Abstract

The placenta in cattle prevents in utero transfer of maternal immunoglobulins and leukocytes to the fetus. The fetal immune system, on the other hand, can be exposed to pathogens that cross the placental barrier and mount an immune response to bovine leukosis virus (BLV), infectious bovine rhinotracheitis (IBR), bovine viral diarrhea (BVD) types 1 and 2, Neospora caninum (NC), Leptospira hardjo (LH), and Leptospira Pomona (LP). The objective of this study was to determine the apparent prevalence of congenital infections to common infectious pathogens in calves.
