|Category:||Notifiable diseases and bacteria|
|Etymology:||Genus name: similar to mycoplasma (fungus shaped).|
Species epithet: from a turkey.
|Alternative Species Name(s):||Mycoplama meleagridis|
|Type Strain:||17529 = ATCC 25294 = NCTC 10153.|
|Macromorphology (smell):||Forms small colonies, which are not always umbonated ("fried egg appearance"). The macro morphology can be observed in a microscope.|
|Micromorphology:||Small coccoid cells.|
|Gram +/Gram -:||G-, but is normally not gram stained because the cells will then be fragmented.|
|Metabolism:||Fakulatively anaerobic.Energy source: arginine (pH is increased).|
|Fermentation of carbohydrates:||Glucose -|
|Spec. Char.:||Lacks a cell wall.|
|Disease:||The disease is transmitted mainly through vertical spread of infection from breeding animals and symptoms are seen mainly among turkey poultries.
|16S rRNA Seq.:|
||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.|
|New families introduced within the order Enterobacterales|
The order Enterobacterales (formerly called Enterobacteriales) previously consisted of bacteria with different properties and phylogenetically, these bacteria were far apart. In order for the taxonomy to be more in line with phylogeny, some of these bacteria have, therefore, been sorted into 6 new families.Published 2022-04-13. Read more...
