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 CHK33-6455 and which is available via NCBI BioSample SAMN15816975.

Description of Candidatus Galloscillospiraceae fam. nov.

Candidatus Galloscillospiraceae (Gall.os.cil.lo.spi.ra.ce’ae. N.L. fem. n. Galloscillospira. type genus of the family genus; N.L. suff. –ceae to denote a family; N.L. fem. pl. n. Galloscillospiraceae, the family of the genus Galloscillospira)

A bacterial family identified by metagenomic analyses. This family has been defined by the absence of a family assignment for the type species when GTDB-Tk v1.3.0 is applied to GTDB Release 05-RS95 (Chaumeil et al., 2019; Parks et al., 2020). GTDB assigns the type species and thus the family to the order Oscillospirales.

Description of Candidatus Gemmiger avicola sp. nov.

Candidatus Gemmiger 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 ChiBcec8-13705 and which is available via NCBI BioSample SAMN15816825. This is a new name for the alphanumeric GTDB species sp900548355. The GC content of the type genome is 61.69% and the genome length is 2.3 Mbp.

Description of Candidatus Gemmiger avistercoris sp. nov.

Candidatus Gemmiger 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 CHK188-11489 and which is available via NCBI BioSample SAMN15816604. The GC content of the type genome is 63.30% and the genome length is 2.2 Mbp.

Description of Candidatus Gemmiger avium sp. nov.

Candidatus Gemmiger avium (a’vi.um. L. fem. pl. n. avium 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 ChiGjej4B4-15321 and which is available via NCBI BioSample SAMN15816926. This is a new name for the alphanumeric GTDB species sp002160955. Although GTDB has assigned this species to the genus it calls Gemmiger_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 62.71% and the genome length is 2.6 Mbp.

Description of Candidatus Gemmiger excrementavium sp. nov.

Candidatus Gemmiger excrementavium (ex.cre.ment.a’vi.um. L. neut. n. excrementum excrement; L. fem. n. avis bird; N.L. gen. n. excrementavium of bird excrement)

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 3436 and which is available via NCBI BioSample SAMN15816690. The GC content of the type genome is 60.89% and the genome length is 2.5 Mbp.
