调查了老挝沙湾拿吉省居民的肝和肠吸虫感染的患病率。从湄公河滨江4个村庄共981名居民中采集粪便标本，并采用Kato-Katz厚涂片技术进行检查。结果显示，总的寄生虫卵阳性率为84.2%，其中小吸虫卵阳性率为67.1%。为了获得成虫吸虫，38例小吸虫卵阳性病例用吡喹酮20-30 mg/kg单剂量治疗并清除。然后收集了29人的腹泻粪便，并使用立体显微镜寻找蠕虫寄生虫。混合感染O.结果表明，共发现10种肝吸虫，其中包括肝吸虫、横川肝吸虫、棘口吸虫、小肝吸虫等6种。收集的吸虫总数为7，693个标本（平均值）。每名接受治疗人士的人数; 265.3）。最常见的种类是O. viverrini，其次为H. taichui，P. molenkampi，棘口线虫H. pumilio、P. bonnei和H.横河。结果表明，食源性肝和肠吸虫感染流行的沙湾拿吉省，老挝的居民。
The prevalence of liver and intestinal fluke infections was surveyed on residents of Savannakhet Province, Laos. Fecal specimens were collected from a total of 981 residents in 4 Mekong riverside villages and examined by the Kato-Katz thick smear technique. The results revealed that the overall helminth egg positive rate was 84.2%, and the positive rate for small trematode eggs, including Opisthorchis viverrini, heterophyids, or lecithodendriids, was 67.1%. To obtain adult flukes, 38 small trematode egg positive cases were treated with a 20-30 mg/kg single dose of praziquantel and purged. Diarrheic stools were then collected from 29 people and searched for helminth parasites using stereomicroscopes. Mixed infections with O. viverrini and 6 kinds of intestinal flukes were found, namely, Haplorchis taichui, Haplorchis pumilio, Haplorchis yokogawai, Prosthodendrium molenkampi, Phaneropsolus bonnei, and echinostomes. The total number of flukes collected was 7,693 specimens (av. no. per treated person; 265.3). The most common species was O. viverrini, followed by H. taichui, P. molenkampi, echinostomes, H. pumilio, P. bonnei, and H. yokogawai. The results indicate that foodborne liver and intestinal fluke infections are prevalent among residents of Savannakhet Province, Laos.
