Correlation 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)
