Abstract

BACKGROUND: This study investigated environmental contamination by Sporothrix spp. in a veterinary facility specialised in treating cats with sporotrichosis. METHODS: Twelve samples were collected from frequently touched surfaces and cages of three cats at different treatment stages. Sampling sites included a procedure table, door handle, faucet, ethanol sprayer, an identification card with visible secretions, and cage components. Samples were cultured on Mycosel agar. Fungal growth was assessed through micromorphological analysis. RESULTS: Sporothrix was isolated from four samples (33%), one from the stainless-steel procedure table and the others associated with the cages of two symptomatic cats. Cat #1, with active ulcerative lesions, had positive cultures from both the cage grid and latch. Cat #2, in early treatment and showing respiratory signs, had fungal growth on the cage grid. No contamination was detected from Cat #3's environment, and for the remaining sports swapped. CONCLUSION: These findings suggest that cage surfaces in veterinary settings can be a source of environmental contamination and potential occupational exposure.
