This is the first report of Ascocotyle (Phagicola) longa Ransom, 1920 (Digenea: Heterophyidae) in Argentina confirmed by morphological and molecular studies. The metacercaria was found encysted in myotomal musculature, heart and mesentery of the mullet Mugil liza (Pisces: Mugilidae) from Samborombon bay. We provide a morphological description of the metacercaria which we identified using species-specific primers for A. (Phagicola) longa and nucleotid sequence. This worldwide parasite has been reported as one of the causative agents of heterophyiosis, an emerging fish-borne disease of humans, contracted by the consumption of raw mullet. The discovery of A. (Phagicola) longa in Argentina represents a warning of the potentially great impact of this parasite on public health.
这是首次通过形态学和分子研究确认的阿根廷寄生在长棘海盘车（Phagicola）中的Ascocotyle（Phagicola）longa Ransom，1920（吸虫：异形科）。在来自桑博龙博湾的鲻鱼 Mugil liza（鱼：鲻科）的肌间肌肉、心脏和肠系膜中发现了囊尾蚴。我们提供了用针对 A.（Phagicola）longa 的种特异性引物和核苷酸序列鉴定的囊尾蚴的形态描述。这种世界性寄生虫已被报告为异嗜性的病原体之一，异嗜性是一种由食用生鲻鱼引起的人类新兴的鱼类传播疾病。在阿根廷发现长棘海盘车（Phagicola）longa 表明，这种寄生虫对公共卫生可能产生巨大影响。
