Species/Subspecies: Mycoplasma dispar
Etymology: Genus name: fungus shaped.
Species epithet: different.
Significance:  [Of minor importance]   
Taxonomy:
Phylum
Tenericutes
Class
Mollicutes
Order
Mycoplasmatales
Family
Mycoplasmataceae 
Genus
Mycoplasma
Type Strain:
Macromorphology (smell): Forms small and atypical colonies, which are not umbonated (no "fried egg appearance") and should be observed in a microscope.
Micromorphology: The small cells are coccoid or short filamentous.
Gram +/Gram -:G-, but is normally not gram stained because the cells will then be fragmented.
Metabolism: Facultatively anaerobic. M. dispar is a glucose fermenter, which lowers the pH in the growth medium.
Catalase/Oxidase:
Spec. Char.:
