Bovine viral diarrhea virus (BVDV) is one of the most important viral pathogens of livestock and causes substantial economic losses to the livestock industry worldwide. BVDV is not necessarily species specific and is known to infect domesticated and wild ruminants. In the present study, BVDV infection was identified in two Saanen goats from one farm, and two different viral subtypes were found, BVDV-1a and BVDV-2a. Each isolate was closely related to cattle isolates identified in the Republic of Korea. The two sequences obtained in this study were not consistent with border disease virus (BDV). The incidence of BVDV in this farm apparently occurred in the absence of contact with cattle and may be associated with grazing. This study demonstrates that BVDV infection may be possible to transmit among goats without exposure to cattle. Therefore, this result indicates that Saanen goats may act as natural reservoirs for BVDV. This is the first report of BVDV-1a infection in a Saanen goat.
