In view of the amateur fishing practices and the importance of salmonids in the region the study sets out to detect human hosts in the Andean-Patagonian zone.
Information campaigns were carried out by Clinical Analysis Laboratories of Andean Patagonia between 1986 and 1995 to detect diphyllobothriasis more efficiently by means of coproparasitological analysis.
Further, forms were prepared for the collection of information about infection, treatment and the characteristics of the human host. During this period 13 new cases were registered either through direct identification of the parasite or through the presence of eggs in the faeces. The characteristics of infection are similar to those described for the genus Diphyllobothrium.
The favourite game fish in Andean Patagonia are salmonids. This fish, often infected with plerocercoids, when eaten insufficiently cooked or cold smoked, constitutes the main source of human infection.
鉴于该地区业余捕鱼活动以及鲑科鱼类的重要性，本研究旨在检测安第斯 - 巴塔哥尼亚地区的人类宿主。
1986年至1995年间，安第斯巴塔哥尼亚临床分析实验室开展了宣传活动，通过粪便寄生虫学分析更有效地检测阔节裂头绦虫病。
此外，还准备了表格用于收集有关感染、治疗及人类宿主特征的信息。在此期间，通过直接鉴定寄生虫或粪便中存在虫卵，共记录了13例新病例。感染特征与阔节裂头绦虫属所描述的特征相似。
安第斯巴塔哥尼亚最受欢迎的游钓鱼类是鲑科鱼类。这种鱼常感染裂头蚴，食用未充分煮熟或冷熏的鱼肉时，是人类感染的主要来源。
