Divergent picornavirus from a Turkey with gastrointestinal disease

Abstract

A novel picornavirus, turkey avisivirus (TuASV), was identified from the feces of turkeys (Meleagris gallopavo) with gastrointestinal disease from a farm in Indiana. Its genome organization is as follows: 5= untranslated region (UTR)IRES-II [VP0, VP3, VP1, 2A, 2B, 2C, 3A, 3B, 3Cpro, 3Dpol] 3= UTR-poly(A). TuASV shares only 34% (P1), 36% (P2), and 35% (P3) amino acid identities with avihepatoviruses, indicating that it potentially represents a novel picornavirus genus.
