Correlation Analysis of Neutralizing Antibody and E2 Antibody against Classical Swine Fever Virus
In order to explore the correlation between neutralizing antibody and E2 antibody against classical swine fever virus(CSFV),289 swine sera were detected using both neutraliza-tion assay and ELISA among which neutralizing antibody titers of 15 sera were further tested by neutralization assay using different CSFV strains.The results showed that E2 antibody level a-gainst CSFV was positive correlated with neutralizing antibody titer.When the individual per-centage inhibition of E2 antibody was over 60％,the neutralizing antibody titer of more than 70％vaccinated pigs in the herd meet the protection standard.These results could help the local veteri-naries to evaluate the efficacy of CSFV vaccine better in the field and reduce the risk of CSF out-break.
