In order to establish the mammalian parasitic cycle of the nematode Neostrongylus linearis 18 lambs were infected with 5000 third-stage larvae obtained from the snail Cernuella (Xeromagna) cespitum arigonis. In the subsequent days, larvae were found in the walls of the caecum and colon, in the liver and the lungs, suggesting that the bloodstream is the main migratory route. The presence of low numbers of migrating larvae in the mesenteric lymph nodes indicates that this route is probably secondary. The first still sexually undifferentiated, fourth-stage larvae were found in the lungs on the 8th day post-infection (p.i.) and the first sexually differentiated fifth-stage larvae, on the 10th day. Also described are the macroscopic changes of the parasitized organs.
为了建立线虫线性新圆线虫的哺乳动物寄生循环，18只羔羊被感染了从蜗牛阿里戈尼斯园圃田螺获得的5000条第三期幼虫。在随后的日子里，在盲肠和结肠壁、肝脏和肺中发现了幼虫，这表明血流是主要的迁移途径。肠系膜淋巴结中存在少量迁移幼虫表明这条途径可能是次要的。在感染后第8天（p.i.）在肺中发现了第一批仍未性分化的第四期幼虫，在第10天发现了第一批性分化的第五期幼虫。还描述了被寄生器官的宏观变化。
