Abstract: The antibodies in sera from chickens vaccinated with bivalent vaccine of Infectious Coryza were measured by B ELISA,HI and SPA,and the antibody curves were also protracted.The results showed that the B ELISA antibody to serovar A and HI antibodies remained a high level post vaccination;the C serovar B ELISA antibody and SPA antibodies reached their vertex at 50-180 days and 50-60 days,respectively,and after that the level of the antibodies decreased slowly.All the antibodies could be detected more than 390 days post vaccination.These results also demonstrated the good sensitivity of the B ELISA and SPA,and gave a reference for the further application of the bivalent vaccine,all the diagnostic methods and correlative products.

Key words: Blocking ELISA, HI, SPA, Bivalent Inactivated Oil Adjuvant Vaccine to Infectious Coryza, Antibody curve
