"''Mycoplasma mycoides'' subsp. ''mycoides'' (Mmm)", previously named "''Mycoplasma mycoides'' subsp. ''mycoides'' Small Colony (SC) type (MmmSC)", is known as the agent of
contagious bovine pleuropneumonia (CBPP), a contagious lung disease of cattle. It was first isolated in 1898 by
Edmond Nocard et al. and the first mycoplasma to be isolated at all.
Formerly, ''M. mycoides'' subsp. ''mycoides'' was known as ''Asterococcus mycoides''.
The ''Mycoplasma mycoides'' cluster
''Mycoplasma mycoides'' belongs to the ''Mycoplasma mycoides'' cluster, or
''Mycoplasma mycoides'' group, a group of closely related infectious mycoplasmas, first named by Weisburg et al.
The cluster

*''M. mycoides'' subsp. ''mycoides'' biotype Small Colony (MmmSC)
*''M. mycoides'' subsp. ''mycoides'' biotype Large Colony (MmmLC)

The last one is disputed with respect to the question of being a separate species.
In 2009, L. Manso-Silván et al. proposed to consider ''M. mycoides'' subsp. ''mycoides'' biotype Large Colony as equal with ''M. mycoides'' subsp. ''capri''. Furthermore, they proposed the name ''Mycoplasma leachii'' sp. nov. for ''Mycoplasma'' sp. 'bovine group 7' as a separate species.
Minimal genome project
In 2010, as part of the
Minimal Genome Project, a team of the
J. Craig Venter Institute synthesized a modified version (JCVI-syn1.0) of the 1,000,000 base pair ''M. mycoides'' genome and implanted it into a DNA-free bacterial shell of ''

''; the resulting organism was shown to be self-replicating.
In 2016, the Venter Institute used genes from the JCVI-syn1.0 to synthesize an even smaller genome they call JCVI-syn3.0, that contains 531,560 base pairs and 473 genes.
