Abstract：
Between 1898 and 1940, eight human cases of diphyllobothriasis were reported in Argentina, always in recently arrived European immigrants. In 1982, the first autochthonous case was detected, and since then, 33 other autochthonous cases have been reported, totaling 42 cases of human diphyllobothriasis in Argentina before the present study. Our aim is to update the information on diphyllobothriasis in Argentina by identifying specimens from new cases using morphometrical and/or molecular methods. We also aim to assess the epidemiological relevance of this food-borne disease in the country. Anamnestic data were obtained from patients or professionals, along with 26 worms identified using morphometrical (21 samples) and molecular techniques (5 samples). All the patients acquired the infection by consuming freshwater salmonids caught in Andean lakes in Northern Patagonia. Morphometrics and DNA markers of worms were compatible with Dibothriocephalus latus. In total, 68 human cases have been detected in Argentina, 60 of which were autochthonous. The human population living North-western Patagonia, whose lakes are inhabited by salmonids, is increasing. Similarly, the number of other definitive hosts for Dibothriocephalus dendriticus (gulls) and for D. latus (dogs) is also increasing. In addition, salmonid fishing and the habit of consuming home-prepared raw fish dishes are becoming widespread. Therefore, it is to be expected that diphyllobothriasis in Argentina will increase further.
摘要：
在1898年至1940年之间，阿根廷报告了8例人类双叶病病例，总是在最近到达的欧洲移民。1982年，发现了第一例本土病例，从那以后,已报告其他33例本地病例，在本研究之前，阿根廷共有42例人类二苯基病。我们的目标是通过使用形态计量学和/或分子方法从新病例中识别标本，来更新有关阿根廷双叶病的信息。我们还旨在评估这种食源性疾病在该国的流行病学相关性。记忆障碍数据来自患者或专业人士，以及使用形态计量学(21个样本)和分子技术(5个样本)鉴定的26个蠕虫。所有患者都是通过食用在巴塔哥尼亚北部安第斯湖中捕获的淡水鲑鱼而感染的。蠕虫的形态计量学和DNA标记与双头鱼兼容。总的来说,在阿根廷发现了68例人类病例，其中60个是土生土长的。居住在巴塔哥尼亚西北部的人口，他们的湖泊居住着鲑鱼，正在增加。同样，树状双头鱼（gulls）和D.latus（狗）的其他确定宿主的数量也在增加。此外,鲑鱼捕捞和食用自制生鱼菜肴的习惯越来越普遍。因此,预计阿根廷的双叶病将进一步增加。
