Abstract
Infectious bronchitis virus (IBV) is an economically significant problem for the commercial egg industry globally despite the widespread use of live and inactivated vaccines. The presence of multiple serotypes and the rapid evolution of this virus complicate prevention of the disease by vaccination. This virus is able to multiply in the epithelia of a range of tissues in the body, usually commencing in the respiratory system. It can also multiply in the Harderian gland, kidney, gastrointestinal tract, and oviduct. Many serotypes cause drops in egg production accompanied by reduced shell quality and albumen quality. Loss of shell color in brown egg layers is a very common effect of IBV although it may also cause the production of thin shelled, misshapen, and corrugated eggs as well as more elongated eggs. The IBV produces pathological effects on body tissues including the oviduct, which can be clearly identified by light and electron microscopy.
