Abstract: Infectious bronchitis (IB) is an acute and susceptible infectious disease,which has been classified as B loemia and causes a grave threat to the poultry industry.Now,the primary prevention measures of IB are vaccine inoculation.With the diversity of infectious bronchitis virus (IBV) serotype and easy variation,and the weakness of cross protection,the prevention and control of IB were a major problem in poultry industry.In this ariticle,it summarized the molecular biological characteristics, and the development and immunization strategy of the attenuated vaccine of IB to provide scientific references for the research and application of IB attenuated vaccine.

Key words: infectious bronchitis virus; S protein; M protein; N protein; attenuated vaccine
