| 摘 要： | 本研究首次通过检测种蛋中禽白血病病毒(ALV)评价了皖南黄父母代肉种鸡的ALV感染状态.收集该鸡群的120枚鸡蛋,取40枚鸡蛋孵化至9～11 d后分别制备CEF,培养10 d,取细胞上清用ELISA试剂盒检测ALV p27抗原.另取80枚鸡蛋卵白直接检测p27抗原,同时分别将80枚鸡蛋卵白接种CEF(DF1),培养10 d后取细胞上清检测p27抗原.比较p27阳性检出率的结果表明,受精蛋孵化9～11 d后制备CEF,再培养10 d的细胞上清检出率(10/36)高于直接检测卵白(17/80)与卵白接种CEF(DF1)的细胞上清(7/80).将经DF1培养后p27抗原阳性样品,用针对ALV-J的单抗JE9做IFA,ALV-J的阳性率为6/7.检测该80枚鸡蛋的卵黄抗体,ALV-J、ALV-AB的抗体阳性率分别为18/80、1/80.结果表明,该皖南黄父母代肉种鸡群存在的外源性ALV感染主要为ALV-J.该研究为ALV的净化提供了可行性检测方法. |

| Abstract: | In the present study,the infection of avian leukosis virus(ALV) in parent breeder flock was evaluated by the inspection of fertilized eggs.120 eggs were obtained for a flock of Wan-nan yellow-feather parent layers.40 eggs were hatching for 9 to 11 days for the preparation of CEF,which were cultured for 10 days and the supernatants were collected for the measurement of p27 antigen by ELISA.The egg white was obtained from the other 80 eggs and used for the direct measurement of p27 antigen or indirect measure... |
