中文摘要：
2013年湖北某大型养鸭场饲养的肉种鸭出现了一定程度的产蛋下降．送检的病鸭都有不同程度的眼睑肿大，对发病鸭进行了病理剖检及病毒的PCR鉴定，其中PCR检测鸭瘟为阳性。对PCR扩增的鸭瘟病毒目的片断进行回收测序，测序结果进行序列比对，表明该目的片断与已发表的鸭瘟病毒UL31基因序列的同源性较高为99％，具有较近的遗传进化关系。
英文摘要：
In 2013, the ducks at a farm in Hubei province were observed with sudden drop of egg. The ill ducks all had different levels of swelling at blepharon. Through pathological anatomy and PCR detection, the samples were found to be positive to duck plague virus but negative to avian influenza virus, Newcastle disease virus and egg-drop syndrome virus. The sequence analyses based on amplifying duck enteritis virus gene revealed that the strain was most closely related with the published sequence of duck enteritis virus UL31 gene, with the nucleotide indentity of 99%.
