Resumo
Este estudo teve a finalidade de fornecer dados morfológicos de ovos de D. renale e do desenvolvimento de larvas de primeiro estádio em ovos mantidos em diferentes temperaturas. Os ovos foram obtidos por centrífugação da urina de cães parasitados e colocados em placas de Petri em estufa BOD, durante 90 dias. O experimento consistiu de três tratamentos (GI - 15 ºC, GII - 20 ºC e GIII - 26 ºC) com cinco repetições cada. Os ovos apresentaram tamanho médio de 67,23 x 42,78 µm, e o tempo médio de incubação foi inversamente proporcional à temperatura de incubação e as larvas apresentaram motilidade por aproximadamente uma semana após sua formação.
This study aims to provide information on morphological data of D. renale eggs, as well as on first-stage larvae development into eggs kept at different temperatures. Eggs were obtained by centrifugation of infected dog urine, placed in Petri dishes, and stored in BOD chamber for a 90-day period. Each treatment (GI - 15 ºC, GII - 20 ºC, and GIII - 26 ºC) was repeated five times. Eggs showed average measures of 67.23 x 42.78 µm, and the mean incubation time was inversely proportional to the incubation temperature. Larvae motility was observed one week after being observed in eggs.
