Taxonomy/phylogeny:
 
Mycoplasmopsis is the largest genus among mollicutes of veterinary importance and about 55 species have been described so far within this genus. M. felis is closely related to M. cynos and M. synoviae. See the phylogenetic tree (Fig. 178:2) where M can mean Mycoplasma, Mesomycoplasma, Metamycoplasma, Mycoplasmoides or Mycoplasmopsis.
Comment:Based on whole genome sequencing, the taxonomy of mycoplasmas has recently undergone a comprehensive revision. The new taxonomy is about to be introduced in VetBact, but it will still be possible to search for the alternative species names. Read more about the revised taxonomy of the mollicutes under the Term list of VetBact and see also reference 164 below.

The revised taxonomy of the mollicutes

The revised taxonomy of mollicutes (mycoplasmas) has now been introduced on VetBact, which means that many of the species have been given new genus names or moved to another higher taxon.
