摘要
为了解甘肃省天水市鸡禽白血病的流行情况,本文采用实时荧光PCR方法对2020~2021年采集的24个规模鸡场的480份泄殖腔拭子进行了病原学检测。结果显示,24个规模场中阳性场18个,场点阳性率为73.33%;480份样品中阳性样品203份,样品阳性率42.29%。其中不同用途的鸡禽白血病感染率不同,360份蛋鸡样品中阳性138份,阳性率38.33%;120份肉鸡样品中阳性65份,阳性率54.17%。结果表明,禽白血病病毒在天水市规模鸡场存在普遍流行的现象,且肉鸡的感染率高于蛋鸡。
In order to understand the prevalence of Avian Leucosis in Tianshui City,Gansu Province,this paper used real-time fluorescent PCR method to carry out pathogenic detection on 480 cloacal swabs collected from 24 large-scale chicken farms from 2020 to 2021.The results showed that 18 of the 24 scale farms were positive,with a positive rate of 73.33%.Among the 480 samples,203 were positive,and the positive rate of the samples was 42.29%.Among them,the infection rate of Avian Leucosis for different purposes is different.Among the 360 laying hen samples,138 were positive,and the positive rate was 38.33%.Among the 120 broiler samples,65 were positive,with a positive rate of 54.17%.The results showed that Avian Leucosis virus was prevalent in large-scale chicken farms in Tianshui City,and the infection rate of broiler chickens was higher than that of laying hens.
