Fig. 1 — Phylogenetic analysis of our three IBV isolates with other IBV reference strains. Phylogenetic trees, based upon the S1 gene (A) and complete genomic sequences (B), respectively, were constructed using the maximum likelihood method with the general time-reversible nucleotide substitution model and bootstrap tests of 1000 replicates in the MEGA 6 program. Our three IBV isolates in this study are indicated by ★. GenBank accession numbers for the reference IBV strains are shown in parentheses after each strain name. The IBV strains used for cross-neutralization tests are given in bold.
