Description of Candidatus Blautia avicola sp. nov.

Candidatus Blautia avicola (a.vi’co.la. L. fem. n. avis bird; L. suff. -cola inhabitant of; N.L. n. avicola inhabitant of birds)

A bacterial species identified by metagenomic analyses. This species includes all bacteria with genomes that show ≥95% average nucleotide identity (ANI) to the type genome, which has been assigned the MAG ID ChiBcec6-4105 and which is available via NCBI BioSample SAMN15816794. The GC content of the type genome is 46.40% and the genome length is 3.1 Mbp.

Description of Candidatus Blautia avistercoris sp. nov.

Candidatus Blautia avistercoris (a.vi.ster’co.ris. L. fem. n. avis bird; L. neut. n. stercus dung; N.L. gen. n. avistercoris of bird faeces)

A bacterial species identified by metagenomic analyses. This species includes all bacteria with genomes that show ≥95% average nucleotide identity (ANI) to the type genome, which has been assigned the MAG ID 5548 and which is available via NCBI BioSample SAMN15816924. This is a new name for the alphanumeric GTDB species sp002159835. Although GTDB has assigned this species to the genus it calls Blautia_A, this genus designation cannot be incorporated into a well-formed binomial, so in naming this species, we have used the current validly published name for the genus. The GC content of the type genome is 45.38% and the genome length is 2.5 Mbp.

Description of Candidatus Blautia excrementigallinarum sp. nov.

Candidatus Blautia excrementigallinarum (ex.cre.men.ti.gal.li.na’rum. L. neut. n. excrementum excrement; L. fem. n. gallina hen; N.L. gen. n. excrementigallinarum of hen excrement)

A bacterial species identified by metagenomic analyses. This species includes all bacteria with genomes that show ≥95% average nucleotide identity (ANI) to the type genome, which has been assigned the MAG ID ChiSjej6B24-370 and which is available via NCBI BioSample SAMN15816894. Although GTDB has assigned this species to the genus it calls Blautia_A, this genus designation cannot be incorporated into a well-formed binomial, so in naming this species, we have used the current validly published name for the genus. The GC content of the type genome is 49.44% and the genome length is 2.3 Mbp.

Description of Candidatus Blautia excrementipullorum sp. nov.

Candidatus Blautia excrementipullorum (ex.cre.men.ti.pul.lo’rum. L. neut. n. excrementum excrement; L. masc. n. pullus a young chicken; N.L. gen. n. excrementipullorum of young chicken excrement)

A bacterial species identified by metagenomic analyses. This species includes all bacteria with genomes that show ≥95% average nucleotide identity (ANI) to the type genome, which has been assigned the MAG ID CHK197-7439 and which is available via NCBI BioSample SAMN15816885. Although GTDB has assigned this species to the genus it calls Blautia_A, this genus designation cannot be incorporated into a well-formed binomial, so in naming this species, we have used the current validly published name for the genus. The GC content of the type genome is 46.79% and the genome length is 3.3 Mbp.
