Abstract:
In this study, the complete genome of a novel polyomavirus detected in a great cormorant (Phalacrocorax carbo) was characterized. The 5133-bp-long genome of the cormorant polyomavirus has a genomic structure typical of members of the genus Gammapolyomavirus, family Polyomaviridae, containing open reading frames encoding the large and small tumor antigens, viral proteins 1, 2, and 3, and the X protein. The large tumor antigen of the cormorant polyomavirus shares 45.6-50.4% amino acid sequence identity with the homologous sequences of other gammapolyomaviruses. These data, together with results of phylogenetic analysis, suggest that this cormorant polyomavirus should be considered the first member of a new species within the genus Gammapolyomavirus, for which we propose the name "Phalacrocorax carbo polyomavirus 1".
