【摘要】 本实验为藐小棘隙吸虫尾蚴直接经口感染终宿主人、犬的可行性研究。9只幼犬分别喂以不同数量的尾蚴(4500～88000),并于感染后3.5h～34d分别解剖。结果:实验犬藐小棘隙吸虫感染率为100％,获虫率4.01％;感染后3.5b,部分尾蚴在胃中发育成囊蚴;8b,脱囊蚴虫在小肠内发现;13d,蚴虫发育成熟,虫卵在大便中检获。两自愿者分别感染尾蚴8400条和1500条,于感染后第15d、16d自粪中检获虫卵。提示人、畜生饮含有藐小棘隙吸虫尾蚴的水可致感染。更多还原

【Abstract】 This paper reports the experiment in which nine dogs and two volunteers were infected with Echinochasmus liliputanus cercariae (4 500 to 88 000) directly through mouth. The dogs were dissected 3.5 hours to 34 days after infection. The results showed. that all of nine dogs were infected and the worm recovery was 4.01%; the cercariae developed into metacerca■a in dog’s stomach 3.5 hours after infection: at the eighth hour after infection, juven■le were found in dog’s intestine: at the 13th day. juvenlle developed into adults and eggs were found in host’s stool. tn two volunteers faeces E. liliputanus eggs were found for the first time at 15th and 16th days respectively,■ suggests that humans and dogs can be infected through drinking raw water containing E. liliputanus cercariae.更多还原
