Abstract: S1 gene of two strains of infectious bronchitis virus (IBV) isolated in Guangxi and Sichuan were amplified by RT-PCR technique and the cDNA sequences of those strains were determined and analyzed. Phylogenetic relations based on the nucleotide and amino acid sequences were analyzed among isolates and the reference strains in GenBank by DNAStar software. The results demonstrated that isolates had close relationship with J2, Q1 and T3, and less relationship with traditional IBV vaccine strains H120 and 4/91.

Key words: infectious bronchitis virus; PCR; sequence analysis
