[The structural changes of the kidney in Lymnaea truncatula Müller infected by Fasciola hepatica L].

The kidney of Lymnaea truncatula showed structural changes when infected by Fasciola hepatica. These changes first occurred at day 21 postexposure at 20 degrees C and concerned a destruction of renal epithelial cells followed by an epithelial hyperplasia. These hyperplasied epithelial cells again showed a destruction at days 49 and 70 post-exposure. The significance of these results is discussed.
