| sympatric and allopatric experimental infections of the planorbid snail gyraulus chinensis with miracidia of euparyphium albuferensis (trematoda: echinostomatidae). | an experimental infection with echinostomatid miracidia in sympatric or 'local' vs. allopatric or 'away' snail combinations, as a model to examine parasite compatibility, was carried out. we employed euparyphium albuferensis miracidia to infect gyraulus chinensis snails, from three different natural parks: albufera (valencia, spain); the ebro delta (tarragona, spain) and coto de doñana (huelva, spain). insignificant differences between the three snail strains were noted for the infection rate an ... | 2010 | 20236558 |
