对猪使用基因编辑技术 有迹象表明猪对主要病毒性疾病产生抗性

　　UK - Scientists have produced pigs that may be protected from an infection that costs the swine industry billions each year.The team have used advanced genetic techniques to produce pigs that are potentially resilient to Porcine Reproductive and Respiratory Syndrome (PRRS).Early tests have revealed that cells from the pigs are completely resistant to infection with both major subtypes of the virus that causes the disease.The animals are otherwise healthy and the change – introduced using gene-editing technology – should not affect their ability to fight off other infections, the researchers say.

　　英国科学家培育出一群可能抵御感染的猪，这种感染每年让养猪业损失数十亿。由于科学团队采用了先进的基因技术，这些猪有可能适应猪繁殖与呼吸综合征(PRRS)。早期测试表明，猪细胞能完全抵抗猪繁殖与呼吸综合征的病毒感染。研究人员称，测试猪原本都处于健康状态，此后对它们实施基因编辑技术，应该不会影响到猪对其他感染的抵抗力。
