The white-tailed eagle, , has been involved in the life cycle of several species as the intermediate and definitive host. To date, it has been supposed that the eagle might play the role as the definitive host for . , and, herein, we tried to elucidate it based on morphometric and molecular analyses. One out of two eagles harbored oocysts (17.0-17.4 × 11.3-11.9 μm) and sporocysts (11.3-12.3 × 8.3-9.3 μm) in the intestinal mucosa, whose sequences at rRNA, rRNA, ITS1, and showed similar identity (97.64-100%) to published sequences of . from other hosts. The presence of sporulated oocysts in the lamina propria of villi confirms that . truly infects the white-tailed eagle. The white-tailed eagle is confirmed as the definitive host of . in the Czech Republic.
白尾海雕作为中间宿主和终末宿主参与了几种物种的生命周期。迄今为止,人们认为该海雕可能是[某种寄生虫]的终末宿主。因此,在此我们试图通过形态计量学和分子分析来阐明这一点。两只海雕中有一只在肠黏膜中含有卵囊(17.0 - 17.4×11.3 - 11.9μm)和子孢子囊(11.3 - 12.3×8.3 - 9.3μm),其核糖体RNA、核糖体RNA、内转录间隔区1和[另一段基因名称]的序列与已发表的来自其他宿主的[该寄生虫名称]序列显示出相似的同一性(97.64 - 100%)。绒毛固有层中孢子化卵囊的存在证实[该寄生虫]确实感染了白尾海雕。在捷克共和国,白尾海雕被确认为[该寄生虫]的终末宿主。
