Fig. 5From: Complete genomic characteristics and pathogenic analysis of the newly emerged classical swine fever virus in ChinaGross and histological lesions of tonsils, lungs and kidneys of piglets in different groups. Piglets infected with Shimen (a1-a3) or HLJ1 (b1-b3) showed obvious necrosis, hemorrhaging or hemorrhagic spots than mock-infected (c1-c3) piglets. Histopathology of tonsils, lungs and kidneys of Shimen- (a4-a6), HLJ1-infected (b4-b6) piglets manifested partial lymphoid follicle atrophy, interstitial pneumonia or lymph histiocytic infiltrates than control (c4-c6). Viral antigen of CSFV was detected in the tonsils of piglets in Shimen- or HLJ1-infected groups by means of IHC staining (a7, b7). The tonsils of piglets in control group were negative for CSFV (C7).
