Efficacy of Commercial Infectious Bronchitis Vaccines against Canadian Delmarva (DMV/1639) Infectious Bronchitis Virus Infection in Layers

Vaccines, 2022
Vaccination is the most important way to control infectious bronchitis (IB) in chickens. Since the end of 2015, the Delmarva (DMV)/1639 strain of infectious bronchitis virus (IBV) has caused significant damage to the layer flocks in Eastern Canada.

Molecular Epidemiology of Infectious Bronchitis Virus in The Netherlands

Journal of General Virology, 1987
Twelve Dutch isolates and the M41 strain of infectious bronchitis virus (IBV), a coronavirus of chickens, were characterized by cross-neutralization and T1 finger-printing to elucidate their evolutionary relationship. The T1 fingerprinting showed that the Dutch isolates formed two clusters.

Genotyping of infectious bronchitis virus in Canada

Journal of Veterinary Diagnostic Investigation
From 2014–2023, infectious bronchitis virus (IBV) was detected in 6,589 samples from Canada, and partial nucleotide (nt) sequences of the IBV spike protein ( S) gene were determined for 1,678 samples. Based on their S gene nt sequence identities and origin, Canadian IBVs could be classified into 4 groups: 1) 50.3% were variant viruses related to ...
