Bovine viral diarrhea virus (BVDV) is distributed in cattle worldwide and causes significant economic losses to the livestock industry. Identification and remove of BVDV persistently infected (PI) cattle is very important to control BVDV infection in cattle herd. The objective of this study is to investigate the infection status of BVDV infection in Korean native cattle (Bos taurus coreanae ) farms located in Jeonbuk State. From 2021 to 2022, a total of 1,497 samples were collected from 17 cattle farms and tested for BVDV antigen using a commercial ELISA kit. By the first ELISA testing, 24 cattle from six farms were positive for BVDV antigen, showing the farm-level or cattle-level prevalence of 35.3% or 1.6%, respectively. By the second ELISA testing which carried out with the first ELISA-positive samples after three-weeks, 12 cattle (0.8%) from five farms (29.4%) were positive for BVDV antigen, indicating these cattle were PI cattle. Genotypes of BVDV were determined with 12 BVDV-positive samples using a previously described RT-PCR assay and the results showed that 3 (25.0%) and 9 (75.0%) were confirmed to be type 1 and type 2, respectively. These results will be helpful to establish the effective control strategy for BVDV in cattle farms in Jeonbuk State.
