Abstract:

Avian infectious bronchitis (IB) is one of the major economically important, worldwide distributed and highly contagious and acute upper‐respiratory tract disease of poultry caused by avian infectious bronchitis virus (IBV) belonging to family Coronaviridae and affects both galliform and nongalliform birds. IBV demonstrates a wide range of tissues tropism, including the renal and reproductive systems. The clinical outcome of the infection in chickens depends on many variables such as the virus strain and type; sex and age of the chicken; immune status; co‐infections; and environmental circumstances. Effective diagnostic tools are required to diagnose IB infections in field and to identify different serotypes and variants. Diagnosis of IB is done based on the clinical history, lesions, serological investigation, virus isolations and antigen detection. Current methods, such as reverse transcription polymerase chain reaction (RT-PCR), Restriction Fragment Length Polymorphism (RFLP) and sequencing offer highly sensitive, rapid, and accurate diagnostic results within the shortest possible time. This review discusses on approaches for diagnosis of avian infectious bronchitis infection.
