The genomic RNA of a novel chicken astrovirus was determined. The full length sequence is 7520 nucleotides and encodes three open reading frames (1a, 1b, 2) for three proteins. The genomic organization was similar to other astroviruses with two exceptions. The open reading frame of the RNA-dependent RNA polymerase contains its own start codon which is(More)

Pigs are believed to be one of the important sources of emerging human and swine influenza viruses (SwIV). Influenza virus conserved peptides have the potential to elicit cross-protective immune response, but without the help of potent adjuvant and delivery system they are poorly immunogenic.
