|| Mycoplasma hyopneumoniae|
||Genus name: fungus shaped.

|Forms small and atypical colonies, which lack a clearly defined nipple (no "fried egg appearance") and should be observed in a microscope.
||Non-motile, very small small and pleomorphic
|Gram +/Gram -:||G-, but is normally not gram stained because the cells will then be fragmented.
