Despite this, acute infections with BVDV can persist for months or years after the removal of the PI source despite repeated screening for PIs and tight biosecurity measures. Recent evidenc...

Pestivirus infections are commonly diagnosed in cattle but are relatively uncommon in other ruminant species in Australia. Virus isolation is a very reliable technique for detecting pestivirus in specimens, especially when group reactive monoclonal antibodies are used with immunoperoxidase staining to detect non-cytopathogenic virus. Care must be taken to prevent adventitious pestivirus contami...
