A serological enzyme-linked immunosorbent assay was developed using a synthetic peptide from the VP0 protein of human parechoviruses (HPeVs). Seroprevalence for HPeVs was 70% in children of < or = 5 years of age and 95% in adults. For children from whom serial sera were sampled, seropositivity increased from 22% to 88% between 2 and 24 months of age.

UNLABELLED Parechoviruses are human pathogens that cause diseases ranging from gastrointestinal disorders to encephalitis. Unlike those of most picornaviruses, parechovirus capsids are composed of only three subunits: VP0, VP1, and VP3. Here, we present the structure of a human parechovirus 1 (HPeV-1) virion determined to a resolution of 3.1 Å. We found that interactions among pentamers in the ...

Reverse transcription-PCR targeting the VP0 gene of human parechoviruses (HPeVs) was used to identify two isolates from two Japanese children's stool specimens. Molecular analysis revealed that these isolates belonged to HPeV type 4, and their nucleotide identity in the P1 region was 85.0%.

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.

Human parechoviruses (HPeVs) were detected by reverse transcription-PCR in 16.1% of 335 stool samples from children <6 years of age with enteritis in Salvador, Brazil. Whole genome sequencing of 1 sample showed a novel HPeV that has been designated as HPeV8.

Human parechoviruses (HPeV) circulate worldwide, causing a broad variety of symptoms, preferentially in early childhood. We report here the nearly complete genome sequence of a novel HPeV type, consisting of 7,062 nucleotides and encoding 2,179 amino acids. M36/CI/2014 was taxonomically classified as HPeV-17 by the picornavirus study group.

introduction : viral meningitis is an inflammation of the leptomeninges as a manifestation of central nervous system (cns) infection, and more than 85% of viral meningitis cases are caused by non-polio enteroviruses. molecular methods such as polymerase chain reaction (pcr) are increasingly used to detect and type non-polio enteroviruses. here, we describe the impact of these viruses on aseptic...
