2010年4月我国出现了一种新发疾病,该疾病可导致鸭产蛋量下降、采食量减少,后来确定该病是由鸭坦布苏病毒(Duck Tembusu Vieus,DTMUV)引起的一种主要感染鸭的传染病,该病发病急、传播快,死淘率高。该病首先在浙江等沿海地区出现,之后迅速蔓延至养鸭比较密集的其余省份,并逐步蔓延至内地,如福建、广东、广西、安徽、江西、江苏、河南、河北、山东和北京等地。该病主要感染鸭,产蛋鸭感染后产蛋率将大幅度下降,从90%降至10%,更为严重的甚至导致绝产;雏鸭感染后通常表现为神经症状,并伴有较高的死亡率,对养鸭业的发展有着巨大的威胁。本研究调研鸭坦布苏病毒病的病原学、流行病学、诊断方法以及防控措施等方面,总结鸭坦布苏病毒病的易感动物、鸭群不同年龄段的发病率、临床症状和病理变化、不同预防方案和治疗方案之间的对比分析,从而为鸭坦布苏病毒病的诊断与防控提供参考和指导。

ABSTRACT
From April 2010, a new disease occurred in China that caused a drop in duck egg production and reduced feed intake. It was later determined that the disease was a major cause of Duck Tembusu Vieus (DTMUV) Infectious disease infected with ducks. The disease has an acute onset, spreads quickly, and a high rate of death. The disease first appeared in Zhejiang, and then quickly spread to Fujian, Guangdong, Guangxi, Anhui, Jiangxi, Jiangsu, Henan, Hebei, Shandong, and Beijing, where duck farming is relatively dense. The disease mainly infects ducks, and the laying rate of laying ducks will be greatly reduced after infection, from 90% to 10%, which is even more serious and even leads to childbirth. Ducklings usually show neurological symptoms after infection and are accompanied by The high mortality rate poses a huge threat to the development of the duck industry. Therefore, this article briefly describes the etiology, epidemiology, diagnostic methods, and prevention and control measures of duck tambusu virus disease, and summarizes the susceptibility of duck tambusu virus disease, the incidence and clinical symptoms of different age groups of ducks And pathological changes, comparative analysis of different prevention and treatment programs, so as to provide reference and guidance for the diagnosis and prevention of duck tambushu virus disease.
