Abstract

Thirteen of 21 nestling bald eagles (Haliaeetus leucocephalus) examined for blood parasites in Michigan and Minnesota (USA) during June and July 1997 had patent infections of Leucocytozoon toddi. No other parasites were seen. The degree of parasitemia was light and varied from 1 to 2 on the Ashford Scale. Several of the infected nestlings appeared to have elevated levels of heterophils in their peripheral circulating blood. One of the infected nestlings also showed signs of severe anemia. We believe this is the first report of L. toddi in the bald eagle.

摘要

1997年6月和7月期间，在美国密歇根州和明尼苏达州对21只白头海雕雏鸟进行血寄生虫检查，其中13只感染了托氏白细胞原虫（Leucocytozoon toddi）。未发现其他寄生虫。寄生虫血症程度较轻，在阿什福德量表上为1至2级。几只受感染的雏鸟外周循环血液中的嗜中性粒细胞水平似乎有所升高。其中一只受感染的雏鸟还出现了严重贫血的症状。我们认为这是白头海雕感染托氏白细胞原虫的首次报告。
