To address its value as a screening tool in the development of antiviral drugs, a recombinant influenza virus expressing green fluorescent protein (rPR8-GFP virus) was investigated in vitro and in vivo. The inhibition of viral growth by a neuraminidase inhibitor in the cells or lower respiratory tracts of mice could be visualized by the level of fluorescence. In addition, the rPR8-GFP virus exhibited high pathogenicity in mice. Taken together, these results suggest that the rPR8-GFP virus can be a useful tool for the rapid identification of antiviral drugs active against influenza viruses.
