Here we describe the detection of influenza A virus sequences from 1918 obtained from three fomalin-fixed lung specimes preserved within the pathology collection of the medical museum of the Charite,
The PR8 and PR8mut viruses were produced by reverse genetics using the pHW191-PB2, pHW192-PB1, pHW193-PA, pHW194-HA, pHW195-NP, pHW196-NA, pHW197-M (wild type PR8) or pHW197-Mmut (PR8mut), and pHW198-
