| Outline of Final Research Achievements |
Bovine viral diarrhea virus (BVDV) infection is one of the most important causative agent for digestive tract disease. Intrauterine infection to the fetus without effective immune response causes persistent infection and this state related to various pathologic states. This research revealed the precise pathobiology of newly recognized diseases associated with BVDV persistent infection: 1) leukodystrophy characterized by severe gliosis and hypomyelinogenesis, and 2) systemic glomeruloid angiopathy characterized by intramural proliferation of vascular endothelial cells and smooth muscle cells. In the present research, we also examined whether BVDV persistent infection relate to other uncleared disease conditions, including vascular diseases with fibrinoid change which is one of the characteristic finding for BVDV infection, and central nervous system diseases. Unfortunately, however, we could not find new BVDV persistent infection-related disease.
