鸭产蛋下降-死亡综合征的临床诊断与病原的初步鉴定
Clinical diagnosis and pathogenic identification of egg drop-death syndrome in duck
摘要
Abstract
During March to November of 2010, a kind of duck disease, which was characterized by egg drop and death syndrome, occurred in large-scale duck farms in Anhui province. A strain of flavivirus was isolated by chicken embryo inoculation and RT-PCR from the infected ducks, which experienced the gross lesions with myocardial hemorrhage, ovari-an enlargement and necrosis. Animal regression experiment was conducted for identification of pathogenicity of virus iso-late. The results suggested that this disease was caused by a new duck flavivirus that was closely related to Tembusu virus, which shared 94. 2% sequence homology at NS1 nucleotide level. This study further confirmed that duck flavivirus was highly pathogenic to duck in China and began to spread in large scale duck farms, and it is necessary to attach great importance to duck flavivirus infection.关键词
