A viromics study on the intestinal contents of migratory wild ducks of the genera Anas, Mareca, Spatula, and Oxyura during their winter stay in Mexico showed the presence of the virus family Alloherpesviridae. The genus Cyprinivirus is part of this family and includes cyprinid herpesvirus 3 (CyHV3). This is the etiological agent of the lethal disease known as koi herpesvirosis, which affects different strains of Common Carp Cyrprinus carpio. In this study, samples of the contents of 87 wild duck intestines were analyzed by endpoint PCR, of which 7 samples were positive for the amplification of the TK gene fragment corresponding to CyHV3. These results contribute to the knowledge about the spread of this virus to other species of aquatic animals in areas where fish and ducks coexist.

北美迁徙野鸭首次检出锦鲤疱疹病毒（Cy HV 3）

对 Anas、Mareca、Spatula 和 Oxyura 属迁徙野鸭在墨西哥冬季逗留期间肠道内容物的病毒组学研究表明存在病毒家族异疱疹病毒科。Cyprinivirus 属是该家族的一部分，包括 Cyprinid 疱疹病毒 3 (CyHV3)。这是被称为锦鲤疱疹病毒病的致命疾病的病原体，它影响鲤鱼的不同品系。本研究对87份野鸭肠内容物样品进行终点PCR分析，其中7份样品为CyHV3对应的TK基因片段扩增阳性。这些结果有助于了解这种病毒在鱼和鸭共存地区向其他水生动物物种传播的知识。
