摘要

摘要: 为了调查蛋鸭禽1型副黏病毒的感染状况,以RT-PCR技术对2011年以来采自福建、浙江、江西、广东、广西和江苏六省(区)的495份蛋鸭样品进行了禽1型副黏病毒的检测,并测定了部分禽1型副黏病毒分离株对不同日龄麻鸭的致病性。结果表明六省(区)份蛋鸭的禽1型副黏病毒的阳性感染率高低不一,为3.4%~10.7%,揭示了禽1型副黏病毒在我国蛋鸭中存在不同程度的感染;禽1型副黏病毒感染可致死低日龄麻鸭,其中基因VII型鸭源分离株对麻鸭的致死率高于基因IX型,且随着麻鸭日龄的增长其致死率降低,即呈现日龄易感性差异,开产麻鸭感染禽1型副黏病毒则表现为产蛋率显著下降。

Abstract: To investigate the epidemiology of Avian Paramyxovirus type 1(APMV-1) in laying ducks, a total of 495 samples were collected from laying ducks in six provinces (Fujian, Zhejiang, Jiangxi, Guangdong, Guangxi and Jiangsu) during 2011-2015. All samples were tested by using reverse transcript PCR to detect APMV-1 infection, and pathogenicity of different virus isolates were determined in laying ducks. Results showed that positive rate of APMV-1 in laying duck was range from 3.4% to 10.7%, and this indicated that APMV-1 was circulated in ducks in different place unevenly. Pathogenicity analysis showed that lethality rate in Sheldrake infected with genotype VII APMV-1 was higher than that in Sheldrake infected with genotype IX APMV-1. The pathogenicity of APMV-1 in laying duck was decreased according to the increase in age, while the laying performance of the older Sheldrake was heavy affected under the infection of APMV-1.
