    Scientific Reports, 2021
    Co-Authors: Aurelie Morand, E K Yimagou, Issa Isaac Ngom, Mamadou Lamine Tall, Anthony Levasseur, Jean Christophe Lagier, Didier Raoult, F Cornu, Michel Tsimaratos, Pierre-edouard Fournier
    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.

    Abstract:

    Abstract Anaerococcus marasmi sp. nov. strain Marseille-P3557T is a new species isolated from a stool of a Nigerian child with marasmus. The genome of Marseille-P3557T was 2,130,060 bp-long (35.4% G+C content). The closest species based on 16S rRNA sequence was Anaerococcus prevotii strain 20548 with 97.6% sequence similarity. Considering phenotypic features and comparative genome studies, we proposed the strain Marseille-P3557T as the type strain of Anaerococcus marasmi sp. nov. a new species within the genus Anaerococcus.

  • 'Anaerococcus mediterraneensis' sp. nov., a new species isolated from human female genital tract.

    Abstract:

    We report the principal characteristics of ‘Anaerococcus mediterraneensis’ strain Marseille P2765, a new member of the Anaerococcus genus. Strain Marseille P2765 was isolated in a vaginal sample of a 26-year-old patient with bacterial vaginosis.

    Co-Authors: Pierre-edouard Fournier, Jean Christophe Lagier, Aurelie Morand, F Cornu, Michel Tsimaratos, Frederic Cadoret
    Abstract:

    We report the main characteristics of 'Anaerococcus urinomassiliensis' strain FC4(T) (CSURP2143) that was isolated from a urine sample of a 17-year-old boy affected by autoimmune hepatitis and membranoproliferative glomerulonephritis.

  • Anaerococcus rubiinfantis sp nov., isolated from the gut microbiota of a Senegalese infant with severe acute malnutrition
    Anaerobe, 2016
    Co-Authors: Maryam Tidjani Alou, Pierre-edouard Fournier, Saber Khelaifia, Caroline Michelle, Claudia Andrieu, Nicholas Armstrong, Fadi Bittar, Cheikh Sokhna, Aldiouma Diallo, Didier Raoult
    Abstract:

    Anaerococcus rubiinfantis sp. nov. strain mt16(T) is a new species within the genus Anaerococcus, which was isolated by the culturomics approach from the gut microbiota of an infant suffering from kwashiorkor. A phenotypic, biochemical and proteomic description of this strain is hereby presented alongside a complete annotation of its genome. This strictly anaerobic species forms Gram-positive non-sporeforming cocci. The major fatty acid was hexadecanoic acid. The phylogenetic analysis of strain mt16(T) showed a 97.9% similarity level with Anaerococcus vaginalis, the closest validly published species. Its genome is 1,929,161 bp long with 29.5% G + C content and contains 1808 protein-coding genes and 56 RNA genes, among which are six rRNA genes. Genomic analysis identified 41/1864 coding genes as ORFans (2.2%) and at least 620/1808 (34.9%) orthologous proteins which are not shared with the closest phylogenetic species. We believe that the extension of the human anaerobic gut compendium by culturomics is one of the first steps that will improve the understanding of the links between the microbiome and health or disease.

  • Anaerococcus nagyae sp nov isolated from human clinical specimens
    Anaerobe, 2016
    Co-Authors: Alida Veloo, E D De Vries, Helene Jeanpierre, Van Arie Winkelhoff
    Abstract:

    We describe a new Anaerococcus species isolated from human clinical specimens. Analyses of 16S rRNA gene sequences of three strains showed <98% similarity with its closest relative Anaerococcus octavius. Phylogenetically the isolated strains form a cluster and can be differentiated from other species of the genus Anaerococcus based on its phenotypic characteristics and its MALDI-TOF MS profile. We propose the name Anaerococcus nagyae, with A. nagyae DSM101193 (accession number KU043522) as the type strain.

  • Anaerococcus degenerii sp. nov., isolated from human clinical specimens
    Anaerobe, 2015
    Co-Authors: Alida Veloo, P. E. Elgersma, Van Arie Winkelhoff
    Abstract:

    Four clinical isolates of gram-positive strict anaerobic cocci were isolated from four different human mixed anaerobic infections. The taxonomical status of the four strains could not be established using standard identification techniques. The biochemical features of the strains were established and their taxonomic position was determined using 16S rRNA sequencing. The four strains form a homogeneous phenotypical and genotypical cluster. A new Anaerococcus species is proposed for these isolates: Anaerococcus degenerii sp. nov. The type strain is UMCG-104(T) = DSM29674(T) (accession number AM176528). (C) 2015 Elsevier Ltd. All rights reserved.

  • identification of gram positive anaerobic cocci by maldi tof mass spectrometry
    Systematic and Applied Microbiology, 2011
    Co-Authors: Alida Veloo, Marcel Erhard, Martin Welker, G W Welling, John E Degener
    Abstract:

    Gram-positive anaerobic cocci (GPAC) are part of the commensal microbiota of humans and are a phylogenetically heterogeneous group of organisms. To evaluate the suitability of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) for the identification of GPAC, a database was constructed, using reference strains of commonly encountered GPAC and clinical isolates of which the sequence of the 16S rRNA gene was determined. Subsequently, the database was validated by identifying 107 clinical isolates of GPAC. Results were compared with the identifications obtained by 16S sequencing or fluorescent in situ hybridization (FISH). Strains belonging to the same species grouped together, in most cases, by MALDI-TOF MS analyses. Strains with sequence similarities less than 98% to their closest relatives, formed clusters distinct from recognized species in the MALDI-TOF MS dendrogram and, therefore could not be identified. These strains probably represent new species. Only three clinical isolates (2 strains of Finegoldia magna and 1 strain of Anaerococcus vaginalis) could not be identified. For all the other GPAC strains (96/107), reliable identifications were obtained. Therefore, we concluded that MALDI-TOF MS is an excellent tool for the identification of phylogenetically heterogeneous groups of micro-organisms such as GPAC.
