Abstract

Research highlights: Multiple independent HPAIV H5N1 euBB incursions occurred in Germany in 2023.HPAIV H5N1 euBB caused mass mortality in black-headed gulls and common terns.Outbreaks reduced gull and tern breeding populations by 16% and 6%, respectively.Rising H5-seroprevalence in terns may have contributed to the fade-out of genotype euBB.

2023年德国黑头鸥和普通候鸟中高致病性禽流感病毒H5N1，分支2.3.4.4b euBB的爆发动态

自2022/23年冬季以来，高致病性禽流感病毒（HPAIV） H5N1进化枝2.3.4.4b（基因型euBB）在野生鸟类中造成了广泛的死亡。该基因型于2022年春季在法国通过海鸥适应的低致病性病毒与HPAIV H5N1之间的重组出现。在这里，我们利用系统地理学分析、响铃数据和时空暴发模式信息，研究了德国黑头鸥（chricocephalus ridibundus）和普通候鸟（Sterna hirundo）基因型euBB的传播、病毒相关死亡率和种群水平影响。传播到德国繁殖地涉及多次独立入侵，可能与黑头鸥从荷兰、比利时和法国的越冬地返回有关。它蔓延到普通燕鸥，并导致2023年两个物种的成年死亡率很高（至少8137只黑头鸥和614只普通燕鸥，占繁殖种群的3%），随后在2024年繁殖对显著下降（黑头鸥-16%，普通燕鸥-6%）。免疫力的增强，至少在一般情况下，可能促成了基因型euBB随后的明显消退。这些发现强调了整合鸟类学、流行病学和病毒学数据如何帮助我们了解病毒传播途径和种群水平的影响，同时也强调了HPAIV应该被添加到海鸟的压力列表中，这一群体已经是全球所有鸟类分类群中最受威胁的群体。

期刊介绍： Avian Pathology is the official journal of the World Veterinary Poultry Association and, since its first publication in 1972, has been a leading international journal for poultry disease scientists. It publishes material relevant to the entire field of infectious and non-infectious diseases of poultry and other birds. Accepted manuscripts will contribute novel data of interest to an international readership and will add significantly to knowledge and understanding of diseases, old or new. Subject areas include pathology, diagnosis, detection and characterisation of pathogens, infections of possible zoonotic importance, epidemiology, innate and immune responses, vaccines, gene sequences, genetics in relation to disease and physiological and biochemical changes in response to disease. First and subsequent reports of well-recognized diseases within a country are not acceptable unless they also include substantial new information about the disease or pathogen. Manuscripts on wild or pet birds should describe disease or pathogens in a significant number of birds, recognizing/suggesting serious potential impact on that species or that the disease or pathogen is of demonstrable relevance to poultry. Manuscripts on food-borne microorganisms acquired during or after processing, and those that catalogue the occurrence or properties of microorganisms, are unlikely to be considered for publication in the absence of data linking them to avian disease.
