Mycoplasmataceae

Mycoplasmataceae is a family of bacteria<ref>E.A. Freundt The classification of the pleuropneumonia group of organisms (Borrelomycetales) Template:Webarchive International Bulletin of Bacteriological Nomenclature and Taxonomy, 1955, 5, 67–78.] (See page 73)</ref> in the order Mycoplasmatales. This family consists of Mycoplasma and four more genera.<ref name=LPSN/>

In 1967, the order Mycoplasmatales was incorporated into the class Mollicutes.<ref>Template:Cite journal</ref> Sexually transmitted species and Ureaplasma are classified in Mycoplasmoidaceae since 2018.<ref name=Gupta18>Template:Cite journal</ref>

Taxonomy

Mycoplasma

{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} Mycoplasma is a genus of bacteria that lack a cell wall and possess a three-layered cellular membrane.<ref name=Sherris>Template:Cite book</ref> They can be parasitic or saprotrophic.

Several species formerly classified as Mycoplasma are sexually transmitted and pathogenic in humans (see Template:Section link). Others are found on cats, dogs, and barnyard fowl.

Taxa infecting insects

A few genera infecting insects were added to this family in 2019 using molecular phylogenetic evidence. These genera were originally called Entomoplasmataceae and believed to be monophyletic.<ref name=Tully>Revised taxonomy of the class Mollicutes: proposed elevation of a monophyletic cluster of arthropod-associated mollicutes to ordinal rank (Entomoplasmatales ord. nov.), with provision for familial rank to separate species with nonhelical morphology (Entomoplasmataceae fam. nov.) from helical species (Spiroplasmataceae), and emended descriptions of the order Mycoplasmatales, family Mycoplasmataceae. Tully J.G., Bove J.M., Laigret F. and Whitcomb R.F., Int. J. Syst. Bacteriol., 1993, volume 43, pages 378-385 (articleTemplate:Dead link)</ref> However, work in 2019 found it to be a paraphyletic group by the exclusion of Mycoplasma. The two original genera (Mesoplasma and Entomoplasma) were also found to be in need of breaking up due to polyphyly. As a result five genera were finally added:<ref name=Gupta19>Template:Cite journal</ref>

• Mesoplasma (formerly "Mesoplasma clade I")
• Entomoplasma (formerly "Entomoplasma clade I")
• Tullyiplasma (formerly "Mesoplasma clade II")
• Williamsoniiplasma (formerly "Entomoplasma clade II")
• Edwardiiplasma (formerly "Mesoplasma clade III")
