Immunofluorescence analysis of MDCK cells infected with recombinant viruses. (A) Recombinant influenza A viruses expressing recombinant influenza B virus NAs. Subpanels: A and D, wild-type influenza B/Yamagata virus, B and C, wild-type influenza A/WSN virus; E and F, WSN-BNA virus; G and H, WSN-BNA/A65 virus; I and J, WSN-BNA/ACT virus; K and L, WSN-BNA/ACT-ATM virus. (B) Recombinant influenza A virus expressing the HA ectodomain of influenza B virus. Subpanels: A and B, mock infection; C and D WSN-BHA/ACT-ATM virus. α Flu B NA and α Flu B HA, monoclonal antibodies recognizing influenza B/Yamagata virus NA (9A6) or HA (15B6), respectively; α Flu A, polyclonal rabbit antiserum (i.e., 8236) raised against A/WSN virus.
