First cases of cat sporotrichosis found in Campo Grande Brazil

Abstract

Sporotrichosis is a traumatic mycosis affecting the skin or subcutaneous tissues caused by Sporothrix dimorphic fungus. The fungal complex includes several pathogenic species, out of which S. brasiliensis and S. schenckii are predominant in Brazil. In Mato Grosso do Sul (MS) state, the first human and animal cases were reported in 2016 in Corumbá and Ladário cities. Accordingly, we present the first occurrences of feline sporotrichosis detected in the state capital Campo Grande, MS, by the Zoonoses Control Service (ZCS) of the Municipal Public Health Department. The study included four allochthonous cases of feline sporotrichosis originating from Corumbá, MS, attended by the ZCS. All four cats presented classical clinical signs of sporotrichosis, as ulcerative nodular cutaneous lesions. Three slides tested positive by direct microscopy and PCR, followed by Sanger sequencing confirmed Sporothrix brasiliensis in two samples. The initial suspicion and diagnosis of feline sporotrichosis at the ZCS highlights the importance of accurate surveillance of sporotrichosis in non-endemic areas to enhance the capacity to prevent, detect and respond to emerging diseases in Campo Grande.
