TLDR A young cat had a rare fungal infection caused by Microsporum gypseum.
A 1- to 2-month-old female cross-breed cat with alopecia, erythema, and crusts on its tail was diagnosed with dermatophytosis caused by Microsporum gypseum, a rare isolate in cats. Microscopic examination revealed epithelial debris, exudate, mycelium, and arthrospores. The M. gypseum isolate was cultured and analyzed using random amplification of polymorphic DNA (RAPD), chitin synthase 1 gene (CHS1) sequencing, and mating experiments. The RAPD band patterns and CHS1 gene sequences of the clinical isolate matched those of Arthroderma gypseum tester strains with 100% similarity. Mating experiments confirmed the isolate as A. gypseum (–) mating type, consistent with molecular analysis results.
