In two new attempts to infect human subjects with pin-worms that were infested, at that time, with protozoa Dientamoeba fragilis, presence of these protoza in the intestinal canal was observed in one case for more than 84 days, and in another case for more than 31 days after contamination. The duration of latent periods fixed for Enterobius vermicularis was almost identical (51 and 50 days). New attempts implement and confirm the results of the first successful attempts to transfer the infection (Ockert, 1972b) as well as the hypothesis of the epidemiological interrelation between both parasites (Burrows and Swerdlow 1956).
在两次新的尝试中，用当时感染了脆弱双核阿米巴原虫的蛲虫感染人体受试者，在一例中观察到这些原虫在污染后84天以上存在于肠道中，另一例中在污染后31天以上存在于肠道中。确定的蛲虫潜伏期几乎相同（51天和50天）。新的尝试实施并证实了首次成功传播感染尝试的结果（奥克特，1972b）以及两种寄生虫之间流行病学相互关系的假设（伯罗斯和斯韦德洛，1956）。
