The taxonomy of the mollicutes (mycoplasmas) has finally been revised thanks to a Canadian and an Israeli research group. This revised taxonomy is based on data from whole genome sequencing of 140 mollicutes. Only members of the so-called mycoides group are still included in the order Mycoplasmatales. Other former members of this order have now been transferred to the order Mycoplasmoidales. This new order Mycoplasmoidales has been divided into the two families Mycoplasmoidaceae and Metamycoplasmataceae, which have been further subdivided into five different genera (see figure). The important purpose of the revision of the taxonomy of the mollicutes was to get a taxonomy that reflects the actual phylogeny of these bacteria.
