First detection of Macrorhabdus ornithogaster in wild Eurasian Siskins (Carduelis spinus) in Germany

Tierarztliche Praxis Ausgabe K: Kleintiere - Heimtiere, 2015
SummaryThe 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)

An Acute Mortality Event Associated with Novel Macrorhabdus ornithogaster Infection and Underlying Factors in a Newly-Established Captive Group of American White Ibis (Eudocimus albus) Nestlings

Journal of Wildlife Diseases, 2023
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.

Macrorhabdus ornithogaster-associated Avian Macrorhabdosis: A Narrative Review

IgMin Research
Avian 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 ...

Investigation Into the Diagnosis, Treatment and Risk Factors of Macrorhabdus ornithogaster in Australian Cage Birds [PDF]

, 2023
Macrorhabdus ornithogaster is a yeast that grows at the isthmus between the proventriculus and ventriculus in birds. It commonly infects budgerigars (Melopsittacus undulatus) in Australia. Infected budgerigars may show no signs while others die with melaena, malabsorption and emaciation despite what appears to be a ravenous appetite.

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.

The Incidence and Treatment Outcomes ofMacrorhabdus ornithogasterInfection in Budgerigars (Melopsittacus undulatus) in a Veterinary Clinic

Journal of Avian Medicine and Surgery, 2017
Macrorhabdus ornithogaster, avian gastric yeast, is a common cause of gastrointestinal disease in budgerigars ( Melopsittacus undulatus). To better understand the clinical disease in budgerigars presented in a practice population, we reviewed the occurrence, clinical signs, and treatment success of M ornithogaster disease in budgerigars during a 2.5 ...

Comparison of Two Methods for Determining Prevalence of Macrorhabdus ornithogaster in a Flock of Captive Budgerigars (Melopsittacus undulatus)

Journal of Avian Medicine and Surgery, 2017
Macrorhabdus ornithogaster is a yeast organism that infects multiple species of captive and wild birds. Diagnosis of infection in vivo has proven difficult historically, as shedding can be intermittent, and not all positive animals are clinically ill. We compared polymerase chain reaction (PCR) of cloacal swab samples and fecal Gram's stain (FGS) for ...

STUDY OF THE FECAL MICROBIOTA OF CANARIES AFFECTED OR NOT BY MACRORHABDUS ORNITHOGASTER INFECTION USING CULTURE INDEPENDENT APPROACHES [PDF]

, 2017
Macrorhabdus ornithogaster is an ascomycetes yeast, difficult to isolate and store in laboratory, that colonize the gut of several avian species causing digestive disorders. The present study aimed to characterize the microbiota diversity of 45 fecal samples of M.

Diagnosis and Management of Macrorhabdus ornithogaster (Formerly Megabacteria)

Veterinary Clinics of North America: Exotic Animal Practice, 2005
Key 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 ...
