| 摘 要： | 禽副粘病毒 2型 (PMV-2 )属于副粘病毒科、腮腺炎病毒属 ,是制备人用生物制品所用SPF鸡的必检项目。该病毒呈世界性分布 ,我国鸡群中的感染也普遍存在。 PMV-2单独感染SPF鸡仅引起轻微的呼吸道症状 ,但与 IBV、MG等禽呼吸道病病原混合感染会明显加强后者的致病作用。PMV-2的 HN基因的 ORF全长为 1 743 nt,编码一个由 580个氨基酸组成的蛋白 ,F基因较为保守 ,变异不是很大。文章重点介绍了近年来关于 PMV-2病原学、流行病学、致病性、分子生物学以及诊断和防治方法的最新研究进展。

| Abstract: | PMV 2 belongs to Paramyxoviridae and is one of test items of SPF chickens for preparing hominale biological products. PMV 2 is worldwide distribution and the infection is widespread in China. SPF chickens infected with PMV 2 showed mild symptoms of respiratory disease, but infected with PMV 2 in combination with IBV or MG showed more serious symptoms than that of PMV 2,IBV and MG respectively. We get the sequences of HN gene and F gene of PMV 2 initially in the world. Analysis of sequences revealed that each ORF of HN was composed of 1 743 nucleotides, which encoded a protein with 580 amino acids,and F genes of PMV 2 were highly conserved.This article summarized the latest progress of the etiology, epidemiology,pathogenicity, molecular biology and diagnostic methods on Avian paramyxovirus type 2(PMV 2). |
