The serum has been diluted to give a low positive result in ELISA and VNT.\n4\nA 1:40 dilution of a serum collected 21 dpi from a pig infected with swine vesicular disease virus strain UKG 27/72\nA low-positive serum defining the lowest level of antibodies that EU National Reference Laboratories should consistently score positive by ELISA and virus neutralisation.\nEquivalent to serum RS 01-04-94\n5\nSerum collected four dpi from a pig infected with swine vesicular disease virus strain UKG 27/72 (neat)\nA low-positive serum from a pig soon after infection.\n6\nSerum collected five dpi from a pig infected with swine vesicular disease virus strain UKG 27/72 (neat)\nA low-positive serum from a pig soon after infection.",
