Infectious bronchitis (IB) is a poultry viral disease caused by a coronavirus,
an enveloped RNA virus. The coronavirus belongs to the Coronaviridae
family. The essential coronavirus characteristic is antigenic
plasticity, because of the variable amino acid sequences of spicules on
the surface.

In hens, IB can cause thin-walled eggs, loss of shell pigmentation, and cessation of egg-laying

IB primarily causes respiratory disease, but can also affect the kidneys, gut, and reproductive systems. Signs include coughing, nasal discharge, conjunctivitis, and respiratory distress. In hens, IB can cause thin-walled eggs, loss of shell pigmentation, and cessation of egg-laying.
