Megasphaera is a genus of Firmicutes bacteria classified within the class Negativicutes.^[1] ^[2]

This classification has been reexamined.^[3] It appears that this genus is a member of the Clostridia.

Phylogeny[]

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) ^[4] and National Center for Biotechnology Information (NCBI)^[5] and the phylogeny is based on 16S rRNA-based LTP release 111 by The All-Species Living Tree Project^[6]
