Metacercariae of a North American digenean Posthodiplostomum cf. minimum centrarchi (Strigeiformes: Diplostomidae), have been reported from seven localities in Europe, with cysts recorded in the mesentery and internal organs of two invasive non-indigenous fishes (Lepomis gibbosus and Micropterus salmoides) from sites in Bulgaria, the Czech Republic and Portugal. Analysis of rDNA locus ITS1-ITS2-28S confirmed a closer relationship to the American Posthodiplostomum species than the common European species P. cuticola or P. brevicaudatum. Our data indicate limited potential of this parasite for switch to local fish fauna and confirm the occurrence at distant sites across Europe, suggesting that birds as definitive parasite hosts may play an important role for parasite dispersal. Further detailed studies are needed to confirm the actual means of introduction to Europe.
一种北美复殖吸虫——近似微小后双盘吸虫（Posthodiplostomum cf. minimum centrarchi，复殖目：双盘科）的囊蚴已在欧洲的七个地点被发现，在保加利亚、捷克共和国和葡萄牙的两个入侵非本地鱼类（驼背太阳鱼Lepomis gibbosus和大口黑鲈Micropterus salmoides）的肠系膜和内脏中记录到了囊肿。对核糖体DNA ITS1-ITS2-28S位点的分析证实，与美国的后双盘吸虫物种相比，它与常见的欧洲物种截形后双盘吸虫（P. cuticola）或短尾后双盘吸虫（P. brevicaudatum）的关系更为密切。我们的数据表明，这种寄生虫感染本地鱼类种群的可能性有限，并证实了其在欧洲各地不同地点的出现，这表明鸟类作为最终寄生虫宿主可能在寄生虫传播中发挥重要作用。需要进一步详细研究以确认其传入欧洲的实际途径。
