Infectious bronchitis is widely distributed in the major poultry raising areas in California. However, all respiratory diseases of poultry are not caused by infectious bronchitis virus. Vaccination with a live virus vaccine against an impending respiratory disease should not be attempted until the respiratory condition for which the vaccine is intended has been correctly diagnosed by a qualified veterinarian or laboratory.
