Phylogenetic analyses of the amino acid sequences of PoAstV-3 isolates (bold) from 3 symptomatic newly weaned pigs (GD-1, GD-3, and GD-5; see Table 1) from a farm in Hungary compared with reference isolates. A) ORF1a; B) ORF1b; C) ORF2. We included in the analysis available strains of the closest relatives (identified by blastx search [https://blast.ncbi.nlm.nih.gov/Blast.cgi]) of neuroinvasive PoAstV-3, all of the known porcine astroviruses with available complete coding sequences, all of the r

Figure 2. Phylogenetic analyses of the amino acid sequences of PoAstV-3 isolates (bold) from 3 symptomatic newly weaned pigs (GD-1, GD-3, and GD-5; see Table 1) from a farm in Hungary compared with reference isolates. A) ORF1a; B) ORF1b; C) ORF2. We included in the analysis available strains of the closest relatives (identified by blastx search [https://blast.ncbi.nlm.nih.gov/Blast.cgi]) of neuroinvasive PoAstV-3, all of the known porcine astroviruses with available complete coding sequences, all of the representative astrovirus strains with neurotrophic potential (white arrows), and some representative astrovirus sequences; GenBank accession numbers are in brackets. Gray boxes indicate the Virginia/Human-Mink-Ovine clade, which contains most of the neurotrophic astroviruses. Scale bars indicate amino acid substitutions per site. AAstV, avastrovirus; AstV, astrovirus; GG, genogroup; MAstV: mamastrovirus; ORF, open reading frame; PoAstV-3, porcine astrovirus type 3.
