Abstract: Infectious coryza (IC) of chickens, a severe upper respiratory infectious disease, is caused by the infection of Avibacterium paragallinarum. With the changes of breeding environment, there are increasing difficulties in prevention and control of IC. Vaccination has become one of the most commonly used ways for IC prevention. The existing inactivated IC vaccines have the advantages of convenient employment, but also have the disadvantages of severe stress and deficient efficacy. Several commonly used vaccines, future vaccine development and preventive strategies of IC were summarized in this paper, in hoping to provide theoretical guidance for better prevention and control of this disease.

Key words: chicken infectious coryza, prevention and control, vaccine, research progress
