VILLARREAL, LYB. Diagnosis of infectious bronchitis: an overview of concepts and tools. Rev. Bras. Cienc. Avic. [online]. 2010, vol.12, n.2, pp.111-114. ISSN 1516-635X.

Infectious bronchitis (IB) casues multi-systemic infection in chickens with signs similar caused by other poultry pathogens and thus a high diagnostic accuracy can only be achieved by s series of laboratory assays. This article reviews in a brief way the traditional virus assays such as embryo innoculation, tracheal rings and virus neutralization assays for the direct detection of Avian infectious bronchitis virus (IBV) and methods based on gene molecular biology and some assays for the detection of anti-IBV antibodies, including ELISA. A critical view on each technique is also provived by the author.
