Generation of “Color-flu” viruses: a powerful tool for in vivo imaging analyses

To better study influenza virus infection in vivo, we generated influenza A viruses (Color-flu viruses), which highly and stably produce multi-spectral fluorescent proteins in infected mice while maintaining their original pathogenicity. We demonstrated that Color-flu viruses are useful for flow cytometric analyses and for different types of microscopy.
