Groups of four deer each were experimentally infected with larvae of Dictyocaulus (D.) eckerti (from fallow deer) or D. viviparus (from cattle) or D. filaria (from sheep), groups of four cattle each with D. viviparus or D. eckerti and groups of 4 lambs each with D. filaria or D. eckerti. The animals were daily examined coprologically following the 16th day post infectionem. The animals were slaughtered at different times and the lungs were dissected. With the exception of the infection of the sheep with D. eckerti from fallow deer, the mutual infections of the different hosts with the lungworm species became patent. Lungworms could be isolated. Fallow deer proved to be more susceptible to an infection with D. viviparus than cattle to an infection with D. eckerti. The large lungworms which naturally infest fallow deer and cattle, D. eckerti and D. viviparus respectively, can be distinguished according to the morphology of their mouth capsules, especially in the structure of the buccal ring. These features were also present after infection of the heterologous hosts.
将四头鹿分为一组，分别用埃氏网尾线虫（来自黇鹿）、胎生网尾线虫（来自牛）或丝状网尾线虫（来自绵羊）的幼虫进行实验性感染；将四头牛分为一组，分别用胎生网尾线虫或埃氏网尾线虫感染；将四只羔羊分为一组，分别用丝状网尾线虫或埃氏网尾线虫感染。在感染后第16天起，每天对动物进行粪便检查。在不同时间宰杀动物并解剖肺部。除了用来自黇鹿的埃氏网尾线虫感染绵羊外，不同宿主之间的肺线虫交叉感染均出现了明显症状，且能分离出肺线虫。结果表明，黇鹿对胎生网尾线虫感染的易感性高于牛对埃氏网尾线虫感染的易感性。分别自然感染黇鹿和牛的大型肺线虫，即埃氏网尾线虫和胎生网尾线虫，可根据其口囊形态，特别是颊环结构进行区分。在异种宿主感染后，这些特征依然存在。
