Changes in gut bacterial communities in canaries infected by Macrorhabdus ornithogaster [PDF]
Macrorhabdus ornithogaster is an opportunistic yeast that colonizes the gastric mucosa of many avian species. Until now, no studies have focused on the influence of a gastric infection on the balance of the intestinal microbiota of birds. In this study, 44 faecal samples from individual canaries, with and without M.

Prolonged fecal shedding of ‘megabacteria’ (Macrorhabdus ornithogaster) by clinically healthy canaries (Serinus canaria) [PDF]
Macrorhabdus ornithogaster, often referred to as 'megabacterium', is an ascomycetous yeast usually found colonizing the mucosal surface of the isthmus existing between the glandular and grinding stomach of a wide diversity of bird species. However, this yeast can also behave as an avian pathogen, therefore representing a potential threat to bird ...

Evidence of amphotericin B resistance in Macrorhabdus ornithogaster in Australian cage-birds
Amphotericin B is widely used for the treatment of Macrorhabdus ornithogaster infections. To date, however, there have been no randomized controlled trials confirming its efficacy where cure was confirmed by postmortem examination. To determine the efficacy of amphotericin B against M. ornithogaster, a three-part study was undertaken.

Macrorhabdus ornithogaster Infection and Spontaneous Proventricular Adenocarcinoma in Budgerigars ( Melopsittacus undulatus ) [PDF]
Proventricular infection with the anamorphic, ascomycetous yeast Macrorhabdus ornithogaster and disease associated with infection (macrorhabdiosis) have been widely reported in budgerigars ( Melopsittacus undulatus). Proventricular adenocarcinoma has also been previously reported in this species.

GUT MICROBIOTA CHANGES ON CANARIES WITH MACRORHABDUS ORNITHOGASTER INFECTION IN AN AVIARY CENTER
Introduction Birds have an extreme morphological diversity, diets that vary widely and a complex ecosystem which contains a huge number of microorganisms, dominated by members of the Firmicutes, with Actinobacteria, Bacteroidetes, and Proteobacteria also commonly observed.

A NEW ELISA METHOD TO EVALUATE THE HUMORAL HOST RESPONSE TO MACRORHABDUS ORNITHOGASTER PROVENTRICULAR INFECTION IN BIRDS [PDF]
In several species of birds, the infection with Macrorhabdus ornithogaster (MO) and the associated proventriculitis has long been known1,2. To date, no study has shown whether MO infection induces a specific immune response in affected birds. Positive aviaries of canaries and budgerigars have been identified and blood collections have been performed ...

Le point sur macrorhabdus ornithogaster, agent étiologique de la mégabactériose aviaire [PDF]
aLa mégabactériose aviaire ou proventriculite fongique est une maladie infectieuse des oiseaux, causée par une levure ascomycète anamorphique, Macrorhabdus ornithogaster, initialement identifiée comme une bactérie géante. Depuis sa découverte au début des années 1980, la levure a suscité et suscite encore de nombreuses interrogations notamment sur sa ...

MACRORHABDOSIS IS OPPORTUNISTIC INFECTION OF BIRDS: DIAGNOSIS AND TREATMENT
The microorganism Macrorhabdus ornithogaster was discovered by Van Herck in 1984 and assigned to bacteria [1, 2], but later electron microscopic and molecular genetic studies of various authors have established its belonging to yeast according to the ...

Infection trials in mice suggest thatMacrorhabdus ornithogasteris not capable of growth in mammals [PDF]
The objective of this study was to determine if Macrorhabdus ornithogaster, a yeast recovered from the junction of the proventriculus and ventriculus of the stomach of parrots and other birds, can infect mice. Fifteen healthy ARC (S) female mice (age 10 weeks) were incoculated with M.
