First descriptive study of an outbreak of Border disease in a sheep flock in Austria - a high risk factor for Bovine viral diarrhea virus free cattle herds: a case report

Described is the first outbreak of Border disease in a sheep flock in Austria and its impact on the cattle housed on the same farm. Border disease virus infected sheep are a high risk for pestivirus introduction in susceptible cattle herds and should therefore induce a complete revision of the Austrian Bovine viral diarrhea virus program.
