Evidence of amphotericin B resistance in Macrorhabdus ornithogaster in Australian cage-birds

Medical Mycology, 2018
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.

Molecular identification and phylogenetic analysis of Macrorhabdus ornithogaster based on the 18S rRNA gene in companion birds of Tehran, Iran. [PDF]

Iranian journal of veterinary research, 2023
Macrorhabdus ornithogaster (MO) is an infectious yeast which can cause acute gastric disturbances in birds. It has a worldwide distribution with a broad host-range of bird species.Molecular identification and phylogenetic analysis of MO based on the 18S rRNA gene in companion birds of Iran.A total of 54 stool samples were taken from birds (10 species ...

Prolonged fecal shedding of ‘megabacteria’ (Macrorhabdus ornithogaster) by clinically healthy canaries (Serinus canaria) [PDF]

Medical Mycology, 2013
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 ...

Macrorhabdus ornithogaster Infection and Spontaneous Proventricular Adenocarcinoma in Budgerigars ( Melopsittacus undulatus ) [PDF]

Veterinary Pathology, 2019
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.

Mechanism of GSDMD in the Pathogenesis of Pasteurella multocida PmCQ2 [PDF]

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Pasteurella multocida serotype A (PmCQ2), a Gram‐negative zoonotic pathogen, causes severe respiratory disease in a variety of domestic and wild animals, leading to high morbidity and mortality and substantial agricultural economic losses. Pyroptosis, a gasdermin‐mediated programmed cell death mechanism, facilitates pathogen clearance but exacerbates ...

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

, 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.

Le point sur macrorhabdus ornithogaster, agent étiologique de la mégabactériose aviaire [PDF]

, 2015
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 ...

GUT MICROBIOTA CHANGES ON CANARIES WITH MACRORHABDUS ORNITHOGASTER INFECTION IN AN AVIARY CENTER

, 2017
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]

, 2018
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 ...
