Morphology of eggs of Dioctophyme renale Goeze, 1782 (Nematoda: Dioctophymatidae) and influences of temperature on development of first-stage larvae in the eggs.
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 degrees C, GII--20 degrees C, and GIII--26 degrees C) was repeated five times. Eggs showed average measures of 67.23 x 42.78 microm, and the mean incubation time was inversely proportional to the incubation temperature. Larvae motility was observed one week after being observed in eggs.
