Aspectos gerais da fasciolosee de endoparasitoses em capivaras(Hydrochaeris hydrochaeris Linnaeus, 1766)de três parques no Paraná, Brasil / General aspects of Fascioliasis and Endoparasitic diseases in capybaras (Hydrochaeris hydrochaeris Linnaeus, 1766) from three parks in the State of Paraná, Brazil

RESUMO

Este trabalho foi desenvolvido em três parques nos municípios de Curitiba e de São Mateus do Sul, Estado do Paraná, com o objetivo de conhecer a prevalência de parasitos de capivaras (Hydrochaeris hydrochaeris) e a presença de moluscos hospedeiros intermediários de Fasciola hepatica. Foram analisadas, no segundo semestre de 2005, 33 amostras de fezes e processadas pelas técnicas Willis-Mollay, Dennis-Stones & Swanson e Girão & Ueno. A prevalência de parasitos foi 54,5% (18/33) de ovos de Fasciola hepatica; 57,6% (19/33) de oocistos de Eimeria spp.; 36,4% (12/33) de ovos de Cestoda; 30,3% (10/33) de Trychostrongilidae; 15% (5/33) de Capillaria spp. e 12% (4/33) de Ascaridae. Os ovos de Fasciola hepatica mediram, em média, 138,567 μm por 72,960 μm. Somente no Parque Barigüí foram encontrados ovos de Fasciola hepatica e moluscos 46% (51/110) de Physa cubensis, 36% (39/110) de Physa marmorata e 18% (20/110) de Biomphalaria tenagophila. Merece destaque a presença de Fasciola hepatica, agente zoonótico da fasciolose, já registrada em humanos no Estado do Paraná

ABSTRACT

The present study was conducted in three parks of Curitiba and São Mateus do Sul, state of Paraná, Brazil, in order to determine the prevalence of parasites in capybaras (Hydrochaeris hydrochaeris) and the presence of snails as intermediate hosts of Fasciola hepatica. A total of 33 fecal samples were analyzed and processed in the second half of 2005, according to Willis-Mollay, Dennis-Stones & Swanson and Girão & Ueno techniques. The following prevalence rates were observed 54.5% (18/33) for Fasciola hepatica eggs; 57.6% (19/33) for Eimeria spp. oocysts; 36.4% (12/33) for cestode eggs; 30.3% (10/33) for Trychostrongilidae; 15% (5/33) for Capillaria spp. and 12% (4/33) for Ascaridae. Fasciola hepatica eggs measured on average 138.567 μm x 72.960 μm and were found only in Barigüí park, as were the snails 46% (51/110) of which belonged to Physa cubensis, 36% (39/110) to Physa marmorata and 18% (20/110) to Biomphalaria tenagophila. Notably, Fasciola hepatica has been isolated from humans in the state of Paraná
