The first US case of human nanophyetiasis that does not involve ingestion of raw or undercooked salmonid fishes is reported. The patient worked with highly infected fish. Hand contamination with the infectious metacercariae of the digenetic trematode Nanophyetus salmincola (family Troglotrematidae) occurred during the handling of fresh-killed, juvenile coho salmon, Oncorhynchus kisutch. Diagnosis of nanophyetiasis was based on the clinical findings of chronic diarrhea, nausea, abdominal discomfort, and a peripheral blood eosinophilia of 43% and was confirmed on finding characteristic bipolar eggs in a stool specimen. The patient rarely ate seafood products and never ate raw or cold smoked fish. He responded favorably to praziquantel and was asymptomatic after therapy.
据报道，美国出现首例非因摄入生的或未煮熟鲑科鱼类而感染的人类短小膜壳绦虫病病例。该患者从事与感染严重的鱼类相关工作。在处理刚杀死的幼年银大麻哈鱼（Oncorhynchus kisutch）时，其手部被双盘吸虫纲的短小膜壳绦虫（Nanophyetus salmincola，穴形科）感染性尾蚴污染。短小膜壳绦虫病的诊断依据为慢性腹泻、恶心、腹部不适的临床表现以及外周血嗜酸性粒细胞增多达43%，粪便标本中发现特征性双极虫卵进一步确诊。该患者很少食用海产品，从未食用过生鱼或冷熏鱼。他对吡喹酮反应良好，治疗后无症状。
