The full-length genome of an Italian IBDV strain (ITA) was sequenced and compared with available full length IBDV sequences. Amino acid residues previously observed in very virulent IBDV strains, as well as amino acid residues typical of non-virulent IBDV strains, were observed in the amino acid sequence of the ITA strain. By the phylogenetic analysis, ITA strain did not show a close relationship with other known IBDV strains, neither recombination or reassortment events. The currently available molecular data confirmed that ITA strain is a new genotype. Further investigations are needed to clarify its origin.

Abstract

The full-length genome of an Italian IBDV strain (ITA) was sequenced and compared with available full length IBDV sequences. Amino acid residues previously observed in very virulent IBDV strains, as well as amino acid residues typical of non-virulent IBDV strains, were observed in the amino acid sequence of the ITA strain. By the phylogenetic analysis, ITA strain did not show a close relationship with other known IBDV strains, neither recombination or reassortment events. The currently available molecular data confirmed that ITA strain is a new genotype. Further investigations are needed to clarify its origin.
