Between 1988 and 2004, postmortem examinations were carried out on 445 otters found dead, mostly as a result of road traffic accidents, in southern and south-west England. Thickened, shrunken gall bladders were observed in 10 cases, the first in 2000 and the others between February 2002 and August 2004. A digenean fluke, Pseudamphistomum truncatum, was found in the gall bladders of three cases and also in three of seven American mink examined. Nine of the 10 otters and all the mink came from a localised area of Somerset, indicating that the fluke has become established in the local fish population. P. truncatum has not been recorded previously in Britain, and the results suggest that it has been introduced recently, possibly in imported fish.
1988年至2004年间，对在英格兰南部和西南部发现死亡的445只水獭进行了尸检，其中大部分死于道路交通事故。在10例水獭中观察到胆囊增厚、萎缩，首例发生于2000年，其他病例发生于2002年2月至2004年8月之间。在3例水獭的胆囊中发现了一种复殖吸虫——截形伪双盘吸虫，在7只接受检查的美国水貂中也有3只发现了这种吸虫。10只水獭中有9只以及所有水貂均来自萨默塞特郡的一个局部地区，这表明这种吸虫已在当地鱼类种群中定殖。截形伪双盘吸虫此前在英国尚未有记录，研究结果表明它可能是最近随着进口鱼类传入的。
