}}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. PhylogenyThe 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] {{Clade|1={{clade |1=?M. hominis ♠ |2=M. micronuciformis Marchandin et al. 2003 |3={{clade |1=Anaeroglobus geminatus Carlier et al. 2002 |2={{clade |1=M. elsdenii (Gutierrez et al. 1959) Rogosa 1971 (type sp.) |2={{clade |1=M. cerevisiae Engelmann and Weiss 1986 |2={{clade |1=M. paucivorans Juvonen and Suihko 2006 |2=M. sueciensis Juvonen and Suihko 2006 }} }} }} }} }} }} Notes: ♠ Strains found at the National Center for Biotechnology Information (NCBI) but not listed in the List of Prokaryotic names with Standing in Nomenclature (LPSN) See also
