Avian infectious bronchitis virus.

Infectious bronchitis virus (IBV) is prevalent in all countries with an intensive poultry industry, with the incidence of infection approaching 100% in most locations. Vaccination is only partially successful due to the continual emergence of antigenic variants. At many sites, multiple antigenic types are simultaneously present, requiring the application of multiple vaccines. Although many coun...

Detection of infectious bronchitis virus.

The detection methods for infectious bronchitis virus (IBV) are reviewed. Advantages and disadvantages of available techniques of IBV detection by virus isolation, antigen or genome detection, and serology are discussed. Factors of influence on the level of success in detection of IBV after a disease outbreak are discussed, as are the possibilities and dangers of strain classification by protec...

Coronavirus avian infectious bronchitis virus.

Infectious bronchitis virus (IBV), the coronavirus of the chicken (Gallus gallus), is one of the foremost causes of economic loss within the poultry industry, affecting the performance of both meat-type and egg-laying birds. The virus replicates not only in the epithelium of upper and lower respiratory tract tissues, but also in many tissues along the alimentary tract and elsewhere e.g. kidney,...
