摘　　要：鸡传染性支气管炎(Infectious bronchitis,IB)是由鸡传染性支气管病毒(IBV)引起鸡的重要的传染病,可对养禽业造成巨大经济损失。为了解攀西地区IB流行情况,采用鸡胚接种、RT-PCR以及测序法对该地区采集的病料样品831份进行检测,结果表明,2013年-2015年四川攀西地区IBV总检出率为15.16%,其中每年检出率分别12.35%、13.23%和20.83%;4周龄~6周龄、17周龄~21周龄的蛋鸡与3周龄~5周龄肉鸡IBV感染率较高,该阶段为感染高峰期;IBV感染在本地区有比较明显的季节性,每年11月份至次年4月份是感染高峰期。研究结果可为攀西地区科学防控鸡传染支气管炎提供参考资料。Avian infectious bronchitis （IB） is an important infectious disease caused by avian infectious bronchitis virus （IBV）. IB has caused some serious economic losses in poultry industry. In order to know about the epidemiological situation of IB in Panxi area, 831 samples collected in this area were detected by the methods of embryo inoculation, RT-PCR and sequencing method. The results showed that 15.16% of all samples were infected with IBV and the overall positive rates in the year of 2013, 2014 and 2015 were 12.35%, 13.23%, 20.83%, respectively. IBV infection had obvious seasonal characteristics in the local area, and the peak infection started in November and lasted until April next year. Both the layer chicken at the age of 4-6 weeks and 17-21 weeks and broilers at the age of 3-Sweeks had the higher infection rate. This study provided the scientific strategies for prevention and controlling IB.
