A simple objective method to quantify embryo dwarfism induced by infectious bronchitis virus in embryonated chicken eggs has been used to determine endpoints in virus titration and neutralization assays. The eggs and the respective embryos were weighed and embryo:egg weight (EE) ratios were calculated. The EE ratios were compared with the uninoculated control eggs and endpoints could be calcula...
Background: Avian infectious bronchitis (IB), with avianinfectious bronchitis virus (IBV) as the causing agent, is a ubiquitous endemicdisease of the chicken with devastating effects on its industry. A viralmembrane surface protein called S notonly induces neutralizing antibodies but also plays an important role in virusbinding and entry to host cells. Technically, S1 protein gene sequencing a...
