[Meth- od] The type 1 pilus was respectively isolated from the recombinant bacteria CZYR10 strain and wild avian Eschedchia co/i YR（ O18 ） strain and used to prepare oil-emulsified vaccine. The immunogenicity of the developed vaccine was detected in chickens using the challenge test. [ Result] The recombinant type 1 pilus protein had immunoprotective efficacy. The recombinant type 1 pilus protein had weaker protective efficacy than the isolated type 1 pilus protein, but the difference was not significant. [ Conclusion] The study provides a reference for immunization and control of chicken colibacillosis.展开更多
