Elaphostrongylus cervi is a parasite of skeletal muscles and central nervous system of wild and farm red deer in Europe and Asia. Numerous species of terrestrial snails can be its intermediate hosts. Considering the fact that invasive larvae of E. cervi are released by deer to the external environment in huge numbers, fishes and birds can be accidentally infect by them. In this study the development of larvae E. cervi in those nonspecific hosts was discussed. It was determined that invasive larvae of E. cervi in the digestive tract of fish do not penetrate the intestinal wall, do not develop any further, and are probably digested. Similarly, those larvae given to chicken are also incapable of breaking the gut barrier and are digested. In all infected animals, the phenomenon of parathenia has not been observed and the meat of the animals studied poses not threat to humans.
鹿类圆线虫是欧洲和亚洲野生及养殖马鹿骨骼肌和中枢神经系统的一种寄生虫。许多陆生蜗牛种类可作为其中间宿主。鉴于鹿类圆线虫的侵袭性幼虫大量排放到外部环境中，鱼类和鸟类可能会意外感染。本研究探讨了鹿类圆线虫幼虫在这些非特异性宿主中的发育情况。结果表明，鱼类消化道内的鹿类圆线虫侵袭性幼虫不会穿透肠壁，不会进一步发育，可能会被消化。同样，给鸡投喂的那些幼虫也无法突破肠道屏障并被消化。在所有受感染动物中，未观察到孤雌生殖现象，所研究动物的肉对人类不构成威胁。
