摘要
[ Objective] This study aimed to investigate pathological changes in various organs of piglets infected with classical swine fever and provide reliable basis for accurate diagnosis of classical swine fever. [ Method] By using paraffin embedding, section slicing and HE staining, histopathological changes in the heart, liver, spleen, lung, kidney and small intestine tissues of five diseased piglets were observed. C Result] Classical swine fever virus could lead to multiple visceral and mueosal hemorrhages, inflammatory cell infiltration, necrosis and other pathological changes. [ Conclusion ] Classical swine fever virus can further cause progressive degeneration and necrosis of different cells, resulting in immune injury.
