Abstract

Feline sporotrichosis is a subcutaneous, infectious, and contagious mycosis, with zoonotic characteristics. Until now there are no reports on the isolation of Sporothrix sp. in cats in the state of Pará. The present work aimed to isolate Sporothrix spp. from a cat with possible zoonotic involvement in the city of Belém, Pará. Through the active search for suspected cases of sporotrichosis, carried out by members of the Center for the Control of Zoonoses of Belém (CCZ, Belém) the suspicion of the disease in a feline was reported, with probable transmission to its owner. Clinical evaluation was performed, and biological material was collected from the animal for identifying the agent. Microscopic evaluation of the collected sample and microbial culture confirmed the presence of Sporothrix sp. in the sample. This study is the first to report the microbiological isolation of Sporothrix sp. in a cat in the metropolitan region of Belém, Pará, with possible zoonotic transmission. This indicates a probable underreporting of cases, an unknowing regarding the reality of health conditions and the need for more accurate and comprehensive evaluation of sporotrichosis in this region.

Highlights

Feline sporotrichosis is a subcutaneous, infectious, and contagious mycosis with a zoonotic characteristic
S. brasiliensis is an emerging species that is restricted to Brazil and with high potential for zoonotic transmission (Rodrigues et al, 2016)
S. brasiliensis is associated with cats fection, and its distribution in Brazil is restricted to the Southern and Southeastern states (Rodrigues et al, 2014)

Summary

Introduction

Feline sporotrichosis is a subcutaneous, infectious, and contagious mycosis with a zoonotic characteristic. It is caused by a dimorphic fungus belonging to the Sporothrix schenckii complex, and each species differs with respect to their geographical distribution. S. brasiliensis is associated with cats fection, and its distribution in Brazil is restricted to the Southern and Southeastern states (Rodrigues et al, 2014). There are no reports on the isolation of this fungus from the cats in the state of Pará, cases have been diagnosed in humans, with one died (Falcão et al, 2019). As required notification are occurs only in the state of Rio de Janeiro, and the cases in Pará are probably underreported and there is an unknowing regarding the actual situation of sporotrichosis. In this study aimed to isolate Sporothrix sp. in a cat with possible zoonotic involvement in the city of Belém, Pará
