Fig. 2From: Comparative features of infections of two Massachusetts (Mass) infectious bronchitis virus (IBV) variants isolated from Western Canadian layer flocksPhylogenetic tree of 45 IBV whole genome sequences including Western Canadian Mass IBV isolates. A maximum likely hood phylogenetic tree was inferred based on the whole genomes of 15AB-01 and 15SK-02 isolates of IBV and 43 IBV genome sequences retrieved from GenBank using RAxML with GTR GAMMA nucleotide substitution model with 1000 bootstrap iterationsBack to article page
