Fig. 4From: Cul o 2 specific IgG3/5 antibodies predicted Culicoides hypersensitivity in a group imported Icelandic horsesCul o 2 specific IgG3/5 antibodies in serum of allergic and non-allergic horses. IgG3/5 antibodies in serum of allergic (n = 9) and non-allergic (n = 7) horses were measured using a Culicoides allergen multiplex assay. Horses were imported to the US in the beginning of year 1 (arrow). The areas surrounded by dotted lines represent the natural exposure times to Culicoides midges during the two-year study period.
