Abstract：
UNASSIGNED: Lymnaea gedrosiana snails are hosts to a variety of trematode cercaria of public and veterinary health importance. In Guilan Province, Iran, a region with a high level of fish and bird farming and wetlands important for migratory birds, little is known about the trematode cercaria from L. gedrosiana.
UNASSIGNED: From April 2020 to October 2021, six freshwater sites in Guilan Province were sampled for Lymnaeidae snails three times per season (spring, summer, autumn and winter). Snails were exposed to light and heat to induce cercaria shedding and shredded cercaria were identified morphologically and molecularly.
UNASSIGNED: In total, 5,712 Lymnaeidae snails were collected of which 3,288 (57.6%) were identified to be L. gedrosiana with 54.3% containing trematode cercaria. Snail and cercaria recovery were highest in the spring and summer. Trematode cercaria identified included Telorchis assula, Hypoderaeum conoideum, Apharyngostrigea pipientis, Sanguinicola cf. inermis, Opisthioglyphe ranae, Diplostomum pseudospathaceum, and Australapatemon burti.
UNASSIGNED: The four trematodes D. pseudospathaceum, S. inermis, A. burti, and A. pipientis have not been previously reported in Iran; all four of these can infect migratory birds. The most common cercaria found, H. conoideum (18.3% of the snails) is of zoonotic importance. The third most common cercaria found, S. inermis (10.0% of the snails) is detrimental to fish production. Given the importance of the wetlands in the region for wildlife and migratory birds as well as the number of fish and bird farms in the area, efforts to control L. gedrosiana snails are needed to protect wildlife and human health. In addition, monitoring programs should be implemented to identify and prevent introductions of new trematode species.

摘要：
■Lymnaeagedrosiana蜗牛是各种具有公共和兽医健康重要性的吸虫尾蚴的寄主。在纪兰省,伊朗,一个鱼类和鸟类养殖水平高的地区和对候鸟重要的湿地，对L.gedrosiana的吸虫尾蚴知之甚少。
■从2020年4月到2021年10月，每个季节三次对桂兰省的六个淡水地点进行了Lymnaeidae蜗牛的采样（春季，夏天,秋季和冬季）。将蜗牛暴露于光和热中以诱导尾c脱落，并在形态和分子上鉴定了切碎的尾c。
■总共，收集了5,712只Lymnaeidae蜗牛，其中3,288只（57.6％）被鉴定为gedrosiana，其中54.3％含有吸虫尾蚴。蜗牛和尾蚴的恢复在春季和夏季最高。确定的吸虫尾蚴包括Telorchisassula，球藻底壳,咽喉炎，Sanguinicolacf.inerminis,拉马丝，假双足口，和澳大利亚伯蒂。
■四个吸虫D.S、inermis，A.Burti,和A.pipientis以前从未在伊朗报道过；所有这四种都可以感染候鸟。发现的最常见的尾蚴,H.conoideum（占蜗牛的18.3％）具有人畜共患的重要性。发现的第三个最常见的尾蚴，S.inermis(10.0%的蜗牛)对鱼类生产有害。鉴于该地区湿地对野生动物和候鸟的重要性，以及该地区鱼类和鸟类养殖场的数量，为了保护野生动物和人类健康，需要努力控制gedrosiana蜗牛。此外,应实施监测计划，以识别和防止引入新的吸虫物种。
