Sheep given a primary infection of Fasciola hepatica were challenged 18 weeks later with Taenia hydatigena or F hepatica, or both parasites together, or were not challenged. At the same time, control sheep were infected with T hydatigena and/or F hepatica separately or concurrently. All sheep were killed seven weeks after challenge and the number of cysts and flukes counted. Challenge infection with T hydatigena did not affect the numbers of flukes recovered from either primary or challenge F hepatica infections. On the other hand, the numbers of cysticerci were reduced in sheep previously infected with F hepatica but not in those given T hydatigena and F hepatica concurrently.
给绵羊初次感染肝片吸虫，18周后用泡状带绦虫或肝片吸虫或两种寄生虫同时进行攻击感染，或者不进行攻击感染。同时，对照绵羊分别或同时感染泡状带绦虫和/或肝片吸虫。攻击感染7周后将所有绵羊宰杀，并对囊肿和吸虫的数量进行计数。用泡状带绦虫进行攻击感染并不影响从初次或再次感染肝片吸虫的绵羊体内回收的吸虫数量。另一方面，先前感染过肝片吸虫的绵羊体内的囊尾蚴数量减少，但同时感染泡状带绦虫和肝片吸虫的绵羊体内的囊尾蚴数量并未减少。
