Disease/effect:
| 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. |
|
Diagnostics:
| 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. |

Taxonomy/phylogeny:
|
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. |
