| 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 |
| larval trematode infections in freshwater gastropods from the albufera natural park in spain. | malacological samplings were made from january 1994 to december 1996 in the albufera natural park (valencia, spain) to trace the dynamics of molluscan populations and the prevalence and intensity of infection by larval trematodes. a total of 10,533 freshwater gastropods belonging to seven species (lymnaea auricularia, l. truncatula, l. palustris, l. peregra, bithynia tentaculata, physa acuta and gyraulus chinensis) was examined, and 110 (1.04%) were found to harbour some of the nine distinguisha ... | 1998 | 9639906 |
