Abstract
Pets have conquered the daily lives of families worldwide and because they have a close relationship with humans, they can transmit mycotic zoonoses such as dermatophytosis, malassezioses and candidosis. Studies show that fungi with pathogenic potential have already been granted in clipping instruments and bath articles in veterinary clinics and in Pet Shops. In the absence of data in the city of Sinop - MT, this study aimed to isolate fungi with pathogenic potential in clipping instruments used in the routine of Pet Shops and to identify etiological agents capable of causing mycotic zoonoses. Samples were carried out in 18 clipping instruments, without cleaning, from 10 Pet Shops (A, B, C, D, E, F, G, H, I, J) in the city of Sinop - MT with swabs and sterile carpets square and then seeded in Sabouraud agar with 0.05% chloramphenicol and mycobiotic agar, incubated at room temperature (25°C) for 30 - 45 days. The dermatophytes and non-dermatophyte filamentous fungi were identified using the microculture technique and urease test and as yeasts using a urease test, zymogram, auxanogram, germ tube and corn meal agar with polysorbate 80. Of the samples from 18 clipping instruments, 15 were positive for at least one fungal genus. The yeast that showed a high prevalence of isolation in clipping instruments from the studied Pet Shops (B, C, D, E, H and J) was Malassezia pachydermatis (86.7%), followed by the genus Candida spp. (C and D; 26.7%), filamentous fungi of the genus Aspergillus spp. (A; 13.3%), Microsporum canis (B; 13.3%) and Trichosporon spp. (J, 6.7%). Our results demonstrate that Pet Shops treat a large number of animals daily in a single environment, which may amplify the risk of spreading zoonoses, as an asymptomatic or sick carrier animal can potentially transmit the microorganism to other animals inside the store and thus to a large number of new pet owners. There is a need to reinforce the commercial requirements specialized in bathing and grooming in the city of Sinop - MT on the good practices of cleaning and disinfection of the elements used and the environment, eliminating or eliminating the risk of contracting mycotic zoonoses.

Summary
Pets have conquered the daily lives of families worldwide and because they have a close relationship with humans, they can transmit mycotic zoonoses such as dermatophytosis, malassezioses and candidosis. In the absence of data in the city of Sinop - MT, this study aimed to isolate fungi with pathogenic potential in clipping instruments used in the routine of Pet Shops and to identify etiological agents capable of causing mycotic zoonoses. The most cases in dogs are caused by Microsporum canis, M. gypseum and Trichophyton mentagrophytes It can be transmitted through direct contact, both symptomatic and asymptomatic host, or by arthroconidia found in the environment. Fomites, such as brushes, blades and clipping instruments, are potential transmitters and this is exacerbated by the fact that fungal structures of dermatophytes are resistant to environmental conditions in which infectious arthroconidia present in the fur and skin can survive for long periods (Moriello et al, 2017). Several non - C.albicans species have been identified in asymptomatic dogs and associated with disease such as Candida parapsilosis and Candida tropicalis (Skeldon et al, 2020)
