sp. nov., isolated from the female reproductive tract Open Access

Abstract

A novel strain of the genus , named AMBV1719, was isolated from the vagina of a healthy participant in our large-scale citizen science project on the female microbiome, named Isala. Phylogenetic analysis showed that the 16S rRNA gene of AMBV1719 is most similar to that of with a sequence similarity of 99.873 %. However, a genome-wide comparison using average nucleotide identity (ANI) revealed that isolate AMBV1719 showed the highest ANI with JCM 5343, with a value of only 88.17 %. This low ANI value with the most closely related strains known to date indicated that AMBV1719 represents a distinct species. This strain has a limited ability to degrade carbon sources compared to , indicating its adaptation to the host. Its genome has a length of 2.12 Mb with a G+C content of 34.8 mol%. We thus propose the name sp. nov. for this novel species, with AMBV1719 (=LMG 32886=CECT 30756) as the type strain.
