Validation of the usefulness of 26S rDNA D1/D2, internal transcribed spacer, and intergenic spacer 1 for molecular epidemiological analysis of <i>Macrorhabdus ornithogaster</i>

Journal of Veterinary Medical Science, 2022
Macrorhabdus ornithogaster (MO) is an infectious fungus that causes gastric damage in birds. In this study, we established nested and seminested polymerase chain reaction (PCR) methods that specifically amplify the domain D1/D2 region (D1/D2) of 26S ribosomal DNA (rDNA), internal transcribed spacer (ITS) of rDNA, and intergenic spacer (IGS) 1 region ...

Development of a validated quantitative polymerase chain reaction assay and fungal culture for the diagnosis of Macrorhabdus ornithogaster in budgerigars (Melopsittacus undulatus)

American Journal of Veterinary Research
Abstract Objective To develop and validate a quantitative PCR (qPCR) assay for detecting Macrorhabdus ornithogaster (MO) and reproducibly culture MO from infected budgerigars (Melopsittacus undulatus). Methods A TaqMan qPCR assay targeting a 94-bp segment of MO 18S rRNA was evaluated for limit of detection, dynamic range, intra-assay variability ...

Changes in gut bacterial communities in canaries infected by Macrorhabdus ornithogaster [PDF]

Avian Pathology, 2018
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.
