Microscopic pictures of the H&E stained lung sections showing no lesion in G1. Severe congestion (black arrows), perivascular edema (yellow arrow) and heterophils infiltration (blue arrow), necrosis of epithelial cells lining secondary bronchi and parabronchi (arrowheads) were shown in G2 subjected to H9N2 challenge. Perivascular hemorrhage (red arrows) along with narrowing lumen of parabronchi (*) were shown in G3 supplemented with vitamin C + AG and subjected to H9N2 challenge. Mild congestion (black arrows) was shown in G4 vaccinated and subjected to H9N2 infection. Narrowing lumen of few parabronchi (*) and very mild congestion (black arrows) were shown in G5 vaccinated, supplemented with vitamin C + AG and subjected to H9N2 challenge. Scale bar: 100um. Statistical analysis showed significant reduction of total lung lesions scores in treated groups when compared to untreated group G2. Different small alphabetical letters mean significant when P < 0.05
