Screening of Strains for the Bivalent Inactivated Vaccine Against Duck Infectious Serositis

    Graphical Abstract
    • Abstract
  • The comparison tests of virulence of 12 Riemerella anatipestifer strains (serotype 1and 2, 6strains for each) were carried out.The virulence of different strains were different.6more virulent strains (3strains for each) were selected to prepare inactivated oil-emulsion vaccines.6days old ducklings were vaccinated for 14 days and then challenged with the same serotype strains.The immune protective rates of the vaccine prepared by strains RAf63 and RAf34were the highest.The strains RAf63 and RAf34were proved suitable for vaccine strains.
