Case Report: Recently a 20-day-old layer flock with mortality has been submitted to the PCR Lab. Infectious Bronchitis Virus (IBV) has been detected in the clinical samples. Results: A phylogenetic tree based on a partial S1 gene sequence showed Iranian IBV variant located in LX4-type cluster. This cluster include all QXIBV-type detected in China and European countries. The highest sequence homology (> 99%) was found with that of a group of the Chinese QX but less similarity with European QX-like (>95%) and another Chinese QXIBV (>94%). Conclusion: Comparison of Nucleotides sequence with H120 and 4/91 IB vaccines shows only 76.9 and 79.7 identity, respectively.
Keywords: Infectious Bronchitis Virus (IBV), Clinical Samples, Phylogenetic tree
