Ocular lesions in a domestic feline: A closer look at the fungal pathogen sporothrix brasiliensis

Abstract

Sporotrichosis is a dermatozoonosis, caused by dimorphic pathogenic fungi of the genus Sporothrix. Although Sporothrix brasiliensis is the most frequent and pathogenic species identified from the Brazilian sporotrichosis hyperendemic, to the best of our knowledge this is the first report of its molecular diagnosis from a cat with ocular lesions. A 3-month old female, domestic feline presented an ocular manifestation with granuloma in the lower-left palpebral conjunctiva, in addition to mucocutaneous lesions in varied locations throughout the body. Samples were collected for subsequent cytopathology, fungal culture, serology, and molecular genotyping. Itraconazole was prescribed for the treatment of sporotrichosis and the animal was considered clinically cured at the end of 5 months of treatment and discharged. S. brasiliensis cat interactions can manifest with a multitude of clinical forms that resemble either infectious or noninfectious diseases. Both the need for meticulous cat physical evaluation by a veterinarian followed by accurate laboratory diagnosis are key Public Health measures in the Brazilian sporotrichosis hyperendemic area.
