Abstract

Highly pathogenic H5N1 influenza A virus (HP H5N1) cases in wild mammals have been increasing globally. Carnivora has been the most affected mammal order; however, the extent of morbidity and mortality in carnivores exposed to HP H5N1 remains undefined. We assessed the presence of antibodies to H5 and N1 in the sera of 16 live-captured bobcats (Lynx rufus) in New York State, USA; reported on postcapture outcomes of HP H5N1-exposed bobcats; and reported on a case of HP H5N1 infection in one bobcat. In 2024, 4/16 bobcats (25%) tested positive for antibodies to H5 and N1. Two bobcats were confirmed alive as of November 2024 according to GPS data; the other two were alive as of June 2024, when their GPS collars stopped communicating. Another bobcat, which was negative for HP H5N1 antibodies at capture, died from HP H5N1 infection within 5 wks of capture. Our results provide evidence of bobcats both surviving and succumbing to HP H5N1 infection and highlight the importance of focused health studies paired with monitoring data to better understand exposure, infection, and outcomes for novel pathogens and species.

美国纽约自由放养山猫（Lynx rufus）的高致病性禽流感病毒暴露和感染。

全球野生哺乳动物高致病性H5N1甲型流感病毒（HP H5N1）病例呈上升趋势。食肉目是受影响最大的哺乳动物目；然而，暴露于HP H5N1的食肉动物的发病率和死亡率程度仍未确定。我们评估了美国纽约州16只活捕获的山猫（Lynx rufus）血清中H5和N1抗体的存在；报告了暴露于HP h5n1的山猫捕获后的结果；并报告了一只山猫感染H5N1型禽流感病例。2024年，4/16（25%）山猫检测出H5和N1抗体阳性。根据GPS数据，截至2024年11月，其中两颗被确认活着；另外两人在2024年6月还活着，当时他们的GPS项圈停止了通信。另一只山猫在捕获时HP H5N1抗体呈阴性，在捕获后5周内死于HP H5N1感染。我们的研究结果提供了山猫在HP H5N1感染中存活和死亡的证据，并强调了重点卫生研究与监测数据相结合的重要性，以更好地了解新病原体和新物种的暴露、感染和结果。

期刊介绍： The JWD publishes reports of wildlife disease investigations, research papers, brief research notes, case and epizootic reports, review articles, and book reviews. The JWD publishes the results of original research and observations dealing with all aspects of infectious, parasitic, toxic, nutritional, physiologic, developmental and neoplastic diseases, environmental contamination, and other factors impinging on the health and survival of free-living or occasionally captive populations of wild animals, including fish, amphibians, reptiles, birds, and mammals. Papers on zoonoses involving wildlife and on chemical immobilization of wild animals are also published. Manuscripts dealing with surveys and case reports may be published in the Journal provided that they contain significant new information or have significance for better understanding health and disease in wild populations. Authors are encouraged to address the wildlife management implications of their studies, where appropriate.
