We report malaria parasite infection ( Plasmodium spp.) and associated mortality in a Common Loon (Gavia immer) found dead on Lake Umbagog in New Hampshire, US. Necropsy findings showed the bird to be in good body condition but with pericardial edema and splenomegaly. Histopathological examination of brain and heart revealed intraendothelial and intrahistiocytic proliferation of Plasmodium merozoites with myocarditis. By PCR, the presence of Plasmodium parasites was confirmed from all tissues screened including spleen, muscle, and kidney. Sequencing of nested-PCR products revealed two different Plasmodium lineages, CATUST05 and PADOM11, indicating a mixed malaria parasite infection. Clinical findings strongly support malaria-induced mortality in a Common Loon.
我们报告了在美国新罕布什尔州昂巴戈格湖发现死亡的一只普通潜鸟（白嘴潜鸟）感染疟原虫（疟原虫属）及相关死亡情况。尸检结果显示这只鸟身体状况良好，但有心包水肿和脾肿大。对脑和心脏进行组织病理学检查发现，疟原虫裂殖子在内皮细胞内和组织细胞内增殖，并伴有心肌炎。通过聚合酶链反应（PCR），在包括脾脏、肌肉和肾脏在内的所有筛查组织中均证实存在疟原虫寄生虫。巢式PCR产物测序揭示了两种不同的疟原虫谱系，即CATUST05和PADOM11，表明存在混合疟原虫感染。临床发现有力地支持了普通潜鸟因疟疾导致死亡。
