title: The relationship between the density of Fasciola hepatica miracidia and the net rate of miracidial infections in Lymnaea truncatula.
abstract: Experimental studies on the dynamics of infection of Lymnaea truncatula by the miracidia of Fasciola hepatica show that there is a linear relationship between the net rate of attachment of miracidia to snail epithelium and the density of infective stages. The probability of a snail remaining uninfected after exposure to a single miracidium varies with the size class of the snail. Under the conditions of the experiment (temperature, 15 degrees C; exposure period, 30 min; water volume, 8 ml), the probability was 0.46-0.48, 0.27-0.26 and 0.13-0.19 for snail size classes, 0.5-2.9, 3.0-5.9 and 6.0-8.9 mm respectively.
