Alveolar and cystic echinococcosis are emerging and reemerging in Europe, Africa, and Asia. The expansion of Echinococcus spp. tapeworms in wildlife host reservoirs appears to be driving this emergence in some areas. Recent studies suggest a similar phenomenon may be occurring in North America. We describe the context of Echinococcus spp. research in North America, with a specific focus on the contiguous United States. Although studies were conducted in the United States throughout the 1900s on various sylvatic and domestic Echinococcus spp. tapeworm cycles, data are lacking for the past ≈30 years. We review previous research, provide analysis of more recent focal studies, and suggest that Echinococcus spp. tapeworms, in particular E. canadensis, may be underrecognized. As a result, we suggest that additional research and surveillance be conducted for these tapeworms in wildlife host reservoirs across the United States.
肺泡和包虫病正在欧洲、非洲和亚洲出现和重现。在一些地区,棘球绦虫属绦虫在野生动物宿主中的扩张似乎推动了这种出现。最近的研究表明,北美的情况可能类似。我们描述了北美的棘球绦虫属研究背景,特别关注毗邻的美国。尽管在整个 20 世纪,美国都在各种森林和家养的棘球绦虫属绦虫循环中进行了研究,但过去 ≈30 年的数据却缺乏。我们回顾了以前的研究,对最近的重点研究进行了分析,并提出棘球绦虫属绦虫,特别是 E. canadensis,可能被低估了。因此,我们建议在美国野生动物宿主中对这些绦虫进行更多的研究和监测。
