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 and the rhythm of daily cercarial production. However, a significantly higher total cercarial production per snail, patent period and life span were observed in local snails. The different infection characteristics in the three G. chinensis strains considered reveal that E. albuferensis miracidia demonstrate local adaptation.
以棘口吸虫毛蚴感染同域或“本地”与异域或“外地”蜗牛组合进行实验性感染，以此作为检验寄生虫兼容性的模型。我们使用阿尔布费拉真缘吸虫毛蚴感染来自三个不同自然公园的中华圆田螺：阿尔布费拉（西班牙巴伦西亚）；埃布罗三角洲（西班牙塔拉戈纳）和多尼亚纳国家公园（西班牙韦尔瓦）。在感染率和每日尾蚴产出节律方面，三种蜗牛品系之间差异不显著。然而，在本地蜗牛中观察到每只蜗牛的尾蚴总产出量、感染期和寿命显著更高。所考虑的三种中华圆田螺品系的不同感染特征表明，阿尔布费拉真缘吸虫毛蚴表现出本地适应性。
