Ten strains, BG-AF3-A(T), pH52_RY, WF-MT5-A(T), BG-MG3-A, Lr3000(T), RRLNB_1_1, STM3_1(T), STM2_1, WF-MO7-1(T) and WF-MA3-C, were isolated from intestinal or faecal samples of rodents, pheasant and primate. 16S rRNA gene analysis identified them as Limosilactobacillus reuteri . However, average nucl...

Sumario:Ten strains, BG-AF3-A(T), pH52_RY, WF-MT5-A(T), BG-MG3-A, Lr3000(T), RRLNB_1_1, STM3_1(T), STM2_1, WF-MO7-1(T) and WF-MA3-C, were isolated from intestinal or faecal samples of rodents, pheasant and primate. 16S rRNA gene analysis identified them as Limosilactobacillus reuteri . 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 Limosilactobacillus balticus sp. nov. (type strain BG-AF3-A(T)=DSM 110574(T)=LMG 31633(T)), Limosilactobacillus agrestis sp. nov. (type strain WF-MT5-A(T)=DSM 110569(T)=LMG 31629(T)), Limosilactobacillus albertensis sp. nov. (type strain Lr3000(T)=DSM 110573(T)=LMG 31632(T)), Limosilactobacillus rudii sp. nov. (type strain STM3_1(T)=DSM 110572(T)=LMG 31631(T)) and Limosilactobacillus fastidiosus sp. nov. (type strain WF-MO7-1(T)=DSM 110576(T)=LMG 31630(T)). Core genome phylogeny and experimental evidence of host adaptation of strains of L. reuteri further provide a strong rationale to consider a number of distinct lineages within this species as subspecies. Here we propose six subspecies of L. reuteri : L. reuteri subsp. kinnaridis subsp. nov. (type strain AP3(T)=DSM 110703(T)=LMG 31724(T)), L. reuteri subsp. porcinus subsp. nov. (type strain 3c6(T)=DSM 110571(T)=LMG 31635(T)), L. reuteri subsp. murium subsp. nov. (type strain lpuph1(T)=DSM 110570(T)=LMG 31634(T)), L. reuteri subsp. reuteri subsp. nov. (type strain F 275(T)=DSM 20016(T)=ATCC 23272(T)), L. reuteri subsp. suis subsp. nov. (type strain 1063(T)=ATCC 53608(T)=LMG 31752(T)) and L. reuteri subsp. rodentium subsp. nov. (type strain 100-23(T)=DSM 17509(T)=CIP 109821(T)).
