The transfer has not been free of scientific disagreement.

The cited TEDDY record reports source-labeled Eubacterium rectale among short-chain-fatty-acid-producing taxa depleted in children who progressed to type 1 diabetes in a prospective cohort of 783 children. A cross-sectional CKD multi-omics study likewise reported source-labeled E. rectale depletion across its 88-participant severity cohort. A 96-participant
Reviews cited by WikiBiome report historical E. rectale labels in cardiovascular and neurodegenerative literature. Their summaries do not establish a disease-wide effect. Likewise, Mendelian-randomization records using the “Eubacterium rectale group” label concern a legacy genus-level feature rather than a verified A. rectalis species measurement.

The transfer has not been free of scientific disagreement. Sheridan and colleagues objected that the evidence did not adequately support moving the narrowed human-gut species definition into the proposed genus.[4]Sheridan 2016 — Objections to the proposed reclassification of Eubacterium rectale as Agathobacter rectalisPaul O.

WikiBiome follows the current NCBI and LPSN selection for canonical naming while retaining that published limitation. Canonicalization therefore records the selected nomenclatural convention; it does not claim unanimous phylogenetic agreement.
Historical publications commonly use “Eubacterium rectale,” and several microbiome GWAS report an “Eubacterium rectale group.” WikiBiome preserves those labels when summarizing what a source measured. A group-level 16S or GWAS label must not be read automatically as a species-resolved observation of A. rectalis.
Reported Human-Microbiome Evidence#
The cited TEDDY record reports source-labeled Eubacterium rectale among short-chain-fatty-acid-producing taxa depleted in children who progressed to type 1 diabetes in a prospective cohort of 783 children.[5]Vatanen et al. 2018 — The Human Gut Microbiome in Early-Onset Type 1 Diabetes from the TEDDY StudyTommi Vatanen, Eric A.

A 96-participant shotgun-metagenomics study of pancreatic ductal adenocarcinoma, autoimmune pancreatitis, and healthy controls reported E. rectale as a discriminating source-era species label and measured lower fecal butyrate in the cancer group.[7]The fecal microbiota of patients with pancreatic ductal adenocarcinoma and autoimmune pancreatitis characterized by metagenomic sequencingWenli Zhou, De Zhang, Zhengpeng Li et al. · 2021Open reference 7 ↓ These studies support cohort-specific associations, not causation or a clinical intervention.

The current cited record set does not substantiate a species-specific metal requirement, toxic-metal susceptibility mechanism, universal abundance range, or therapeutic conclusion. Those claims are therefore not carried into the reconciled page.
