Los huevos de F. hepática se incubaron a 22 °C y 25 °C durante 14 d en oscuridad. Se evaluaron siete subpoblaciones bajo los parámetros de velocidad curvilínea, lineal y media por 10 h después de la eclosión. No se observaron diferencias significativas entre la temperatura de incubación y el porcentaje de huevos eclosionados. El porcentaje de miracidios de la incubación a 22 °C fue diferente estadísticamente a la de 25 °C (p &lt;0.01). Para la velocidad lineal y media, la mayor proporción de subpoblaciones de miracidios eclosionados se observó a las 0 h, en el rango de 2 190 a 2 545 &#956;m s-1; mientras que para la velocidad curvilínea se observó la mayor proporción en el rango de 1 820 a 2 190 &#956;m s-1. Se observaron diferencias significativas entre el porcentaje de miracidios de las subpoblaciones y el tiempo post-eclosión de los huevos. La velocidad lineal y media de las subpoblaciones de miracidios mostraron diferencias en las temperaturas de incubación (p &lt; 0.01). Los datos sugieren que la temperatura de incubación de los huevos de F. hepatica tiene efecto en la motilidad del miracidio, lo que puede influir en la infectividad.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: The aim of this study was to evaluate the motility of Fasciola hepática miracidia subpopulations at different incubation temperatures and times post-hatching. Eggs were incubated at 22 °C or 25 °C for 14 d in complete darkness. Three parameters of velocity (curvilinear, straight-line and average path) and seven subpopulations were evaluated up to 10 h post-hatching. No significant differences were observed in the percentage of egg hatching after incubation with 91.7 % and 94,2 % hatching at 22 °C and 25 °C, respectively. The percentage of miracidia kinematic subpopulations after incubation at 22 °C was significantly different from that observed at 25 °C (p &lt; 0.01). The proportion of miracidia hatched for straight-line velocity (87.62 %) and average path velocity (84.95 %) were the highest in the category of 2190-2545 &#956;m s-1 at 0 h; while curvilinear velocity (49.09 %) was 1 820-2 190 &#956;m s-1. Significant differences among the percentage of miracidia subpopulations and times post-hatching of parasite eggs (p &lt;0.01). The straight-line velocity (87.62 %) and average path velocity (84.95 %) showed significant differences between 22 °C and 25 °C for the study period (p &lt; 0.01). The proportion of miracidia from different categories of straight-line velocity (87.62 %) and average path velocity (84.95 %) showed significant differences between 22 °C and 25 °C for the study period (p &lt; 0.01). The data suggest that the incubation temperature of Fasciola hepatica eggs have an effect on miracidium motility can influence the snail infectivity.]]></p></abstract>
