|Etymology:||Genus name: similar to mycoplasma (fungus shaped).|
Species epithet: of the lung.
|Significance:||[Of minor importance]|
|Alternative Species Name(s):||Mycoplasma pulmonis|
|Type Strain:||PG34 = ATCC 19612 = NCTC 10139.|
|Macromorphology (smell):||Forms small and very typical umbonated colonies ("fried egg appearance"), which can be observed in a microscope.|
|Micromorphology:||Very small and pleomorphic or flask-shaped. This bacterium is motile and can glide on surfaces.|
|Gram +/Gram -:||G-, but is normally not gram stained because the cells will then be fragmented.|
|Metabolism:||Facultatively anaerobic. Energy source: glucose (pH is decreased).|
|Spec. Char.:||Lacks a cell wall.|
|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. See the phylogenetic tree (Fig. 33:1) 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 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 names of taxa within the classification category phylum|
During October 2021, an article was published by A. Oren och G.M. Garrity, in which new names are proposed for a number of taxa within the classification category phylum. This has resulted in many discussions in social media about whether it was really necessary to make these changes, which have created confusion among microbiologists and other professionals who come into contact with bacteriology.Published 2022-09-28.
