Plain-English summary

A 1- to 2-month-old female cross-breed cat was brought in with hair loss, redness, and crusty patches on her tail. Tests revealed that she had a fungal skin infection caused by Microsporum gypseum, which is not commonly found in cats. The vet confirmed the diagnosis through a culture and genetic testing. Treatment typically involves antifungal medications, and with proper care, the cat can recover fully from this skin condition.

Abstract

The 1- to 2-month-old female cross-breed cat presented with alopecia, erythema and many crusts were present on the tail. Microscopic examination of crusts from the tail disclosed epithelial debris, exudate, mycelium, and arthrospores. Microsporum gypseum which is rarely isolated from cats as a causative agent of dermatophytsis was cultured from the crusts on a 1/10 Sabouraud glucose agar at 27 degrees C for 1 week. The isolate of M. gypseum from the cat was examined by random amplification of polymorphic DNA (RAPD), chitin synthase 1 gene (CHS1) sequence and mating experiments. The RAPD band patterns of the clinical isolate of M. gypseum was identical to those of tester strains of Arthroderma gypseum. Nucleotide sequence analysis of the CHS1 gene fragments from the isolate and a tester strain of A. gypseum showed 100% similarity. The mating experiments on the clinical isolate of M. gypseum completely agreed with the results from RAPD and CHS1 gene sequence. The isolate from the cat was confirmed to be A. gypseum (-) mating type, which was consistent with the result of mycological examination by molecular analyses.
