Abstract: Global chicken industry is harmed by the highly contagious avian infectious bronchitis virus (IBV). In this work, we evaluated the frequency of IBV in commercial poultry flocks from three significant producing locations in Iraq and looked into the tropism of circulating IBV genotypes to three distinct physiological systems (Respiratory, digestive, and urinary/reproductive.The aim of this study was to evaluate the frequency of avian infectious bronchitis virus (IBV) in commercial poultry flocks from three significant producing locations in Iraq and to investigate the tropism of circulating IBV genotypes to three distinct physiological systems (Respiratory, digestive, and urinary/reproductive.In the Midwest, northeast, and south of Iraq, samples were gathered from 432 commercial flocks (198 broilers and 234 breeders), and IBV identification was carried out using reverse-transcription, real-time PCR of the 5′ untranslated region. According to the findings, IBV was present in 41.4% of the flocks, with broilers experiencing a greater frequency (24.8%) than breeders (16.8%). The prevalence of IBV-positive flocks was comparable across geographic regions, and the digestive and respiratory systems of broilers as well as the breeders' gastrointestinal tracts were the most often seen sites for reverse transcription.Reverse-transcription nested PCR was used for genotyping, and the S1 gene was sequenced from a sample of 79 IBV-positive flocks (45 broilers and 34 breeders). The Iraqi variant genotype, which was mostly discovered in the intestinal tract of commercial chicken flocks in the three key producing regions of Iraq, infected the majority of flocks.
