Abstract

Ten strains, BG-AF3-A, pH52_RY, WF-MT5-A, BG-MG3-A, Lr3000, RRLNB_1_1, STM3_1, STM2_1, WF-MO7-1 and WF-MA3-C, were isolated from intestinal or faecal samples of rodents, pheasant and primate. 16S rRNA gene analysis identified them as . However, average nucleotide identity and digital DNA–DNA hybridization values based on whole genomes were below 95 and 70 %, respectively, and thus below the threshold levels for bacterial species delineation. Based on genomic, chemotaxonomic and morphological analyses, we propose five novel species with the names sp. nov. (type strain BG-AF3-A=DSM 110574=LMG 31633), sp. nov. (type strain WF-MT5-A=DSM 110569=LMG 31629), sp. nov. (type strain Lr3000=DSM 110573=LMG 31632), sp. nov. (type strain STM3_1=DSM 110572=LMG 31631) and sp. nov. (type strain WF-MO7-1=DSM 110576=LMG 31630). Core genome phylogeny and experimental evidence of host adaptation of strains of further provide a strong rationale to consider a number of distinct lineages within this species as subspecies. Here we propose six subspecies of : subsp. subsp. nov. (type strain AP3=DSM 110703=LMG 31724), subsp. subsp. nov. (type strain 3c6=DSM 110571=LMG 31635), subsp. subsp. nov. (type strain lpuph1=DSM 110570=LMG 31634), subsp. subsp. nov. (type strain F 275=DSM 20016=ATCC 23272), subsp. subsp. nov. (type strain 1063=ATCC 53608=LMG 31752) and subsp. subsp. nov. (type strain 100-23=DSM 17509=CIP 109821).
