- Abstract
In this study, the complete genome of a novel picornavirus called harrier picornavirus 1 (HaPV-1) strain harrier/MR-01/HUN/2014 (KY488458) was sequenced and analysed from a cloacal sample of a threatened, carnivorous wild bird, western marsh harrier ( Circus aeruginosus). HaPV-1 was detectable from 2 of the 3 samples from harriers. HaPV-1 is phylogenetically related to megriviruses (genus Megrivirus) from domestic chicken, turkey and duck, showing a similar genome organization pattern; it also has an avian picornavirus-like 'Unit A' motif in the 3' UTR. Unlike the type-IV internal ribosomal entry site (IRES) of megriviruses, HaPV-1 is predicted to contain a type-II-like IRES, suggesting modular exchange of IRES elements between picornavirus genomes.
