Abstract: | An 8-year-old, spayed, female Shiba dog was presented to a referring veterinarian with a
complaint of chronic diarrhea and anorexia. Ultrasound and radiographs revealed an
irregular mass in the pelvic cavity. The mass and the affected section of colon were
surgically removed. Histopathological examination revealed multifocal coalescing
granulomas and effaced intestinal structures. Central necrotic debris surrounded by
multinucleated giant cells, lymphocytes, plasma cells and neutrophils was observed.
Numerous, irregularly branched hyphae with pale basophilic, thin walls and occasional
bulbous enlargements at the tips were present. Polymerase chain reaction identified
Basidiobolus ranarum, successfully confirming a definitive diagnosis of
basidiobolomycosis. To the best of our knowledge, this is the first report of intestinal
basidiobolomycosis in a dog. |
