Nucleotide and Amino Acid Analyses of Unique Infectious Bronchitis Virus (IBV) Variants from Canadian Poultry Flocks with Drop in Egg Production.

ABSTRACT:

Background/objectives

Infectious bronchitis (IB) is a highly infectious avian disease caused by the infectious bronchitis virus (IBV). The disease causes lesions mainly in the respiratory, reproductive, and renal systems and has a significant economic impact on the poultry industry worldwide.

Methods

We discovered two unique IBV isolates (T-62: PP737794.1 and CL-61: PP783617.1) circulating in Canada and molecularly characterized them.

Results

The phylogenetic analysis revealed that the IBV isolates belong to genotype I and fall between lineages 25 and 7. Further analysis of the T-62 IBV isolate indicated that it is a potential recombinant of the Iowa state isolate (IA1162/2020-MW) and that the CL-61 strain of the IBV is also a recombinant IBV with the Connecticut (Con
