*HPeV, human parechovirus; nt, nucleotide; aa, amino acid; NA, not applicable.
†% identities were calculated by comparison with Harris (accession no. S45208), Williamson (accession no. AJ005695) and A308/99 (accession no. AB084913) reference strains for HPeV-1, -2 and -3 isolates, respectively.
‡Neutralization assays were performed by using specific HPeV-1 and -2 (formerly echovirus 22 and 23, respectively) antisera (MA Bioproducts, Walkersville, MD, USA).
