摘要: 进行猪繁殖与呼吸综合征(PRRS)疫苗安全及效力试验时,需要选用猪繁殖与呼吸综合征病毒(PRRSV)抗原、抗体均为阴性的猪血清。为此,应用EUSA和RT—PCR方法对取自陕西省关中部分县(区)散养的未进行猪繁殖与呼吸综合征疫苗免疫猪群共计135份血清样品进行了PRRSV抗体和抗原测定。结果表明,PRRSV抗体阳性率为6.67%(9/135).PRRSV抗体阴性猪群中抗原阳性率为11.11%(14/126)。由此可以得出,该地区农户散养的猪群存在感染猪繁殖与呼吸综合征病毒的危险。

Abstract: During the detection on safety and effectiveness of porcine reproductive and respiratory syndrome (PRRS) vaccine, pigs which antigen and antibodies of PRRS negative were needed. In this experiment, 135 pig serum samples which came from five counties (districts) of Guanzhong Area, Shaanxi Province were tested by ELISA and RT-PCR method. The results showed that antibody-positive rate and antigen positive rate of PRRS were 6.67% (9/135) and ll.ll% (14/126) respectively. It proved that the presentments and control of PRRS in scatter-feed herds were insufficient, there is great danger of PRRSV infection.
