Abstract

In this study, we classified the five strains (ChDC F128T, ChDC F145, ChDC F174, ChDC F206, and ChDC F300) as a novel species of genus Fusobacterium by DNA–DNA hybridization and multi-locus phylogenetic analysis (MLPA), based on a single sequence (24,715 bp) of 22 concatenated housekeeping genes, with morphological and chemotaxonomic characteristics. DNA–DNA hybridization data showed that the values of genomic relatedness between ChDC F128T and each of the other novel strains were ranged from 79.0 to 82.6 %, while those of genomic relatedness between ChDC F128T and type strain of each of subspecies of F. nucleatum or Fusobacterium periodonticum were ranged from 40.9 to 54.4 %. MLPA revealed that the 5 strains were clustered as one group and clearly discriminated with F. nucleatum and F. periodonticum with 100 % bootstrap value. The DNA G+C content of the five novel strains were ranged from 26.9 to 27.0 mol%. The cellular fatty acid analysis of clinical isolates and type strains revealed C14:0, C16:0, and cis-9 C16:1 as the major fatty acids. The cell wall peptidoglycan of the 5 strains was comprised of meso-lanthionine. These results show that the 5 strains are novel species and belong to the genus Fusobacterium. Strain ChDC F128T (=KCOM 1249T = KCTC 5108T = JCM 30218T) is suggested to be the type strain of a novel species of genus Fusobacterium, for which the name Fusobacterium hwasookii sp. nov. is proposed.
