Fig. 3From: Molecular characterization of isolated infectious bronchitis viruses from affected vaccinated broiler flocks in SyriaPhylogenetic tree based on alignment of partial S1 gene sequences of ten Syrian IBV variants (bold line), vaccine strains (red line) and seventeen Isolates/strains retrieved from GenBank. The phylogenetic tree was constructed using of Geneious 4.8.4 software with neighbor-joining method using of 500 bootstrap replicatesBack to article page
