Figure 2From: Development of a virus neutralisation test to detect antibodies against Schmallenberg virus and serological results in suspect and infected herdsDistribution of titres in non-infected sheep (n = 156) and cattle (n = 192) (bars, left axis). Serum samples were tested in two fold dilutions from 1:4 until 1:128. Specificity of the VNT in sheep and cattle serum samples, depending on cut-off value (a cut-off value of 4 meaning that all titres of 4 and above are considered positive, etc.) for sheep and cattle is shown with the lines (right axis).Back to article page
