Table 1 Relationship between neutralization and opsonization titres

From: Interplay of foot-and-mouth disease virus, antibodies and plasmacytoid dendritic cells: virus opsonization under non-neutralizing conditions results in enhanced interferon-alpha responses

anti-O Manisa serum
Serotype Viral strain NT in log10 OT* in log10
Type-O O UKG 2001 4.1 4
  O VietNam 7/97 3.1 3
Type-A A Brazil 10/93 < 1.5 4
  A Turkey/99 < 1.5 2
Type Asia-1 Asia-1 Turkey/99 < 1.5 2
Type-C C1-Noville < 1.5 0
  1. * Opsonizing titres representing minimum serum dilution able to enhance IFN-α responses by pDC (calculated from 3-5 independent experiments as described in Figure 6).
