|16S rRNA Seq.:|
||About 125 species have been described within the genus Mycoplasma. M. leachii belongs to the so-called mycoides group. These mycoplasmas are more closely related to mollicutes within the genus Spiroplasma, which are plant pathogens, than with most other members of the genus . See the phylogenetic tree.|
|Comment:||The mollicutes lack a cell wall and have recently been transferred from the phylum Firmicutes to a new phylum, namely Tenericutes.|
