最早报导中国田鼠感染寄生虫的是1928年 Lee C.U.所进行的日本血吸虫感染试验。今次是进一步研究。中国田鼠和小白鼠体重约20克,30～40周龄。以每鼠腹腔内平均注射40条尾蚴为一组,每鼠平均皮肤接触感染尾蚴23条为一组,检查了排卵及死亡情况。腹腔内注射组约在感染后6周开始排卵,五粒粪块内每粒的最高虫卵数,中国田鼠为185～1207个(平均501个),小白鼠217～892个(平均455个),两者间没有差异。中国田鼠9例中,至40周死亡的3例,到60周死亡的2例,剩下的至84周仍然产卵。小白鼠8例中
Earliest reports of Chinese voles infecting parasites were conducted by Lee C. U. in 1928 for the infection of Schistosoma japonicum. This is a further study. Chinese voles and mice weighing about 20 grams, 30 to 40 weeks of age. An average of 40 cercariae were injected intraperitoneally into each rat. Twenty-three cercariae were exposed to each skin of an average mouse and the ovulation and mortality were examined. The intraperitoneal injection group started ovulation about 6 weeks after infection, and the highest number of eggs in each of the five fecal pellets was 185-1207 (average 501) and white rat (217 ~ 892) (455 on average) There is no difference between the two. Among the 9 Chinese vole mice, 3 died within 40 weeks and 2 died within 60 weeks. The remaining 84 days still lay eggs. In 8 mice
