混合感染猪繁殖与呼吸综合征和圆环病毒2型猪群的猪瘟抗体变化研究
Study on the Changes of Antibody to Classical Swine Fever in the Swine Herds Co-infected with PRRSV and PCV-2
摘要
Abstract
To analyze and detect the antibody to CSFV in the swine herds co-infected with PRRSV and PCV-2. RT-PCR,real-time fluorescence RT-PCR and PCR methods were used to detect the highly pathogenic PRRSV,CSFV and PCV-2 in the deseased swine farm of Sichuan. The results showed that the positive rates of highly pathogenic PRRSV, PCV-2 and CSFV were 54%(19/35),50%(17/34)and 0(0/5) respectively. Combined with clinical symptoms and au-topsy change,the diagnosis results were co-infection with PRRSV and PCV -2. CSFV antibody was detected by ELISA in the 12 serum samples of experimental group of pigs co-infected with PRRSV and PCV-2 and in the 12 serum samples of control group of healthy pigs(no clinical symptoms,negative antigen detection). The results showed that CSFV anti-body qualified rate was 33%(4/12)in the infected pigs group,significantly lower than that of the healthy control group with the qualified rate of 83.3%(10/12)((P < 0.05).It was indicated that there was negative effect on CSFV antibody production with mixed infection of PRRSV and PCV-2.关键词
