Histopathological lesions of the lymph nodes (a, b) and lungs (c, d) from PCV3- and mock-inoculated piglets. The piglets infected with the PCV3 DB-1 isolate showed a small number of lymphocyte reduction and inflammatory cell infiltration in the lymph nodes (a), and epithelial cell proliferation, inflammatory cells infiltration, and thickened alveolar septum in the lungs (c). No obvious pathological lesions were observed in the lymph nodes (b) and lungs (d) of the mock-inoculated piglets.
