作者用4～14周龄的大白鼠和金色田鼠为丝虫实验的终宿主,给予接种埃及伊蚊体内的感染期幼虫后,定期解剖动物,观察幼虫的发育情况,并在接种后55天开始每周检查末梢血液中微丝蚴的出现情况,其结果如下。一、彭亨丝虫在大白鼠体内的生长发育:在接种后9天,以动物皮肤和躯体内查见的雌、雄幼虫已发育为第四期幼虫。于第25天雄性幼虫进行第四次脱皮,有些幼虫正在脱鞘或已完成脱鞘,但在25～44天杀死的大白鼠中未查见幼虫,亦未见有第四次脱皮 The authors used 4-14 week-old white mice and golden vole for the final host of filamentous worm experiments. After inoculation of the infected larvae in Aedes aegypti, the animals were regularly dissected and observed for larval development and started 55 days after inoculation Weekly examination of peripheral blood microfilaria appearance, the results are as follows. First, the growth of Penaeid Worm in the body of rats: nine days after inoculation, the female and male larvae found in the animal’s skin and body have developed into the fourth larvae. On Day 25, male larvae were exfoliated for the fourth time, some of the larvae were exfoliated or were completely uncoated, but no larvae were seen in rats killed between 25 and 44 days and no fourth exfoliation
