Phylogenetic analysis of partial 5′UTR sequences of (A) HPeV strains from 47 patients, (B) 3 AiV and 1 SalV strains from 4 patients. The trees were inferred from 5′UTR data by the neighbor-joining method, with bootstrap values calculated from 1000 trees. (A) 145 and (B) 188 nucleotide positions in each 5′UTR were included in the analysis. The scale bar indicates the estimated number of substitutions of 20 nucleotides as indicated. The virus strains detected in this study are highlighted in grey. Virus abbreviations (GenBank accession numbers shown in parentheses): AEV, avian encephalomyelitis virus (NC_003990); AiV, Aichi virus (NC_001918); CPDV, canine picodicistrovirus (JN_819202); DHV1, duck hepatitis virus 1 (NC_008250); ERBV1, equine rhinitis B virus 1 (NC_003983); FMDV-A, foot-and-mouth disease virus-A (JQ_082983); HAV, hepatovirus (NC_001489); HCosV-A1, human cosavirus A1 (FJ_4389020); EV-A, human enterovirus A (AY_697458); HPeV2, human parechovirus type-2 (AJ_005695); PTV1, porcine teschovirus 1 (NC_003985); SafV, saffold virus (EF_165067); SalV, salivirus (GQ_179640); SePV1, seal picornavirus 1 (NC_009891); SSV, simian sapelovirus (AY_064708); SVV, Seneca Valley virus (NC_011349); THV, turkey hepatitis virus (HQ_189775).
