  • Characterization of the phylogenetic diversity of two novel species belonging to the genus Bifidobacterium: Bifidobacterium cebidarum sp. nov. and Bifidobacterium leontopitheci sp. nov.

    Co-Authors: Sabrina Duranti, Gabriele Andrea Lugli, Alice Viappiani, Leonardo Mancabelli, Giulia Alessandri, Rosaria Anzalone, Giulia Longhi, Christian Milani, Maria Cristina Ossiprandi, Francesca Turroni
    Abstract:

    Two Bifidobacterium strains, i.e., 2176BT and 2177BT, were isolated from Golden-Headed Lion Tamarin (Leontopithecus chrysomelas) and Goeldi's monkey (Callimico goeldii). Isolates were shown to be Gram-positive, non-motile, non-sporulating, facultative anaerobic and d-fructose 6-phosphate phosphoketolase-positive. Phylogenetic analyses based on 16S rRNA sequences, multilocus sequences (including hsp60, rpoB, dnaJ, dnaG and clpC genes) and the core genome revealed that bifidobacterial strains 2176BT and 2177BT exhibit close phylogenetic relatedness to Bifidobacterium felsineum DSM 103139T and Bifidobacterium bifidum LMG 11041T, respectively. Further genotyping based on the genome sequence of the isolated strains combined with phenotypic analyses, clearly show that these strains are distinct from each of the type strains of the so far recognized Bifidobacterium species. Thus, Bifidobacterium cebidarum sp. nov. (2176BT=LMG 31469T=CCUG 73785T) and Bifidobacterium leontopitheci sp. nov. (2177BT=LMG 31471T=CCUG 73786T are proposed as novel Bifidobacterium species.

    Abstract:

    Six Bifidobacterium strains, i.e., Goo31D, Ham19E, Rab10A, Tam1G, Uis4E and Uis1B, were isolated from domestic goose (Anser domesticus), European hamster (Cricetus cricetus), European rabbit (Oryctolagus cuniculus), emperor tamarin (Saguinus imperator) and pygmy marmoset (Callithrix pygmaea). Cells are Gram-positive, non-motile, non-sporulating, facultative anaerobic and fructose 6-phosphate phosphoketolase-positive. Phylogenetic analyses based on 16S rRNA, ITS-, multilocus- sequences and the core genome revealed that bifidobacterial strains Goo31D, Ham19E, Rab10A, Tam1G, Uis4E and Uis1B exhibit close phylogenetic relatedness with Bifidobacterium choerinum LMG 10510, Bifidobacterium hapali DSM 100202, Bifidobacterium saguini DSM 23967 and Bifidobacterium stellenboschense DSM 23968. Genotyping based on the genome sequence of the isolated strains combined with phenotypic analyses, clearly show that these strains are distinct from each of the type strains of the so far recognized Bifidobacterium species. Thus, Bifidobacterium anseris sp. nov. (Goo31D=LMG 30189T=CCUG 70960T), Bifidobacterium criceti sp. nov. (Ham19E=LMG 30188T=CCUG 70962T), Bifidobacterium imperatoris sp. nov. (Tam1G=LMG 30297T=CCUG 70961T), Bifidobacterium italicum sp. nov. (Rab10A=LMG 30187T=CCUG 70963T), Bifidobacterium margollesii sp. nov. (Uis1B=LMG 30296T=CCUG 70959T) and Bifidobacterium parmae sp. nov. (Uis4E=LMG 30295T=CCUG 70964T) are proposed as novel Bifidobacterium species.

    Abstract:

    ABSTRACT Bifidobacterium moukalabense DSM 27321 is the reference strain for a recently described new bifidobacterial species that has been isolated from a wild west lowland gorilla. Here, we report the whole-genome sequence of DSM 27321, which supports very close phylogenetic relatedness with members of the Bifidobacterium adolescentis phylogenetic group and, in particular, the Bifidobacterium dentium taxon.

  • Exploration of the genomic diversity and core genome of the Bifidobacterium adolescentis phylogenetic group by means of a polyphasic approach.

    Abstract:

    In the current work, we describe genome diversity and core genome sequences among representatives of three bifidobacterial species, i.e., Bifidobacterium adolescentis, Bifidobacterium catenulatum, and Bifidobacterium pseudocatenulatum, by employing a polyphasic approach involving analysis of 16S rRNA gene and 16S-23S internal transcribed spacer (ITS) sequences, pulsed-field gel electrophoresis (PFGE), and comparative genomic hybridization (CGH) assays.

  • Exploring the Diversity of the Bifidobacterial Population in the Human Intestinal Tract

    Abstract:

    Although the health-promoting roles of bifidobacteria are widely accepted, the diversity of bifidobacteria among the human intestinal microbiota is still poorly understood. We performed a census of bifidobacterial populations from human intestinal mucosal and fecal samples by plating them on selective medium, coupled with molecular analysis of selected rRNA gene sequences (16S rRNA gene and internally transcribed spacer [ITS] 16S-23S spacer sequences) of isolated colonies. A total of 900 isolates were collected, of which 704 were shown to belong to bifidobacteria. Analyses showed that the culturable bifidobacterial population from intestinal and fecal samples include six main phylogenetic taxa, i.e., Bifidobacterium longum, Bifidobacterium pseudocatenulatum, Bifidobacterium adolescentis, Bifidobacterium pseudolongum, Bifidobacterium breve, and Bifidobacterium bifidum, and two species mostly detected in fecal samples, i.e., Bifidobacterium dentium and Bifidobacterium animalis subp. lactis. Analysis of bifidobacterial distribution based on age of the subject revealed that certain identified bifidobacterial species were exclusively present in the adult human gut microbiota whereas others were found to be widely distributed. We encountered significant intersubject variability and composition differences between fecal and mucosa-adherent bifidobacterial communities. In contrast, a modest diversification of bifidobacterial populations was noticed between different intestinal regions within the same individual (intrasubject variability). Notably, a small number of bifidobacterial isolates were shown to display a wide ecological distribution, thus suggesting that they possess a broad colonization capacity.

    Abstract:

    Five Bifidobacterium strains, VB23T, VB24T, VB25T, VB26T and VB31T, were isolated from chimpanzee (Pan troglodytes), cotton-top tamarin (Saguinus oedipus), Goeldi's marmoset (Callimico goeldii), moustached tamarin (Saguinus mystax) and patas monkey (Erythrocebus patas), respectively, which were kept in two Czech zoos. These strains were isolated from faecal samples and were Gram-positive, non-motile, non-sporulating, anaerobic and fructose-6-phosphate phosphoketolase-positive. Phylogenetic analyses based on 16S rRNA revealed close relatedness between VB23T and Bifidobacterium angulatum LMG 11039T (96.0 %), VB24T and Bifidobacterium pullorum subsp. pullorum DSM 20433T (96.1 %), VB25T and Bifidobacterium goeldii LMG 30939T (96.5 %), VB26T and Bifidobacterium imperatoris LMG 30297T (98.1 %), and VB31T and B. angulatum LMG 11039T (99.40 %). Internal transcribed spacer profiling revealed that VB23T, VB24T, VB25T, VB26T and VB31T had highest similarity to Bifidobacterium breve LMG 13208T (77.2 %), Bifidobacterium longum subsp. infantis ATCC 15697T (85.8 %), Bifidobacterium biavatii DSM 23969T (76.9 %), B. breve LMG 13208T (81.2 %) and B. angulatum LMG 11039T (88.2 %), respectively. Average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) analyses with their closest neighbours supported the independent phylogenetic positions of the strains with values between 86.3 and 94.3 % for ANI and 25.8 and 54.9 % for dDDH. These genomic and phylogenetic analyses suggested that the evaluated strains were novel Bifidobacterium species named Bifidobacterium erythrocebi sp. nov. (VB31T=DSM 109960T=CCUG 73843T), Bifidobacterium moraviense sp. nov. (VB25T=DSM 109958T=CCUG 73842T), Bifidobacterium oedipodis sp. nov. (VB24T=DSM 109957T=CCUG 73932T), Bifidobacterium olomucense sp. nov. (VB26T=DSM 109959T=CCUG 73845T) and Bifidobacterium panos sp. nov. (VB23T=DSM 109963T=CCUG 73840T).
