Influenza A viruses (IAVs) cause epidemics and pandemics that result in
considerable financial burden and loss of human life. To manage annual IAV
epidemics and prepare for future pandemics, an improved understanding of how IAVs
emerge, transmit, cause disease and acquire pandemic potential is urgently
needed. Fundamental techniques essential for procuring such knowledge are IAV
isolation and culture from experimental and surveillance samples. Here we present
a detailed protocol for IAV sample collection and processing, amplification in
chicken eggs or mammalian cells, and identification from samples containing
unknown pathogens. This protocol is robust, and it allows for the generation of
virus cultures that can be used for downstream analyses. Once experimental or
surveillance samples are obtained, virus cultures can be generated and the
presence of IAVs can be verified in 3-5 d via reverse-transcription (RT)-PCR or
hemagglutination assay. Increased time frames may be required for less
experienced laboratory personnel, or when large numbers of samples will be
processed.
