Veterinary bacteriology: information about important bacteria
|Etymology:||Genus name: besides Mycoplasma (fungus shaped).|
Species epithet: from joint fluid of pig.
|Alternative Species Name(s):||Mycoplasma hyosynoviae|
|Type Strain:||S16 = ATCC 25591 = NCTC 10167.|
|Macromorphology (smell):||Forms small and very typical umbonated colonies ("fried egg appearance"), which can be observed in a microscope.|
|Micromorphology:||The cells are coccoid to filamentous.|
|Gram +/Gram -:||G-, but is normally not gram stained because the cells will then be fragmented.|
|Metabolism:||Energy source: glucose (pH is decreased).|
|Other Enzymes:||Urease -|
|Fermentation of carbohydrates:||Glucose +|
|Spec. Char.:||Lacks a cell wall. Optimal growth temperature: 37°C.|
|16S rRNA Seq.:|
||About 25 species have been described within the genus Metamycoplasma.
Note that the letter M in the phylogenetic tree (Fig. 216:1) 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.|
