Dreyfuss, G., Vignoles, P., Rondelaud, D., and Vareille-Morel, C. 1999.Fasciola hepatica: Characteristics of infection inLymnaea truncatulain relation to the number of miracidia at exposure.Experimental Parasitology92, 19–23. Experimental infections ofLymnaea truncatulabyFasciola hepaticawere carried out in three snail populations to determine whether the number of miracidia used for each snail at exposure (1, 2, 5, 10, or 20 per snail) had any influence on the characteristics ofFasciolainfection and metacercarial production. The number of miracidia had a significant influence on snail survival at day 30 postexposure and the frequency of infectedL. truncatulathat died without shedding (NCS snails). The frequency of NCS snails, the growth of cercaria-shedding snails throughout the experiment, the time between exposure and the first cercarial shedding, the duration of shedding, and the number of metacercariae were independent of the number of miracidia used for each snail. The highest metacercaria productivity for each miracidium was found in single-miracidium infections. Single-miracidium infections were the most effective, as the mean number of cercariae was the same as in other groups, whereas their survival rate was much higher.
