MuAstV STL is a member of a putative third genogroup of mamastroviruses. Genomic sequences corresponding to ORF2 were translated and aligned. Phylogenetic analyses were performed using maximum-parsimony (MP) and maximum-likelihood (ML) methods with 1,000 bootstrap replicates. The bootstrap support (ML/MP) is indicated adjacent to each branch of the best-scoring ML tree where significant. Corresponding sequences from representative avastroviruses were included for comparison. GenBank accession numbers immediately precede each sequence name.
