This year, we will develop two kinds of DNA chip diagnosis kits for vesicular disease of swine and classical swine fever virus. The DNA chip diagnosis kits could be used to differential diagnosis for vesicular disease of swine including FMDV O、A、C、Asia-1、SAT1、SAT2 and SAT3 seven serotypes, vesicular stomatitis virus three serotypes and swine vesicular disease virus. The DNA chip diagnosis kits for classical swine fever virus could be used to differential diagnosis for classical swine fever virus, bovine viral diarrhea virus, border disease virus, infectious bovine rhinotracheitis and porcine circovirus.
