Lung gross lesion, histopathological and immunohistochemical examinations. Lung consolidation was observed in positive control and TJM-F92 vaccinated pigs (B, C) but not in mock-infected and rJS-ORF2-6-CON inoculated pigs (A, D). Interstitial pneumonia with infiltration of mononuclear cells could be observed in positive control and TJM-F92 vaccinated pigs (F, G) but not in mock-infected and rJS-ORF2-6-CON inoculated pigs (E, H). PRRSV-specific antigen could be observed in all PRRSV-infected pigs (marked by the black arrows) (J, K, L) but not in mock-infected pigs (I).
