摘要
[目的]测试sFat-1转基因猪的遗传稳定性,以及对7种疾病的易感性差别。[方法]采用PCR法检测传代仔猪sFat-1基因整合情况,并用ELISA和PCR法检测转基因猪对伪狂犬病、钩端螺旋体病、猪密螺旋体痢疾、布鲁氏菌病、轮状病毒、结核杆菌病和猪支原体肺炎的感染情况。[结果]sFat-1转基因猪F3代仔猪阳性比例为18.5%,转基因阳性猪和阴性猪对7种疾病的易感性没有明显差别。[结论]sFat-1转基因猪外源基因遗传不稳定,转基因阳性和阴性猪体质整体情况接近。
[Objective] This study aimed to investigate the hereditary stability of sFat-1 transgenic pigs and the differences in disease susceptivity between sFat-1 transgenic pigs and non-transgenic pigs. [Method] The integration of sFat-1 gene in pigs was detected by PCR; the infection of transgenic pig to pseudorabies, leptospirosis, swine dysentery, brucellosis, Mycobacterium tuberculosis, rotavirus and mycoplasma hyopneumoniae was detected by using ELISA and PCR. [Result] The positive ratio of F3 generation sFat-1 transgenic pigs was 18.5%; the susceptivity of positive sFat- 1 transgenic and negative pigs to seven infectious diseases showed no significant difference. [Conclusion] Exogenous gene in sFat-1 transgenic pigs can not be stably inherited. The overall physical condition of positive transgenic and negative pigs was similar.
