Figure 3From: Distribution patterns of influenza virus receptors and viral attachment patterns in the respiratory and intestinal tracts of seven avian speciesInfluenza receptor distribution and pattern of viral attachment in the large intestine. Composite bright field microscope images comparing the distribution of α-2,3 and α-2,6 receptors, demonstrated by means of MAAII and SNA lectin histochemistry, with the pattern of viral attachment of the avian influenza A/Mallard/Netherlands/13/08 (H4N5) virus and the human influenza A/Netherlands/35/05 (H1N1) virus, demonstrated by means of virus histochemistry, in the large intestine of the chicken (A1-A4), common quail (B1-B4), red-legged partridge (C1-C4), turkey (D1-D4), golden pheasant (E1-E4), ostrich (F1-F4), and mallard (G1-G4).Back to article page
