Complete genome sequence of a novel type of human parechovirus strain reveals natural recombination events

J Virol. 2012 Aug;86(16):8892-3. doi: 10.1128/JVI.01241-12.

Abstract

Human parechoviruses (HPeVs) are a species in the Parechovirus genus of the Picornaviridae family. We report a complete genome sequence of a novel HPeV strain, CH-ZJ1, that was found in an infant with gastroenteritis in Zhenjiang City, China. The complete genome consists of 7,298 nucleotides (nt), excluding the 3' poly(A) tail; the open reading frame is mapped between nucleotide positions 654 and 7211 and encodes a 2,185-amino acid (aa) polyprotein. The phylogenetic tree obtained for the complete genome of this HPeV strain and the other HpeV strains available in GenBank indicated that CH-ZJ1 is intervenient between HpeV type 4 (HpeV4) and HpeV5. Phylogenetic analysis based on the 3D and VP1 genes reveals two incongruent trees. Recombination detection indicated that CH-ZJ1 might be a recombinant which was produced by more than one genomic recombination event that occurred among HPeV1, HPeV4, and HPeV3 strains.
