摘要
为掌握信阳地区土鸡A-B亚群禽白血病流行情况,于2016年3月—2017年7月,采用ELISA方法对采自信阳地区77个土鸡场的1 351份血清样品进行检测。结果显示,A-B亚群禽白血病阳性鸡场26个,鸡场阳性率为33.8%,阳性样品75份,个体阳性率为5.6%;不同月份阳性率有差异,1月鸡场阳性率最高,为66.7%,10月未检出阳性样品,4月个体阳性率最高,为33.3%;不同规模养殖场阳性率差异不大,规模鸡场阳性率为38.5%、个体阳性率为5.5%,散养户鸡场阳性率为28.9%、个体阳性率为5.6%。可见,禽白血病在信阳地区已经普遍存在,今后要加强对该病的净化及根除工作,有效控制其蔓延。
To know the epidemic situation of avian leukosis subgroup A-B in Xinyang area,the ELISA method was adopted to test 1 351 serum samples,which were obtained from 77 local chicken farms during March 2016 to July 2017. The results showed that 26 farms were positive,the farm positive rate being33. 8%,and 75 samples were positive,the sample positive rate being 5. 6%. The positive rates varied very much in different months,such as 66. 7% of farm positive rate in January,no positive samples in October.The sample positive rate was the highest in April（33. 3%）. Besides,the farm positive rates and sample positive rates were not significantly varied in different farms,38. 5% and 5. 5% in scale farms,28. 9%and 5. 6% in free-range households respectively. The results demonstrate that avian leucosis is already ubiquitous in Xinyang,and efforts must be taken to purify and eradicate this disease,so as to bring it under control.
