摘要: 为探索2011年年底在广东阳江地区某肉鸭场出现的病鸭和死鸭的发病原因,对其中2个发病鸭场的病死鸭进行了解剖,对病变组织的样品应用RT-PCR的方法进行了病原鉴定。经剖检,发现鸭心脏表面形成小结节,伴有少量心包积液;肝脏和胆囊肿大;脾脏有花斑;胰腺和直肠有出血点。利用病料研磨上清和病料接种后的鸡胚尿囊液进行RT-PCR检测,结果显示鸭黄病毒阳性。序列分析显示,该病毒的核苷酸序列与坦布苏病毒Fengxian株的相似性为99%。试验结果表明,该病毒为黄病毒,是引起此次鸭场发病的病原。

Abstract: At the end of 2011, a new duck infectious disease emerged in Guangdong province. In order to identify the etiological agent, the pathological examination and RT-PCR were carried out. By autopsy, we found that cardiac sarcoidosis, accompanied with a few pericardial effusion; liver and gallbladder swelled; spleen was slightly mottled; pancreas and rectum with hemorrhagic spots. The samples from affected ducks and the allantoic fluid of affected chick embryos, were detected positive by duck flavivirus RT-PCR method. Sequence analysis showed that the isolated virus shared 99% nucleotide identity with duck flavivirus Fengxian strain. These results suggested that the isolated virus belonged to duck flavivirus and was the reason for the infectious disease of duck.

Key words: duck flavivirus; RT-PCR; sequence analysis
