Paraclostridium is a genus of Gram-positive obligately anaerobic rod-shaped bacteria.

Taxonomy

The genus contains several species originally placed in Clostridium , which the genus name still refers to. Paeniclostridium was separately described as an independent genus in 2016 moving P. ghonii and P. sordellii from Clostridium. Based on additional research of the genomes of Peptostreptococcaceae species, Paeniclostridium was brought into synonymy with Paraclostridium. ^[2]

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) ^[1] and National Center for Biotechnology Information (NCBI) ^[3]
