The most frequent species of dermatophytes of dogs and cats affected by mycoses are Microsporum gypseum and mainly Microsporum canis. The crucial role during the infection process is the production of extracellular enzymes essential for the invasion and establishment of the pathogen in the host tissue. The use of organic plant extracts to control parasites is commonly considered an important alternative. Caapeba Piper marginatum, as well as other species of the same Piperaceae family, has been studied in the control of phytopathogens in agriculture, as well as in the control of the malaria parasite, antifungal and antimicrobial activity. This study aimed to review the literature on dermatophytosis and determine the antifungal potential of Piper marginatum Jacq. against Microsporum gypseum Keywords: Dermatophytosis; anti-fungii; extract; alternative control.Acesso Abertodermatofitoseantifúngicoextratocontrole alternativoCNPQ::CIENCIAS AGRARIAS::MEDICINA VETERINARIA::PATOLOGIA ANIMALTrabalho de Conclusão de Curso
