摘要
用酶联免疫吸附试验(ELISA)方法,对2005年-2008年采自青海农区的5 514份猪血清中猪繁殖与呼吸综合征病毒(PRRSV)抗体进行了检测。结果表明,PRRS血清抗体在被调查的37个养猪场中,PRRS阳性猪场28个,占75.7%。检测后备母猪血样207份,阳性率23.7%;妊娠母猪血样467份,阳性率29.1%;空怀母猪血样209份,阳性率35.9%;哺乳仔猪血样1 128份,阳性率20.6%;断奶仔猪血样1 588份,阳性率3.84%;肥育猪血样1 915份,阳性率3.6%。另外,养猪场猪群的PRRS血清抗体阳性率14.1%,市售生猪、农户散养猪的血清抗体阳性率分别为5.1%和10.6%。
A seral epidemiological investigation on porcine reproductive and respiratory syndoromce（PRRS） were carried out by ELISA in the agricultural areas of Qinghai province. 5 514 sera were collected in recent four years （from 2005 to 2008）. The PRRSV serum antibodies were determined with ELISA. The total positive rate of PRRSV serum antibody was 11.28%. 28 PRRSV positive pig farms were found from 37 in- vestigated pig-farms,positive rate was 75.7%. Serum samples in gilt were 207, the positive rate was 23. 7 ;. Serum samples in pregnant sow were 467,the positive rate was 29.1%. Serum samples of unpregnant sow were 209,the positive rate was 35.9;. Serum samples in suckling piglets were 1 128,the positive rate was 20.6%. Serum samples in weaning piglets were 1 588,the positive rate was 3.84%. Serum samples in fattening pigs were 1 915, the positive rate was 3.6 %. In addition, the positive rate of serum-antibody in pig farms was 14.1%, meanwhile the positive rate of serum-antibody in market pigs was 5.1%,the positive rate of serum-antibody of peasant household pigs was 10.6%. The results provided the foundation for preventing and controlling PRRS in the future.
