Abstract

In 2011, several herds in Youngju city in Gyeongbuk province underwent an outbreak of bovine viral diarrhea virus (BVDV) causing high morbidity and mortality. Genetic analysis revealed that two subgenotypes of BVDV-1b(n = 21) and BVDV-2a (n = 7) were identified. The BVDV-1b subgenotype was most frequently detected from our field cases and BVDV-2a subgenotype was also identified in this outbreak. These BVDV-1b infections showed severe acute clinical manifestations similar to BVDV-2 infection. This result reports the detection of BVDV-1b associated with an acute and fatal outbreak of BVDV in Korean indigenous calves.
