Abstract excerpt

The infectious bronchitis virus (IBV) causes significant losses in commercial poultry egg and meat production. Since its first emergence, the genotype GI-23 (Variant 2) has progressively increased its geographical distribution, shown a significant virulence, and challenged the vaccine efficacy. Global viral transmission could be attributed to multiple factors including human related activities such as poultry and...
