AbstractSingle and double infections of juvenile Omphiscola glabra (Gastropoda: Lymnaeidae) with Paramphistomum daubneyi and/or Fasciola hepatica were carried out to determine the redial burden and cercarial production in snails dissected at day 60 or at day 75 post-exposure (p.e.) in the laboratory at 20°C. The results were compared with those obtained with single-miracidium infections by Fascioloides magna. Compared to F. hepatica, low values were noted at day 75 p.e. for the prevalence of snail infections with P. daubneyi (4.6–8.3% instead of 23.6–25.9%), the total number of free rediae (10.7–17.9 per snail instead of 26.3–34.7), and that of free cercariae (112.8–136.9 per snail instead of 177.8–248.5). Despite a greater number of free rediae at day 75 p.e. (36.2–45.6 per snail), the prevalences of snail infections with F. magna and cercarial production were similar to those noted for F. hepatica. The results concerning F. hepatica and P. daubneyi might partly be explained by a progressive adaptation of O. glabra to sustain the larval development of these digeneans over the years, as this snail is a natural intermediate host of F. hepatica and P. daubneyi in central France since 1995. Compared with the high number of fully-grown rediae of F. magna in O. glabra, cercarial production seemed limited and this might be explained by the presence of high numbers of rediae which reduced the avaibility of nutrients for cercarial differentiation within the snail.

AbstractRediae and immature cercariae of the giant liver fluke, Fascioloides magna, a pathogenic and important parasite of game animals, were found in 6 out of 7,277 Radix peregra (Gastropoda, Lymnaeidae) from two localities in Western and Central Bohemia, Czech Republic. In one of these localities a relatively high infection of Galba truncatula (26 out of 76) with mature cercariae of F. magna was detected. R. peregra, which is dominant over Galba truncatula, has never been reported as the natural intermediate host of F. magna. Its potential susceptibility to F. magna infection was confirmed experimentally with 67 snails of R. peregra (out of 371) infected. The present data indicate the capability of F. magna to expand the spectrum of its intermediate hosts and demonstrate the potential epizootiological importance of lymnaeid snails, other than G. truncatula, for transmission of the parasite in Europe.
