BVDV/MD
|
Infection of a pregnant cow with noncytopathic BVDV during early gestation results in in-utero infection of the developing fetus
Cow recovers from infection by making antibody. Fetus survives infection, becomes immunotolerant to the virus and no antibody is produced Apparently normal calf is born with persistent viral infection Calf reaches adulthood, becoming a lifelong carrier. Superinfection with a cytopathic BVDV of either endogenous origin (mutation of resident noncytopathic virus) or exogenous source can occur Due to immunotolerance, animal is unable to mount an effective immune response to control the cytopathic virus and succumbs to muscosal disease Step 1 - NCP virus in utero infection - Immunological tolerance Step 2 - Superinfection with CP virus - cell destruction, no immune response - death (MD) |
