摘要
通过本试验证实土耳其斯坦东毕吸虫在终末宿主体内发育是:尾蚴侵入皮肤后至第5天皮肤内发现童虫,其中1.5～2.5天皮内童虫最多,并在2.5天开始向肺组织移行,至第6.5天肺组织内发现较多童虫,第8.5天肺组织内童虫数明显减少,并开始向肝脏的静脉管移行。在感染后第12.5天,肺组织内已找不到童虫,肝脏内可找到大量童虫。在感染后22.5天,大量童虫定居在肝脏的门静脉和肠系膜静脉内,同时发现部分配偶合抱的虫体。其结果表明:土耳其斯坦东毕吸虫的移行路线是由皮肤侵入后经静脉管入肺静脉后又随血循环进入肝脏,最终定居肝门静脉和肠系膜静脉,这与日本血吸虫的移行路线基本相同。
Radix auricularia and R. ovata being infected with miracidium of O. turkestanica, when the miracidium became cercaria in Radix and went out from the Radix, rabbits, goats and sheep were infected with cercariae percutaneously. By anatomical examination, it was found that the path of migration of O. turkestanica was that cercaria invaded into animals percutaneously as soon as it entered the venous vessel and pulmonary vein, then reached liver, following blood circulation and finally settled down in hepatic portal vein and mesenteric vein. The morphological characteristics of each developmental stage of the larva were described
