Characterization of the Fetal Immune Response to PRRS

PRRSV causes abnormal development of immune function. This is believed to allow the virus to persist in carrier animals that remain relatively healthy. Such disregulation of the immune is a common feature of many viral infections. Good parasites exist by…

The influence of maternal antibody against porcine reproductive and respiratory syndrome virus (PRRSV) infection and the effect of a killed PRRSV vaccine in increasing the level of maternal antibody

PRRSV-positive sow herds can produce PRRSV-negative pigs. This phenomenon is important in herd stabilization against PRRSV-induced disease. One possible explanation of this phenomenon would be that MDAs provides protection against clinical disease and reduce virus levels in the pigs. However,…
