| 摘 要： | 传染性法氏囊病(Infectious bursal disease,IBD)是由传染性法氏囊病病毒(Infectious bursal disease virus,IBDV)引起的一种急性、高度接触性传染病.20世纪80年代中期以后,由于抗原变异和超强毒株在免疫鸡群的出现,使IBD的防控面临新的困难.文章简要概述近几年来,IBD在病原及分子生物学特性、抗原性、致病性、毒力与抗原的变异、疾病诊断和防制策略等方面的研究进展.

| Abstract: | Infectious bursal disease(IBD),caused by infectious bursal disease virus(IBDV),is a highly contagious and acute viral disease affecting young chickens.The emergence of antigenic variant as well as very virulent strains in vaccinated flocks considerably makes a new problem to the prevention of the disease.In this review,some of the recent advances in the understanding of the etiological agent and its molecular biology,antigenicity,pathogenicity,variations of virulence and antigen,diagnosis and new strategies for prevention of the disease were briefly summarized. |
