Larval ascarid nematodes recently discovered in fresh salmon were identified as Anisakis larval Type I, this roundworm is the etiologic agent of anisakiasis, a parasitic disease characterized by eosinophilic granulomas affecting the human gastrointestinal tract. Infection may occur following ingestion of raw or poorly cooked fish. Patients generally present with an acute abdominal syndrome mimicking a wide variety of clinical conditions, thus creating a diagnostic dilemma. Unselected samples of fresh salmon tested by the University of Michigan Clinical Microbiology Laboratory and School of Public Health were all infected, the mean worm burden calculated as 79.3 larvae per kilogram of fish. The significance of this infection and the implications for morbidity in the United States are discussed.
最近在新鲜三文鱼中发现的幼虫蛔虫线虫被鉴定为Ⅰ型异尖线虫幼虫，这种蛔虫是异尖线虫病的病原体，这是一种寄生虫病，其特征是嗜酸性肉芽肿影响人类胃肠道。摄入生的或未煮熟的鱼后可能会发生感染。患者通常表现出类似多种临床病症的急性腹部综合征，从而造成诊断难题。密歇根大学临床微生物学实验室和公共卫生学院对未经挑选的新鲜三文鱼样本进行检测，发现所有样本均受到感染，每公斤鱼的平均虫负荷量经计算为79.3条幼虫。本文讨论了这种感染的重要性及其对美国发病率的影响。
