An experiment was conducted to investigate the effects of experimental concurrent infection with Ostertagia ostertagia and Cooperia oncophora compared with the effects of monospecific infections with O ostertagi under conditions designed to mimic natural conditions on pasture during a grazing season. The present experiment was not able to demonstrate any significant effect of C oncophora on the course of an O ostertagi infection. Neither did C oncophora influence the build up of immunity to O ostertagi as demonstrated by post mortem worm count results from challenge infections with hypobiosis-prone larvae.
进行了一项实验，以研究在模拟放牧季节牧场自然条件的环境下，奥斯特他线虫（Ostertagia ostertagia）和牛古柏线虫（Cooperia oncophora）同时感染的实验效果，并与奥斯特他线虫单种感染的效果进行比较。本实验未能证明牛古柏线虫对奥斯特他线虫感染过程有任何显著影响。牛古柏线虫也未影响对奥斯特他线虫的免疫形成，这一点通过用易发生休眠的幼虫进行攻击感染后的尸检蠕虫计数结果得以证明。
