Most of trematodes need snails to complete their life cycles. Consequently freshwater snails are served as intermediate hosts of many parasites worldwide. There is a lack of report on snail diversity and parasitic infection in snails in Sirindhorn Reservoir, Ubon Ratchathani province, Thailand.
Mollusk diversity and trematode cercariae infections were investigated in snails from 120 sampling sites surround Sirindhorn Reservoir from April 2018 to June 2018. Mollusk species were identified based on their shell morphology. The presence of cercariae infections in snails was examined by cercarial shedding methods. The interaction between snail species was analyzed by the correlation method.
Overall, 2076 mollusks were collected which comprised six species of snails and two species of bivalves. Snail species were identified as , and The overall rate of trematode cercariae infection was 1.69% (35/2,076). The cercariae found infecting snails were Cercariaeum cercaria, Virgulate cercaria, Cotylomicrocercous cercaria and Furcocercous cercaria. The most common snails found was the assassin snail, which showed the negative relationship among other species interactions.
This finding indicated infection with animal's parasites in snails in this area are common, besides, we found many species of snails in Sirindhorn Reservoir are potentially be the host of parasite in animal and human.
大多数吸虫需要蜗牛来完成其生命周期。因此，淡水蜗牛是全球许多寄生虫的中间宿主。泰国乌汶叻差他尼府诗琳通水库的蜗牛多样性和蜗牛体内的寄生虫感染情况尚无相关报道。
2018年4月至2018年6月，对诗琳通水库周边120个采样点的蜗牛进行了软体动物多样性和吸虫尾蚴感染情况调查。根据蜗牛壳的形态鉴定软体动物种类。采用尾蚴逸出法检测蜗牛体内尾蚴感染情况。用相关性方法分析蜗牛种类之间的相互作用。
共采集到2076只软体动物，包括6种蜗牛和2种双壳贝类。蜗牛种类鉴定为[具体种类未给出]。吸虫尾蚴感染的总体发生率为1.69%（35/2076）。感染蜗牛的尾蚴有尾蚴属尾蚴、丝状尾蚴、杯尾微尾蚴和叉尾尾蚴。发现最常见的蜗牛是杀手螺，其在其他物种相互作用中呈负相关关系。
这一发现表明该地区蜗牛感染动物寄生虫的情况很常见，此外，我们发现诗琳通水库中的许多蜗牛种类可能是动物和人类寄生虫的宿主。
