Little is known about exposure to diseases or the health of ice‐associated seals of the Bering Sea, which include ribbon (Histriophoca fasciata), spotted (Phoca largha), and bearded seals (Erignathus barbatus). To assess exposure to several pathogens, ribbon and spotted seals were sampled from the pack ice of the Bering Sea, and bearded seals were sampled in Kotzebue Sound, Alaska. Serum was tested for antibodies against phocine herpesvirus‐1 (PhHV‐1), phocine distemper virus (PDV), influenza A, Brucella spp., Coxiella burnetii, Leptospira interrogans, Toxoplasma gondii, and Sarcocystis neurona. Spotted seals were positive for antibodies to PhHV‐1 (76.6%), PDV (41.5%), influenza A (10.6%), Brucella spp. (9.5%), and Coxiella burnetii (8.3%); ribbon seals tested positive for PhHV‐1 (9.5%), PDV (41.2%), influenza A (4.8%), and Coxiella burnetii (8.0%); and bearded seals tested positive for PhHV‐1 (33.3%) and PDV (100%). All species were negative for antibodies to Leptospira interrogans, Toxoplasma gondii, and Sarcocystis neurona. Our study confirms that ice‐associated seals in Alaska have been exposed to at least five pathogens, some of which could pose health concerns for indigenous Arctic communities. We recommend continued monitoring to identify human health concerns and to monitor changes in seal health that might be exacerbated by effects of climate warming.

在白令海进行带状海豹（Histriophoca fasciata），斑海豹（Phoca largha）和大胡子海豹（Erignathus barbatus）中潜在病原体暴露的血清学调查

人们对白令海的疾病或冰相关海豹的健康状况知之甚少，其中包括丝带（Histriophoca fasciata），斑斑（Phoca largha）和胡须海豹（Erignathus barbatus）。为了评估对几种病原体的暴露程度，从白令海的ice冰中取样了带状和斑点海豹，并在阿拉斯加的Kotzebue Sound中取样了有胡须的海豹。血清测试针对海豹瘟疱疹病毒1（PhHV-1），海豹瘟热病毒（PDV），流感A，抗体布鲁氏菌属，贝氏柯克斯体，问号钩端螺旋体，弓形虫，和肉孢子虫neurona。斑点的密封对PhHV-1（76.6％），PDV（41.5％），A型流感（10.6％）和布鲁氏菌属的抗体呈阳性。（9.5％）和伯氏柯氏杆菌（8.3％）；带状密封条的PhHV-1（9.5％），PDV（41.2％），A型流感（4.8％）和Burnetii（8.0％）呈阳性; 以及有胡子的密封件的PhHV-1（33.3％）和PDV（100％）呈阳性。所有物种的钩端螺旋体，弓形虫和神经囊藻抗体均为阴性。。我们的研究证实，阿拉斯加的与冰相关的海豹已经接触了至少五种病原体，其中一些病原体可能对北极土著社区造成健康问题。我们建议继续进行监测，以发现人类健康问题，并监测气候变暖的影响可能加剧海豹健康的变化。
