Doenças micóticas em gatos no Rio Grande do Sul

Abstract

Fungal disease is included in the differential diagnosis of a wide range of disorders incats. At the Department of Veterinary Pathology of Federal University Federal of Rio Grandedo Sul (SPV-UFRGS), evaluation of records data of cats from January 2005 to December2015 were examined. A total of 1,274 necropsy have been reviewed from which 17 casesof fungal infection was revealed accounting for 1.33%, and a total of 2,615 biopsies havebeen reviewed from which 59 cases of fungal infection was revealed, accounting for 2.25%.We retrospectively analyzed the gross and microscopic findings and the yield of additionaldiagnostic approaches employed. Sporotrichosis was the most common diagnosis with 34cases found in biopsy and five necropsies. Cryptococcosis obtained six diagnoses throughnecropsy and 13 through biopsy. Dermatophytic pseudomycetoma was found in five casesin biopsy and two necropsies. Histoplasmosis diagnosis was obtained in one necropsy andtwo biopsies. Aspergillosis had two cases diagnosed in necropsy. Candidiase and phaeo-hyphomycosisaccounted for one case each. In four occasions, it was not possible to identifythe agent involved and the diagnosis was made regarding the morphological changes: fungaldermatitis, fungal enteritis, mycotic rhinitis, and fungal dermatitis and osteomyelitis.In this study, sporotrichosis could be identified as the most frequent diagnosis of fungaldisease in cats, followed by cryptococcosis and dermatophytic pseudomycetoma.
