Identification of a Novel Astrovirus Associated with Bovine Respiratory Disease

Figure 1

Phylogenetic analysis of astrovirus. Phylogenetic trees were constructed by maximum likelihood analysis with 500 bootstrap replicates using MEGA11 software. Bootstrap values ≥70 are shown above the branches. GenBank accession numbers are indicated along with AstV host. The scale bar indicates 0.5 substitutions per site for Figure 1(a) and 1.0 substitution per site for Figure 1(b). ORF1ab amino acid sequence clades are arbitrarily labeled A-I. Clade B contains BAstV amino acid sequences identified in this study and highlighted in yellow (a) ORF2 amino acid sequence clades are arbitrarily labeled A-H. Clade F contains BAstV amino acid sequences identified in this study highlighted in yellow (b).
