摘要
为了解禽白血病(avian leukemia,AL)在中国进口品种鸡群中的感染状况,2008年12月至2010年6月,在4个省市各选择1个进口品种鸡场进行禽白血病流行病学调查。此次调查共涉及4个场、5个品种、不同代次、不同生长阶段的115个鸡群共计7000余份样品,分别采集泄殖腔拭子进行p27抗原的检测和血清中的J抗体、A/B抗体的检测。结果表明,中国进口品种鸡群中存在不同程度的ALV-J亚群、ALV-A/B亚群感染,J抗体阳性率普遍高于A/B抗体阳性率,且肉鸡品种的J抗体阳性率高于蛋鸡品种;此外,本次调查结果还显示,产蛋初期的鸡群p27抗原阳性率和J抗体阳性率较高。
In order to study the infection situation of avian leukemia virus(ALV) in different import breeds in China,more than 7000 cloacal swAbs and serum samples from 4 different province were collected,then ALV-A/B,ALV-J antibody and p27 antigen were detected by ELISA.Samples collected from 4 different located poultry farms,which include 115 groups of 5 different breeds.Our investigation indicated ALV-J and ALV-A/B infection are existed in the import breeds of China generally.Moreover,the positive antibody rate of ALV-J was much higher compared to the ALV-A/B and the antibody rate of ALV-J was higher in broiler than in layer.Our investigation also showed chicken in early stage of egg production had top positive rate of p27 antigen and ALV-J antibody.
