Phylogenetic analysis of avian hepatitis E virus samples from European and Australian chicken flocks supports the existence of a different genus within the Hepeviridae comprising at least three different genotypes.

Abstract excerpt

Using PCRs that amplify regions of helicase and capsid genes, the presence of avian hepatitis E virus (avian HEV) was determined in samples from European and Australian chicken flocks (collected from 2005 to 2007 and 1986 to 1995, respectively). A total of 27 virus samples from 9 countries were analysed to determine the phylogenetic relationship following PCRs and nucleic acid sequencing of the helicase and...
