sp. nov., sp. nov. and subsp. subsp. nov. isolated from pigs Open Access

Abstract

Three novel strains within the genus (29887, 29892 and 29896) were isolated from healthy pigs during routine veterinary physical exams. All three strains were non-motile and non-spore-forming Gram-positive cocci. The complete genome of each strain was attained, and phylogenetic analyses were performed. Comparison of the genomes of 29887, 29892 and 29896 to the genomes of other strains revealed digital DNA–DNA hybridization (dDDH) values between 21.2% and 53.9% and average nucleotide identity (ANI) values between 70.00% and 94.44%. Phylogenetic analyses suggested that each strain, 29896 ( sp. nov.), 29887 ( sp. nov.) and 29892 ( subsp. subsp. nov.), may represent a novel species within the genus , while ANI analysis indicated that strains 29896 ( sp. nov.) and 29887 ( sp. nov.) represent novel species within the genus and 29892 ( subsp. subsp. nov.) represents a novel subspecies of 29887 ( sp. nov.). Based upon the combined data presented in this study, two novel species, sp. nov. (type strain, 29896=NRRL B-65677=NCTC 14941) and sp. nov. (type strain, 29887=NRRL B-65675=NCTC 14939) are proposed, and one novel subspecies, subsp. subsp. nov. (type strain, 29892=NRRL B-65676=NCTC 14940) is proposed.
