| Taxonomy/phylogeny:
|
About 10 species have been described within the genus Ureaplasma. See the phylogenetic tree (Fig. 209:1), but note that M can mean Mycoplasma, Mesomycoplasma, Metamycoplasma, Mycoplasmoides or Mycoplasmopsis in the tree. | ||||||||
| Comment: | Belongs to the normal flora, but may cause opportunistic infections.
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. | ||||||||
