在日本香川县捕获了129条蛇和33只黄鼠狼，对其幼虫进行了检测。从三条蛇和一条黄鼠狼身上发现了迄今为止未记载的幼虫，后来被鉴定为G. nipponium。实验完成了从卵到成虫的生命周期。独眼虫是第一个中间宿主，通过喂养它们从子宫卵中孵化的新幼虫来感染。我们从两只大鼠和一只小鼠身上获得了晚期三期幼虫，这两只大鼠和一只小鼠都摄入了早期三期幼虫。以大鼠晚期第三期幼虫为食的雪貂，在接触后100天食道肿瘤内出现成虫。
As only the adult of Gnathostoma nipponicum is known, 129 snakes and 33 weasels obtained in Kagawa Prefecture, Japan were examined for larvae. Hitherto undocumented larvae, later identified as G. nipponicum, were recovered from three snakes and one weasel. The life cycle was experimentally completed from eggs to adult worms. Cyclops, the first intermediate hosts, were infected by feeding them newly hatched larvae from uterine eggs. Advanced third-stage larvae were obtained from two rats and one mouse which had ingested early third-stage larvae from cyclops. A ferret fed advanced third-stage larvae from rats had adult worms in esophageal tumors 100 days after exposure.
