Macrorhabdus ornithogaster (Megabacterium) Infection in Adult Hobby Chickens in North America
Avian Diseases, 2011A 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.

Diagnosis and Management of Macrorhabdus ornithogaster (Formerly Megabacteria)
Veterinary Clinics of North America - Exotic Animal Practice, 2005Key to understanding Macrorhabdus ornithogaster is knowing what it is. When it was first described, it was recognized correctly as being a yeast. It stained with silver stains and the periodic acid-Schiff stain (PAS), both of which stain fungi [1,2]. Because of its unusual long, slender shape, however, subsequent investigators could not demonstrate a ...

Macrorhabdus ornithogaster, a yeast found only at the junction between the ventriculus and proventriculus, can infect a wide range of birds. Infection is often subclinical but can also result in gastrointestinal signs. Direct observation of the organism in the feces is a specific but somewhat insensitive means of diagnosis.

Occurrence of Macrorhabdus ornithogaster in exotic birds
Polish Journal of Veterinary SciencesAvian gastric yeast ( Macrorhabdus ornithogaster) is a microorganism that infects aviary birds worldwide, both captive and wild. A total number of 352 birds, belonging to 18 avian species, were examined from 2019 to 2022 for M. ornithogaster, using fecal smears of live birds or cytological samples of the proventriculus taken at necropsy.

Over a 4-mo period, a Michigan zoo had 32 budgerigars, Melopsittacus undulatus, from their flock die. Whole animals or formalin-fixed tissues were submitted to Michigan State University Veterinary Diagnostic Laboratory for diagnosis. Avian gastric yeast infection, Macrorhabdus ornithogaster, was diagnosed in seven birds.

Macrorhabdus ornithogaster-associated Avian Macrorhabdosis: A Narrative Review
IgMin ResearchAvian macrorhabdosis is a disease of wild and captive birds (psittacines, passerines and other species) distributed worldwide, and is caused by the opportunistic yeast Macrorhabdus ornithogaster. The disease is usually chronic, and is manifested by nonspecific clinical signs (emaciation, anorexia, depression, cachexia and ultimately death), or ...

First detection of Macrorhabdus ornithogaster in wild Eurasian Siskins (Carduelis spinus) in Germany
Tierarztliche Praxis Ausgabe K: Kleintiere - Heimtiere, 2015SummaryThe colonization of the gastric ascomycetous yeast Macrorhabdus (M.) ornithogaster could be associated with a chronic wasting disease in several bird species in captivity. The prevalence and clinical relevance of M. ornithogaster in wild birds is unknown in detail.In the wintering season 2012/13 injured Eurasian Siskins (Carduelis spinus, n = 8)

Spreading of Macrorhabdus Ornithogaster in Ornamental Bird Aviaries in Piedmont
, 2019 Avian gastric yeast (AGY) Macrorhabdus ornithogaster, has a worldwide distribution and currently colonize the proventriculus and ventriculus of a wide of bird species (PHALEN, 2014), representing a potential threat to bird breeders. The aim of this study was to assess the presence of AGY in breeding ornamental birds, rearing in Piedmont.

Twenty-four American white ibis (Eudocimus albus) nestlings were collected in Florida (USA) on 17 April 2017 to establish a captive flock. On 7 May 2017, three birds died suddenly, following severe lethargy, hemorrhaging from the mouth and nares, anorexia, and production of bright-green colored feces.
