|| Macrorhabdus ornithogaster|
||Genus name: long rod.
Species epithet: from the stomach of bird.
||Avian gastric yeast.|
| ||"Incertae sedis" means that the taxonomic affiliation has not been established.|
||The cells are big (3.0 x 20-50 µm).
|Hosts/substrate||Disease/effect||Clinical picture or result|
|Birds and particularly budgerigars, cockatiels, and finches, but may also appear on poultry including ostriches. ||Megabacteriosis, but a more suitable name of this disease would be megamycosis.||Infections in the digestiv system of birds, which caue the to lose weight and die from malnourishment.|
||Identification can be done by microscopy of the bird's feces, but the fungus does not pass all the way through the digestive system of all affected birds.|
||There is no whole genome sequence reported.

||The taxonomy of this organism is uncertain and it has not yet been placed within any particular family.
|Comment:||Trivialnamn: avian gastric yeast. It was long believed that this organism was a giant bacterium ("megabacterium") because it is gram-positive and Bacillus-like. However, rRNA sequencing and other techniques has shown that this organism is a yeast-type fungus.|
