两名意大利妇女因食用了生凤尾鱼（engrulis encrasicolus）而发生胃异丝蚴病。第一位患者为一名49岁女性，在食用腌制（醋）生凤尾鱼后出现胃痛和带血呕吐。在食管胃十二指肠镜检查（EGDS）中发现一条白色的蠕虫，并通过活检钳从贲门取出。第二例患者为患有肠易激综合征和胃炎的59岁女性，接受了周期性egds。在最后一次EGDS过程中，胃窦可见白色圆虫，胃底可见小息肉。光镜下鉴定为异尖线虫属L3幼虫，聚合酶链反应-限制性片段长度多态性鉴定为pegreffi异尖线虫属。在物种水平上病原的分子鉴定可以确定哪些异角虫科物种起人畜共患病作用，哪些是鱼类宿主物种。
Two cases of gastric anisakiasis have been documented in two Italian women who had consumed raw anchovies (Engraulis encrasicolus). The first patient was a 49-year-old woman presenting with epigastric pain and bloody vomiting after ingestion of marinated (vinegar) raw anchovies. During the esophagogastroduodenoscopy (EGDS) a white color worm was detected and extracted from cardia by means of biopsy forceps. The second patient was a 59-year-old woman with irritable bowel syndrome and gastritis, who underwent to periodical EGDSs. In the course of the last EGDS, a white color round worm on antrum and a small polyp on the fundus of the stomach were observed. The two nematodes have been identified as L3 larvae of the genus Anisakis by a light microscope, and as Anisakis pegreffi by polymerase chain reaction-restriction fragment length polymorphism. The molecular identification of the etiological agent at the species level allows to identify what Anisakidae species play a zoonotic role and which are the fish host species.
