Macrorhabdus ornithogaster (Megabacterium) Infection in Adult Hobby Chickens in North America

Avian Diseases, 2011
A field investigation was conducted on a flock of adult hobby chickens showing intermittent signs of enteritis. Roosters examined in the initial field visit and postmortem had cecal worms, roundworms, tetratrichomonads, and coccidiosis. Macrorhabdus ornithogaster was diagnosed histologically in the mucosal isthmus of the proventriculus and ventriculus.

Haematological findings in budgerigars with megabacterium and Trichomonas infections associated with 'going light'

Veterinary Record, 1988
Eighteen budgerigars with clinical signs of 'going light' were euthanased and examined post mortem; ingluvitis caused by Trichomonas gallinae infection was present in seven birds, proventriculitis associated with the presence of megabacteria in eight birds and in three birds both conditions were present.

Phylogenetic analysis identifies the ‘megabacterium’ of birds as a novel anamorphic ascomycetous yeast, Macrorhabdus ornithogaster gen. nov., sp. nov. [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2003
An organism commonly referred to as 'megabacterium' colonizes the gastric isthmus of many species of birds. It is weakly gram-positive and periodic acid-Schiff-positive and stains with silver stains. Previous studies have shown that it has a nucleus and a cell wall similar to those seen in fungi.
