Echoviruses (EV) 1 and 8 were originally considered to be distinct serotypes, but more recently have been considered strains of the same virus. In experiments with chimeric recombinant fusion proteins, both viruses bound to the I domain of the integrin VLA-2, and both required the same receptor residues for attachment. A full-length, infectious cDNA clone encoding EV1 was obtained; its nucleotide sequence was determined, as were the sequences encoding the EV8 capsid. EV1 and 8 show 94% amino acid identity within the capsid region and are more similar to each other than to any other human picornavirus.
