Dermatophytosis are skin diseases characterized by being a superficial
infection caused mainly by fungi of the genera Trichophyton, Epidermophyton,
Microsporum and Nannizzia. These diseases can affect canines and felines, also
having a zoonotic potential. Due to the different pharmaceutical presentations of
antifungal compounds present on the market and their easy access, indiscriminate
use occurs, promoting resistance to the main drugs used. Due to unresponsive
therapy and high rates of refractory cases, the costs and duration of treatments
increase. In the search for effective treatments, the discovery of new natural products
is essential, for this it is possible to study microorganisms, since these are a source
of secondary metabolites that may allow the finding of these natural products with
antifungal action capable of overcoming resistance mechanisms, resulting in an
alternative and less aggressive form of treatment.
