Anaerococcus urinimassiliensis sp. nov., a new bacterium isolated from human urine

To date there are thirteen species validly assigned to the genus Anaerococcus. Most of the species in this genus are anaerobic and of human origin. Anaerococcus urinimassiliensis sp. nov., strain Marseille-P2143(T) is member of family Peptoniphilaceae, which was isolated from the urine of a 17-year-old boy affected by autoimmune hepatitis and membranoproliferative glomerulonephritis using the culturomic approach. In the current study, a taxono-genomics method was employed to describe this new species. The strain Marseille-P2143(T) was gram positive cocci with translucent colonies on blood agar. Its genome was 2,189,509 bp long with a 33.5 mol% G + C content and exhibited 98.48% 16S rRNA similarity with Anaerococcus provencensis strain 9,402,080. When Anaerococcus urinomassiliensis strain Marseill-P2143(T) is compared with closely related species, the values ranged from 71.23% with A. hydrogenalis strain DSM 7454(T) (NZ_ABXA01000052.1) to 90.64% with A. provencensis strain 9402080(T) (NZ_HG003688.1). This strain has implemented the repertoire of known bacteria of the human urinary tract.
