传染性支气管炎病毒(IBV)变异株不断出现,并对世界各地的家禽养殖场构成经济威胁。2007至2017年间,人们对IBV变异株的分子和病原学特征进行了大量研究,我们在此进行了综述。我们注意到,病毒基因突变和重组事件通常会导致不同的IBV基因型、血清型和病毒型。除了确定S1基因的特征外,对新出现的变异株的全病毒基因组测序、全面的抗原性和致病性研究也促进了我们对IBV感染的理解,这对于制定应对IBV现场暴发的对策具有重要价值。本文对IBV变异株的综述为从地区和世界范围内了解它们的系统发育关系和流行病学提供了实用价值。
Infectious bronchitis virus (IBV) variants constantly emerge and pose economic threats to poultry farms worldwide. Numerous studies on the molecular and pathogenic characterization of IBV variants have been performed between 2007 and 2017, which we have reviewed herein. We noted that viral genetic mutations and recombination events commonly gave rise to distinct IBV genotypes, serotypes and pathotypes. In addition to characterizing the S1 genes, full viral genomic sequencing, comprehensive antigenicity, and pathogenicity studies on emerging variants have advanced our understanding of IBV infections, which is valuable for developing countermeasures against IBV field outbreaks. This review of IBV variants provides practical value for understanding their phylogenetic relationships and epidemiology from both regional and worldwide viewpoints.
