Comparative study on effectiveness of intravenous and subcutaneous methods of infection of animals has shown that infection rate of helminths after the injection of equal dozes of cercariae under skin, into portal and femoral veins of golden hamsters does not differ significantly (42.6 +/- 4.2, 37.8 +/- 5.8 and 26.0 +/- 6.6 schistosomes, respectively). When using the above methods for cotton rats the infection rate was lower than that in golden hamsters. The most insignificant infection rate of parasites was recorded in both species after the injection of cercariae into the femoral vein. Results of the infection of golden hamsters with different dozes of cercariae have shown that with the increase of dozes of infectious material the infection rate of helminths rises during the experimental intestinal schistosomiasis only to a definite level, which is attained by the injection of cercariae into the portal vein in dozes lower than those used for subcutaneous infection.
对动物进行静脉注射和皮下注射感染方法的有效性比较研究表明，在给金黄仓鼠的皮肤下、门静脉和股静脉注射等量尾蚴后，蠕虫的感染率没有显著差异（分别为42.6±4.2、37.8±5.8和26.0±6.6条血吸虫）。当对棉鼠使用上述方法时，感染率低于金黄仓鼠。在将尾蚴注射到股静脉后，两种动物的寄生虫感染率最低。用不同剂量尾蚴感染金黄仓鼠的结果表明，在实验性肠道血吸虫病中，随着感染物质剂量的增加，蠕虫的感染率仅上升到一定水平，通过向门静脉注射低于皮下感染所用剂量的尾蚴即可达到这一水平。
