Sixty field strains of avian infectious bronchitis virus (IBV) were isolated from chicken flocks in different regions of Guangxi from 1985 to 2012. Phylogenetic analysis of S1 subunit glycoprotein genes revealed that field isolates from 2009-2011 mostly belonged to the LX4 type, while those from 1985-2008 belonged to the HN08 type, and a few others belonged to the 4/91 type, the TW type and the Mass type. In addition, it is noteworthy that no obvious regional differences were found among these 60 strains isolated from six regions in Guangxi, while there was a high degree of sequence identity among the isolates in the same period of time.
从 1985 年到 2012 年，从广西不同地区的鸡群中分离到 60 株禽传染性支气管炎病毒（IBV）野毒株。S1 亚单位糖蛋白基因的系统进化分析表明，2009-2011 年分离的野毒株主要属于 LX4 型，而 1985-2008 年分离的野毒株属于 HN08 型，少数属于 4/91 型、TW 型和 Mass 型。此外，值得注意的是，从广西六个地区分离到的这 60 株病毒之间没有明显的地域差异，而同一时期分离到的病毒株之间具有高度的序列同一性。
