福州市鸡群网状内皮增生症病毒血清学调查与初步分析

Serological investigation and preliminary analysis on Reticuloendotheliosis Virus in chicken flocks in Fuzhou

应用ELISA抗体检测试剂盒,对福州市9个养殖场鸡群进行网状内皮增生症病毒（Reticuloendotheliosis Virus,REV）抗体检测。共采集了鸡血清样品427份。结果表明,被检样品总的阳性率为29.51%（126/427）,阳性的鸡场数占鸡场总数的77.78%（7/9）,养殖场个体阳性率在0~98.36%之间。经比较不同品种REV抗体阳性率,发现肉鸡的感染率最高（61.18%）,蛋鸡次之（15.48%）,种鸡最低（6.60%）。不同日龄段不同品种的鸡群REV抗体阳性率呈散在分布。

The antibody of the reticuloendotheliosis virus（REV） was found in 9 flocks of chicken in Fuzhou using a commercial ELISA REV antibody test kit.Four hundred twenty seven serum samples were collected.The results indicated that the positive rate on the tested serum samples was 29.51%（126/427）.The antibody could be detected in 7 of the 9 flocks（77.78%）.The percentage of positive sera per flock ranged between 0 and 98.36%.Comparison of the positive rates of antibody against REV of different chicken varieties showed the positive antibody rates were highest in broilers（61.18%）,with layers second at 15.48%,followed by breeders at 6.60%.There appeared to be no significant correlationship between the positive rate and age or variety of the chickens.In other words,the REV infection was prevalent among chicken flocks in Fuzhou,with a varying degree of susceptibility for chickens of different age or variety.
