The prevalence of snail-borne trematode (SBT) infections in farm animals on the offshore Saint (St.) Martin's Island of Bangladesh were 68.9% for cattle, 76.7% for buffaloes, 56.3% for goats, respectively. Examination of fecal samples showed that paramphistomes infection was the most common at 50.5% followed by schistosomes at 23.7% and Fasciola at 2.3%. Fasciola infection was found in cattle (1.9%) and buffaloes (16.7%) but not in goats. Schistosome infection in cattle, buffaloes and goats were 31.1, 6.7 and 17.5%, respectively. Prevalence of SBTs was higher in older animals. Thiara tuberculata (Melanoides tuberculata) were found to serve as vector for paramphistomes and Indoplanorbis exustus for schistosomes and paramphistomes, respectively. Our results suggest that SBT and their vector snails are highly endemic on St. Martin's Island of Bangladesh, and proper attention is needed to control these infections.
在孟加拉国近海圣马丁岛的农场动物中，蜗牛传播的吸虫（SBT）感染率分别为：牛68.9%，水牛76.7%，山羊56.3%。粪便样本检查显示，同盘吸虫感染最为常见，占50.5%，其次是血吸虫，占23.7%，肝片吸虫占2.3%。肝片吸虫感染在牛（1.9%）和水牛（16.7%）中发现，但山羊未感染。牛、水牛和山羊的血吸虫感染率分别为31.1%、6.7%和17.5%。年龄较大的动物中SBT的感染率更高。发现瘤拟黑螺（Melanoides tuberculata）分别是同盘吸虫的传播媒介，而扁卷螺（Indoplanorbis exustus）分别是血吸虫和同盘吸虫的传播媒介。我们的结果表明，SBT及其传播媒介蜗牛在孟加拉国圣马丁岛高度流行，需要给予适当关注以控制这些感染。
