Abstract

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-P2143T 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-P2143T 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-P2143T is compared with closely related species, the values ranged from 71.23% with A. hydrogenalis strain DSM 7454T (NZ_ABXA01000052.1) to 90.64% with A. provencensis strain 9402080T (NZ_HG003688.1). This strain has implemented the repertoire of known bacteria of the human urinary tract.

Highlights

  • The genus Anaerococcus belonging to the phylum Firmicutes, was first described in ­20011

  • Through a taxono-genomics s­ trategy[15], the description of Anaerococcus urinimassiliensis strain Marseille-P2143 (= Collection des Souches de l’Unité des Rickettsies (CSUR) P2143 = DSM 103,473), a new bacterium isolated from the urine of a young boy affected by autoimmune hepatitis associated with membranoproliferative glomerulonephritis, and classified into Peptoniphilaceae family

  • In 2015, we isolated in the urine of a 17-year-old boy with autoimmune hepatitis and membranoproliferative glomerulonephritis, a bacterial strain belonging to the genus Anaerococcus that could not be identified at the species level

Summary

Introduction

The genus Anaerococcus belonging to the phylum Firmicutes, was first described in ­20011 Members of this bacterial genus are mainly anaerobic gram-positive c­ occi[2]. Through a taxono-genomics s­ trategy[15], the description of Anaerococcus urinimassiliensis strain Marseille-P2143 (= CSUR P2143 = DSM 103,473), a new bacterium isolated from the urine of a young boy affected by autoimmune hepatitis associated with membranoproliferative glomerulonephritis, and classified into Peptoniphilaceae family. This new bacterial species was shortly described in a new species announcement in ­201616
