Chickens.
The infectious bronchitis virus (IBV) is the cause of avian infectious bronchitis (IB), which is one of the most highly contagious diseases, resulting in many economic losses in the poultry industry worldwide.1
One emerging genotype of epidemiological importance is the GI-23 lineage (EGY VAR II-like strains) which has shown a widespread prevalence beyond the Middle East, with recent detections reported in Asia, Europe, and Africa. This spread, illustrates the ability of the GI-23 lineage to extend its geographical scope over time and emphasizes the need for comprehensive interventions at farm level.2
