Title: Genetic Variance Analysis on S1 Gene Hypervariable Region of Infectious Bronchitis Virus Strain from Hainan Province
Abstract: S1 gene of seven strains of infectious bronchitis virus (IBV) isolated in Hainan were amplified by RT-PCR 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 the isolates had close relationship with the CK/CH/LNM/05 and less relationship with traditional IBV vaccine strains H120 and Ma5.
