Fishborne trematode (FBT) metacercariae were investigated in fish from 3 Provinces of Lao PDR. Total 242 freshwater fish of 40 species were collected in local markets of Luang Prabang (59 fish of 16 species), Khammouane (81 fish of 19 species), and Saravane (97 fish of 14 species), and each of them was examined by artificial digestion method. Four species of metacercariae (Opisthorchis viverrini, Haplorchis taichui, Haplorchis yokogawai, and Centrocestus formosanus) were detected. O. viverrini was detected in 35 fish (14.5%), and their density was 252 per infected fish (Luang Prabang, 88 metacercariae in 5 fish; Khammouane, 187 in 6 fish; Saravane, 303 in 24 fish). H. taichui was found in 102 fish (42.1%), and their density was 485 per infected fish (Luang Prabang, 260 metacercariae in 38 fish; Khammouane, 1,084 in 23 fish; Saravane, 359 in 41 fish). H. yokogawai was detected in 92 fish (38.0%), and their density was 222 per infected fish (Luang Prabang, 362 metacercariae in 17 fish; Khammouane, 126 in 20 fish; Saravane, 214 in 55 fish). Metacercariae of C. formosanus were found in 8 fish (3.3%), and their density was 3 per infected fish. In the present study, it has been confirmed that FBT metacercariae, in particular, H. taichui, H. yokogawai, and O. viverrini, are highly prevalent in fish from Luang Prabang, Khammouane, and Saravane Province, Lao PDR.
对老挝人民民主共和国3个省的鱼类体内的食源性吸虫（FBT）囊蚴进行了调查。在琅南塔（16种59条鱼）、甘蒙（19种81条鱼）和沙拉湾（14种97条鱼）的当地市场共采集了40种242条淡水鱼，并采用人工消化法对每条鱼进行检查。检测到4种囊蚴（湄公河华支睾吸虫、太氏单睾吸虫、横川后殖吸虫和台湾棘带吸虫）。检测到35条鱼感染湄公河华支睾吸虫（14.5%），每条感染鱼的囊蚴密度为252个（琅南塔，5条鱼中有88个囊蚴；甘蒙，6条鱼中有187个；沙拉湾，24条鱼中有303个）。检测到102条鱼感染太氏单睾吸虫（42.1%），每条感染鱼的囊蚴密度为485个（琅南塔，38条鱼中有260个囊蚴；甘蒙，23条鱼中有1084个；沙拉湾，41条鱼中有359个）。检测到92条鱼感染横川后殖吸虫（38.0%），每条感染鱼的囊蚴密度为222个（琅南塔，17条鱼中有362个囊蚴；甘蒙，20条鱼中有126个；沙拉湾，55条鱼中有214个）。检测到8条鱼感染台湾棘带吸虫（3.3%），每条感染鱼的囊蚴密度为3个。在本研究中，已证实食源性吸虫囊蚴，特别是太氏单睾吸虫、横川后殖吸虫和湄公河华支睾吸虫，在老挝人民民主共和国琅南塔省、甘蒙省和沙拉湾省的鱼类中高度流行。
