title: Survey on vertical infection of bovine viral diarrhea virus from fetal bovine sera in the field.
abstract: Bovine viral diarrhea virus (BVDV) isolation and antibody survey were performed using 2,758 fetal bovine sera (FBS) collected from slaughterhouses in New Zealand, Australia and the Dominican Republic, and then sent to Japan to manufacture commercial serum for cell culture use. FBS in the Dominican Republic were pooled for each several individuals, and those collected in other countries were separated according to each individual and subjected to the tests. BVDV was isolated from 25 (0.91%) FBS, and the BVDV antibody was detected in 44 (1.60%) FBS. The survey on 139 sets of paired sera of a dam and her fetus revealed that neither the BVDV antibody nor BVDV was detected in all FBS from BVDV antibody-positive dams.
