Description of Candidatus Ruminococcus avistercoris sp. nov.

Candidatus Ruminococcus 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 CHK186-6582 and which is available via NCBI BioSample SAMN15816883. Although GTDB has assigned this species to the genus it calls Ruminococcus_G, 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 50.07% and the genome length is 2.3 Mbp.

Description of Candidatus Ruminococcus gallistercoris sp. nov.

Candidatus Ruminococcus gallistercoris (gal.li.ster’co.ris. L. masc. n gallus chicken; L. neut. n. stercus dung; N.L. gen. n. gallistercoris of chicken 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 ChiBcec12-341 and which is available via NCBI BioSample SAMN15816918. This is a new name for the alphanumeric GTDB species sp900552925. Although GTDB has assigned this species to the genus it calls Ruminococcus_H, 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 62.03% and the genome length is 2.1 Mbp.

Description of Candidatus Ruminococcus intestinipullorum sp. nov.

Candidatus Ruminococcus intestinipullorum (in.tes.ti.ni.pul.lo’rum. L. neut. n. intestinum gut; L. masc. n. pullus a young chicken; N.L. gen. n. intestinipullorum of the gut of young chickens)

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 1485 and which is available via NCBI BioSample SAMN15816905. Although GTDB has assigned this species to the genus it calls Ruminococcus_B, 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 35.77% and the genome length is 2.1 Mbp.
