Glomerular pathology in surviving pigs experimentally infected with African swine fever virus.
Twelve miniature pigs were inoculated with an attenuated African swine fever virus to study glomerular involvement in surviving pigs. In acute phase, kidneys were severely affected and displayed a glomerular capillary thrombosis with fibrin deposition in vascular lumen, detected by immunofluorescence. Fibrin-positive deposits were progressively cleared between one to three months after infection in surviving pigs. The histological picture in kidneys of surviving pigs, up to one post-infection year, showed a focal and segmental glomerulonephritis with hyalinosis, and IgM and C3 deposition was detected by immunofluorescence. Its pathogeny as an evolutive stage of acute glomerular injury is pointed out.
