The Erysipelotrichia are a class of bacteria of the phylum Bacillota. Species of this class are known to be common in the gut microbiome, as they have been isolated from swine manure [1] and increase in composition of the mouse gut microbiome for mice switched to diets high in fat. [2]

This class has the unusual phylogenetic position (according to phylogenomic and 16S rRNA studies) of branching within Mycoplasmatota, a phylum largely without peptidoglycan cell wall. Its ability to make a peptidoglycan and sporulate, combined with this position as well as Mycoplasmotota metagenomes with similar gene contents, imply that the Mycoplasmatotal lineages have independently reduced their cell walls.
