Avian infectious bronchitis virus (IBV) is a coronavirus which infects chicken, causing the associated disease, infectious bronchitis (IB. It is a highly infectious avian pathogen which affects the respiratory tract, gut, kidney and reproductive systems of chickens.
IBV is a coronavirus, recently relocated to genus Gammacoronavirus , with a non-segmented, positive-sense single-stranded RNA genome.
When inhaled, virus will attach to glycoprotein receptors containing sialic acid on ciliated epithelial cells of the respiratory epithelium. The respiratory replication will result in loss of ciliary activity , mucus acumulation, necrosis and desquamation, causing respiratory distress, râles and asphyxia. Local virus replication will result in viremia, spreading the infection into other tissues and organs. Other respiratory diseases of chickens (Mycoplasma gallisepticum, avian infectious laryngotracheitisGallid herpesvirus 1, Newcastle disease, Avian metapneumovirus infection may be...
