猪圆环病毒2型感染对猪瘟疫苗免疫效果的影响
Influence of Porcine Circovirus Type 2 Infection on Immune Effect of Classical Swine Fever Vaccine
摘要
Abstract
In order to explore the influence of Porcine Circovirus Type 2 (PCV -2 )vaccination on the immune effect of Classical Swine Fever (CSF)vaccine in the PCV -2 positive pig farms during practical clini-cal production,150 piglets in a farrowing house of a large pig farm which had been confirmed to be PCV -2 positive were randomly divided into two groups,namely,test group and contrast group,and each 75 piglets. The piglets in the test group were immunized with the imported PCV -2 baculovirus vector inactivated vaccine when they were 14 days old.Then,18 piglets were randomly selected from each group before PCV -2 vacci-nation and 30 days after CSF revaccination respectively.The detection results showed that:there was no difference between the two groups in CSF antibody level before PCV -2 vaccination;30 days after CSF revac-cination,the average value and dispersion of CSF antibody in the test group were significantly higher than those of the contrast group.It indicated that the immune system of pigs could be damaged by PCV -2 infection and the immune response of CSF vaccine was suppressed.In addition,the immune effect of CSF vaccine could be enhanced by immunizing with PCV -2 vaccine in the PCV -2 positive pig farms.关键词
