| 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. meleagridis is closely related to M. agalactiae and M. bovis. See the phylogenetic tree (Fig. 215:1) where M can mean Mycoplasma, Mesomycoplasma, Metamycoplasma, Mycoplasmoides or Mycoplasmopsis. | ||||||||||||
| Legislation: | Avian mycoplasmosis caused by M. meleagridis is notifyable to the Swedish Board of Agriculture in Sweden | ||||||||||||
| Comment: | Based on whole genome sequencing, the taxonomy of mycoplasmas has recently undergone a comprehensive revision. The new taxonomy has now been 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. | ||||||||||||
