  1. a The distribution of α-2,3 and α-2,6 influenza receptors was evaluated using lectin immunohistochemistry.
  2. b The pattern of viral attachment was performed using virus histochemistry and the A/Mallard/Netherlands/13/08 (H4N5) and A/Netherlands/35/05 (H1N1) viruses.
  3. c Media of the results obtained in the epithelia lining (columnar epithelial cells and goblet cells).
  4. d -: negative; +: low; ++: moderate; +++: strong.
