چکیده

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.
