Fig. 4From: Mapping geographical areas at risk for tick-borne encephalitis (TBE) by analysing bulk tank milk from Swedish dairy cattle herds for the presence of TBE virus–specific antibodiesCorrelation between mean herd serum and bulk tank milk TBEV antibodies. The dot plot graph illustrates the modified indirect ELISA (mE) S/P % values of the analysed bulk tank milk and the mean herd serum sampled from 359 cows from 11 herds. Pearson correlation test yields a coefficient of determination of R2 = 0.925; (P < 0.001)Back to article page
