Species/Subspecies: Mycoplasmopsis synoviae
Etymology: Genus name: fungus shaped.
Species epithet: of joint fluid.
Significance:Worldwide distribution.
  [Important]   
Alternative Species Name(s):Mycoplasma synoviae
Taxonomy:
Phylum
Tenericutes
Class
Mollicutes
Order
Mycoplasmatales
Family
Metamycoplasmataceae 
Genus
Mycoplasmopsis
Type Strain: WVU 1853 = ATCC 25204 = NCTC 10124.
Macromorphology (smell): Forms small colonies where some are very typical umbonated ("fried egg appearance") and some lack the "yolk". The macro morphology can be observed in a microscope.
Micromorphology: Very small and pleomorphic. Nonmotile.
Gram +/Gram -:G-, but is normally not gram stained because the cells will then be fragmented.
Catalase/Oxidase:
Fermentation of carbohydrates: Glucose +
Spec. Char.: Lacks a cell wall. Optimal growth temperature: 37°C.
Disease:Infectious synovitis.
Hosts: Chickens and turkeys

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. synoviae is related to M. cynos och M. felis. See the phylogenetic tree (Fig. 214:1) 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.
