Ocorrência de endoparasitas com potencial zoonótico de transmiss o em fezes de gatos (Felis catus domesticus Linnaeus, 1758) domiciliados na área urbana e regi o metropolitana de Castro – Paraná - Brasil / The occurrence of endoparasites with zoonotic potential of transmission in feces of cats (Felis catus domesticus Linnaeus, 1758) domiciled in the urban and metropolitan areas of Castro - Paraná-Brazil

ResumoAs doen as parasitárias de natureza gastrintestinal destacam-se entre as mais frequentes e importantes afec es envolvendo gatos neonatos, jovens e adultos. Com o objetivo de verificar a ocorrência de endoparasitos, trinta e oito amostras de fezes colhidas de gatos domiciliados na área urbana e regi o metropolitana da cidade de Castro (PR) foram analisadas, mediante a técnica de Willis. Dezenove amostras (50,0%) apresentaram resultado positivo para a presen a de ovos e cistos de endoparasitas; houve predomínio de cistos de Cystoisospora spp. em dez (52,63%). Registrou-se a presen a de ovos de Ancylostoma spp. em duas amostras (10,53%), Toxocara spp. em duas (10,53%) e cápsulas ovígeras e proglotes de Dipylidium caninum em uma (5,26%). Foi observada associa o entre dois gêneros de parasitas em três amostras: a primeira contaminada com ovos de Toxocara spp. e Ancylostoma spp. (10,53%), a segunda com cistos de Giardia sp. e Cystoisospora spp. (5,26%), enquanto ovos de Toxocara spp. e proglotes e cápsulas ovigeras de Dipylidium caninum tiveram seu achado reportado na terceira amostra (5,26%). A identifica o de diferentes gêneros de endoparasitas comprova o risco potencial de contamina o para outros animais e pessoas e ressalta a importancia de um maior controle parasitológico em gatos.AbstractParasitic diseases of gastrointestinal kind stand out as the most frequent and important diseases involving newborn, young and adult cats. In order to verify the occurrence of endoparasites, thirty eight feces samples, which were collected from cats residing in the urban and metropolitan areas of the city of Castro-Paraná, were analyzed through the Willis technique. Nineteen samples (50.0%) tested positive for the presence of eggs and cysts of endoparasites; Cystoisospora spp. Cysts predominated in ten of them (52.63%). There were eggs of Ancylostoma spp. in two samples (10.53%), Toxocara sp. in two (10.53%), and egg capsules and proglottids of Dipylidium caninum in one of the samples (5.26%). It was also observed the association between two kinds of parasites in two samples. One of them was contaminated with eggs of Toxocara spp./Ancylostoma spp.(10.53%), and the other one with cysts of Giardia sp./Cystoisospora spp. (5.26%). Eggs, proglottids and egg capsules of Toxocara spp./Dipilidium caninum were found in one sample (5.26%). The identification of different kinds of endoparasites is a proof of the potential risk of contamination to other animals and people, emphasizing the importance of greater parasitological control in cats.
