极地鸟类体内不存在血液寄生虫被认为是一种普遍现象，但对真正的极地鸟类进行的调查却很少。我们检查了一种仅在北极地区繁殖的海鸟——小海雀（Alle alle）的血液寄生虫。聚合酶链反应用于检测血孢子虫，传统光学显微镜用于检测斯瓦尔巴群岛（挪威）繁殖的鸟类中更广泛的血虫。在检查的 100 只鸟中没有发现血液寄生虫。这一发现证实了极地地区血液的稀缺性，并为小海雀提供了基线数据。
Absence of blood parasites in birds occurring in polar regions is believed to be a common phenomenon but only few surveys have been conducted on truly polar bird species. We examined blood parasites in a seabird with an exclusively high-Arctic breeding distribution, the Little Auk (Alle alle). Polymerase chain reaction was used to detect haemosporidians and traditional optical microscopy was used to detect a wider range of haematozoans in birds breeding on Svalbard (Norway). No blood parasites were found among 100 birds examined. This finding confirms scarcity of haematozoa in polar regions and provides baseline data for the Little Auk.
