The intestinal distribution of Trichinella spiralis and Hymenolepis diminuta in rats was studied in single and concurrent infections. Results showed that the location of T. spiralis was not significantly changed in concurrent infections, but higher populations of T. spiralis in single and concurrent infections resulted in a posterior shift in position. Trichinella spiralis affected H. diminuta distribution significantly by causing a posterior shift in the position of scoleces and biomass and a loss of circadian rhythm. Infection with 4,000 T. spiralis larvae resulted in decreased tapeworm weight and fecundity, and destrobilation of H. diminuta from day 8 to 18 of the T. spiralis intestinal stage. Hymenolepis diminuta moved anteriorly to its preferred microhabitat as the T. spiralis intestinal stage decreased.
在大鼠中研究了旋毛虫和微小膜壳绦虫在单一感染和同时感染时的肠道分布情况。结果表明，在同时感染时旋毛虫的位置没有显著变化，但单一感染和同时感染时旋毛虫数量较多导致其位置向后偏移。旋毛虫通过引起头节位置和生物量向后偏移以及昼夜节律丧失，显著影响微小膜壳绦虫的分布。感染4000条旋毛虫幼虫导致绦虫重量和繁殖力下降，并且在旋毛虫肠道期的第8天至18天微小膜壳绦虫出现节片脱落。随着旋毛虫肠道期的缩短，微小膜壳绦虫向前移动至其偏好的微生境。
