摘要: 采用ELISA方法对京郊某种鸡场2群鸡从出雏到4周龄进行禽白血病病毒p27(ALV-p27)抗原检测,对血清进行ALV-AB及ALV-J抗体检测,按标准计算方法对检测数据进行分析.结果表明:A群鸡不同周龄直肠拭子中ALV-p27抗原检出率差异显著,出雏时为0.73%(2/273),8周龄最高,阳性率达4.06%(114/23);B群鸡不同周龄直肠拭子中ALV-p27抗原检出率差异显著,出雏时为0(0/182),14周龄时最高,达4.2%(66/14).A群鸡38,4周龄ALV-J抗体阳性率分别为3.71%(1/42),27.08%(13/48),B群鸡27,34,43周龄ALV-J抗体阳性率分别为4.00%(2/0),2.33%(1/43),9.30%(4/43).A群鸡4周龄ALV-AB抗体阳性率为8.33%(4/48),B群鸡34,43周龄ALV-AB抗体阳性率分别为6.98%(3/43),6.98%(3/43).同时建立PCR检测ALV的方法,分别扩增出大小为717 bp P27抗原片段和4 bp的ALV-J特异性片段,P27片段与ALV-J亚群毒株HPRS-103、NX0101的相应核苷酸序列同源性达91.3%和94.7%,ALV-J特异性片段与ALV-J亚群毒株HPRS-103、NX0101的相应核苷酸序列同源性达97.1%~97.3%和98.1%~98.6%.

Abstract: ELISA was used to detect the P27 antigen of avian leukosis virus (ALV-P27) in fecal swabs of two flocks in one chicken breeder farm in Beijing suburb,a nd serum samples of corresponding flock were collected for detection antibody of ALV-J and ALV-AB. The results showed that the detection rate of ALV-P27 was significant difference in flock A. The detection rate of ALV-P27 was respectively 0. 73% (2 /273) at 0 day, 45. 06% (114 /253) at 8 weeks,and the rate of ALV-P27 was 0(0 /182) at 0 day and 45. 52% (66 /145) at 14 weeks in flock B. The detection rate of antibody of ALV-J was 35. 71% (15 /42) ,27. 08% (13 /48) in flock A and 4. 00% (2 /50) ,2. 33% (1 /43) , 9. 30% (4 /43) in flock B. The detection rate of antibody of ALV-AB was 8. 33% (4 /48) in flock A and 6. 98% (3 /43) 、6. 98% (3 /43) in flock B. Simultaneously,a mplified by PCR and sequenced. The specific fragment of 717 bp for P27 and 545bp for ALV-J was amplified from samples. The amplified 717 bp fragment shared 91. 3% and 94. 7% identities in nucleotide with that of HPRS-103 and NX0101 strains of ALV-J. And 545 bp fragment shared 97. 1%-97. 3% and 98. 1% -98. 6% identities in nucleotide with HPRS-103 and NX0101 strains of ALV-J.
