Genetic characterization of a novel picornavirus distantly related to the marine mammal-infecting aquamaviruses in a long-distance migrant bird species, European roller (Coracias garrulus).

ABSTRACT: Despite the continuously growing number of known avian picornaviruses (family Picornaviridae), knowledge of their genetic diversity in wild birds, especially in long-distance migrant species is very limited. In this study, we report the presence of a novel picornavirus identified from one of 18 analysed faecal samples of an Afro-Palearctic migrant bird, the European roller (Coracias garrulus L., 1758), which is distantly related to the marine-mammal-infecting seal aquamavirus A1 (genus Aquamavirus). The phylogenetic analyses and the low sequence identity (P1 26.3?%, P2 25.8?% and P3 28.4?%) suggest that this picornavirus could be the founding member of a novel picornavirus genus that we have provisionally named 'Kunsagivirus', with 'Greplavirus A' (strain roller/SZAL6-KuV/2011/HUN, GenBank accession no. KC935379) as the candidate type species.
