Plain-English summary
A 2-year-old female Persian cat was brought to the vet with a painful ear infection in her left ear. After examining a sample from the ear, the vet found yeast cells, which led to the identification of a specific type of yeast called Stephanoascus ciferrii. This was the first time this yeast had been found in a cat. The cat was treated based on the findings, and the specific treatment details were not provided, but identifying the cause was crucial for her recovery.

Abstract
The present study deals with the first isolation of Stephanoascus ciferrii from a cat. A 2-year-old female Persian cat weighing 2.25 kg was referred to an animal hospital with a chief complaint of otitis externa of the left ear. Microscopic examination of specimen from the left ear disclosed yeast cells. The colony of the clinical isolate was cream-colored, rough, raised and wrinkled. The microscopic examination of the clinical isolate revealed abundant branched and septated mycelia with small ramified chains of oval blastoconidia, variable in size, and arranged alongside the hyphae. Amplification of the isolate DNA with LSU rDNA primers yielded a fragment of about 570 bp, whose nucleotide sequence of the isolate showed 100% similarity to that of Stephanoascus ciferrii in the GenBank database. Therefore, the isolate was identified as Stephanoascus ciferrii, confirming the result of mycological examination by molecular analysis.
