|Etymology:||Genus name: suggests lack of a requirement for cholesterol.|
Species epithet: named after the Brittish virologist Patrick Laidlaw (1881-1940), who first isolated this organism.
|Significance:||Of no direct importance for veterinary medicine
[Of minor importance]
|Type Strain:||PG-8 = ATCC 23206 = NCTC 10116|
||Small colonies (0.2-2 mm), with a shape resembling a fried egg|
|Micromorphology:||Small, pleomorphic and nonmotile organisms (0.2-0.5 µm in diameter).|
|Gram +/Gram -:||G-, but is normally not gram stained since the cells are fragile and fragmented by this staining method.|
|Other Enzymes:||Arginine -, urease -|
|Fermentation of carbohydrates:||Glucose +|
|Spec. Char.:||Lacks a cell wall. Temperature optimum: 37°C, but grows at 20-41°C|
|Hosts:||Has been isolated from manure, soil, plants, insects and many different mammalian species|
|16S rRNA Seq.:|
||About 20 species have been described within the genus Acholeplasma, but all species names have not yet been aproved. This genus is closely related to a group of plant pathogens, which used to be called phytoplasmas. It has not been possible to cultivate these bacteria and this genus should, therefore, be called: "Candidatus Phytoplasma".|
|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 for some mycoplasmas the names have not changed and this applies to members of the genus Acholeplasma.
Sometimes found as a contaminant of cell cultures.
|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.Published 2021-11-25. Read more...
