Wild aquatic birds serve as the natural reservoir for avian influenza virus (AIV), a disease with significant implications for avian and mammalian health. Climate change is predicted to impact the dynamics of AIV, particularly in areas such as the Arctic, but the baseline data needed to detect these shifts is often unavailable. In this study, plasma from two species of gulls breeding on the high-Arctic Svalbard archipelago were screened for antibodies to AIV.
AIV antibodies were found in black-legged kittiwake (Rissa tridactyla) samples from multiple years, as well as in glaucous gulls (Larus hyperboreous) samples.
Despite small sample sizes, evidence of exposure to AIV was found among Svalbard gulls. A wider survey of Svalbard avian species is warranted to establish knowledge on the extent of AIV exposure on Svalbard and to determine whether active infections are present.
野生水禽是禽流感病毒（AIV）的天然宿主，这种疾病对禽类和哺乳动物的健康都有重大影响。预计气候变化将影响 AIV 的动态，特别是在北极等地区，但检测这些变化所需的基线数据通常不可用。在这项研究中，对在高北极斯瓦尔巴群岛繁殖的两种海鸥的血浆进行了 AIV 抗体筛查。
在多年来的黑脚三趾鸥（Rissa tridactyla）样本以及大贼鸥（Larus hyperboreous）样本中发现了 AIV 抗体。
尽管样本量很小，但在斯瓦尔巴群岛的海鸥中发现了接触 AIV 的证据。有必要对斯瓦尔巴群岛的鸟类进行更广泛的调查，以确定在斯瓦尔巴群岛上 AIV 暴露的程度，并确定是否存在活跃的感染。
