The endoscopic and histopathological findings detected in Sparus aurata experimentally infected with third-stage Anisakis larvae without intermediate host are evaluated and discussed. In six fish, live nematode larvae were introduced by gastroscopy into the stomach. The first observation by endoscope, 15 days after challenge, showed the presence of some larvae at the level of gastric mucosa. An explorative celioscopy, performed 60 days after challenge, showed haemorrhages and/or nodules on the gut of two fishes. Necropsy and histology demonstrated parasites in the context of the tissue changes. The finding of live nematode larvae as well as the evidence of tissue change confirm the experimental susceptibility of gilthead sea bream towards Anisakis.
本文评估和讨论了经第三期海兽胃线虫幼虫（无中间宿主）感染实验的真鲷的内镜和组织病理学发现。在 6 条鱼中，通过胃镜将活的线虫幼虫引入胃中。在挑战后 15 天进行的第一次内镜观察显示，胃黏膜处有一些幼虫。在挑战后 60 天进行的探索性剖腹检查显示，两条鱼的肠道有出血和/或结节。尸检和组织学检查显示寄生虫在组织变化的背景下存在。活线虫幼虫的发现以及组织变化的证据证实了真鲷对海兽胃线虫的实验易感性。
