Nucleotide similarity matrix and heat maps of 23-selected reference strains and 2 current Mass IBV isolates. Full genome sequences of Western Canadian isolates (15AB-01 and 15SK-02) were aligned with 23 reference sequences retrieved from the GenBank. The resulting genetic distance matrix along with heat maps based on the similarity index is shown
