Whole genome sequence analysis of porcine astroviruses reveals novel genetically diverse genotypes circulating in East African smallholder pig farms

Supplementary materials for the porcine astrovirus study in East Africa.

Table S1: Pairwise comparison of nucleotide sequence identities of the complete (near complete, U460) genomes of the seven (7) astrovirus field strains (bold) and with sequences of other astroviruses available in GenBank 

Table S2. Summary of nucleotide sequence identity matrix of the capsid protein (ORF2) among the seven (7) astroviruses field strains (bold) and the known reference strains in the GenBank using Clustal Omega

Table S3. Summary of amino acid sequence identity matrix of the capsid protein (ORF2) among the 7 astroviruses field strains (bold) and the known reference strains in the GenBank using Clustal Omega

Table S4: Estimates of evolutionary divergence between the East African PoAstVs and selected known AstV in the GenBank based on the amino acid sequences of complete ORF2 protein. The number of amino acid differences per site from between sequences is shown. Standard error estimate(s) are shown above the diagonal for our strains.

Table S5. Recommended potential linear antigenic epitopes predicted inside capsid protein (ORF2) of our field strains by SVMTriP web-based tool and corresponding antigenicity predicted by VaxiJen software
