Reclassification of Flexibacter tractuosus (Lewin 1969) Leadbetter 1974 and 'Microscilla sericea' Lewin 1969 in the genus Marivirga gen. nov as Marivirga tractuosa comb. nov and Marivirga sericea nom. rev., comb. nov.

The taxonomic position of the misclassified strains [Flexibacter] tractuosus KCTC 2958(T) and sericea' LMG 13021 was studied using a polyphasic approach. The two strains shared 99.1% 16S rRNA gene sequence similarity and 28% DNA DNA relatedness. On the basis of the phylogenetic evidence supported by genotypic and phenotypic data [Flexibacter] tractuosus KCTC 2958T and [Microscilla] sericea' LMG 13021 are classified as two distinct species in a novel genus, Marivirga, in the family 'Flammeovirgaceae', as Marivirga tractuosa comb. nov. and Marivirga sericea nom. rev., comb. nov., with strains KCTC 2958T (=ATCC 23168(T) =CIP 106410(T) =DSM 4126(T) =NBRC 15989(T) =NCIMB 1408(T) =VKM B-1430(T)) and LMG 13021(T) (=ATCC 23182(T) =NBRC 15983(T) =NCIMB 1403(T)), respectively, as the type strains. The type species is Marivirga tractuosa.
