ABSTRACT
The reclassification of Butyrivibrio crossotus Moore et al. 1976 (Approved Lists 1980) as Eshraghiella crossota gen. nov., comb. nov. is proposed within the family Lachnospiraceae. This reclassification is based on differences revealed through the analysis of 16S rRNA, groEL, recA, and rpoB genes, as well as genome sequences, distinguishing it from other Butyrivibrio species. Comparative analysis showed that B. crossotus exhibited digital DNA-DNA hybridization (dDDH) values of 19.40-27.20% and average nucleotide identities based on blast (ANIb) values of 67.06-67.64% with other Butyrivibrio species. These values are significantly below the species delineation thresholds (dDDH, 70%; ANIb, 95-96%), justifying the proposed reclassification. Additionally, the results of the average amino acid identity (AAI) analysis indicated that this species shares 59.22-60.17% AAI with the other species of the genus Butyrivibrio, which is below the AAI threshold (65%) for a genus boundary. In addition, biochemical and morphological characteristics also support the proposal that this species is different from other species of the genus Butyrivibrio. The type strain is ATCC 29175T (DSM 2876T=T9-40AT).
