively; their DNA G+C contents are 58 and 56 mol%, respectively.", }
