Human parechovirus type 1, 3, 4, 5, and 6 detection in picornavirus cultures

Picornavirus cultures that could not be typed in neutralization assays were analyzed by VP1 reverse transcription-PCR (RT-PCR) and a virus discovery tool (VIDISCA). Human parechoviruses (HPeVs) were frequently identified, among which were the uncommon isolates HPeV-4, HPeV-5, and HPeV-6. The HPeV-5 isolate could be amplified only by VIDISCA and not by VP1 RT-PCR.
