Full-length genome reveals genetic diversity and extensive recombination patterns of Saudi GI-1 and GI-23 genotypes of infectious bronchitis virus.

ABSTRACT:

Background

Despite numerous genetic studies on Infectious Bronchitis Virus (IBV), many strains from the Middle East remain misclassified or unclassified. Genotype 1 (GI-1) is found globally, while genotype 23 (GI-23) has emerged as the predominant genotype in the Middle East region, evolving continuously through inter- and intra-genotypic recombination. The GI-23 genotype is now enzootic in Europe and Asia.

Methods

Over a 24-month period from May 2022 to June 2024, 360 samples were collected from 19 layer and 3 broiler poultry farms in central Saudi Arabia. The chickens exhibited reduced laying rates and symptoms such as weakness and respiratory distress, while broilers showed respiratory issues. Samples, including tracheal swabs and various tissue specimens, were pooled, ho
