Results of a liver inspection of all investigated animals (n = 844 livers), b liver inspection of animals that were also screened by copromicroscopy and ELISA (n = 177 animals). Each bar indicates the corresponding farm of the examined animals. Positive livers showed different grades of milk spots: low (< 5 visible milk spots on the surface), medium (5–20 milk spots), high (> 20 milk spots). c Copromicroscopical analysis of the same animals as in (b) by modified McMaster egg counting. Only qualitative results are shown. d ELISA for anti-Ascaris suum serum antibody detection from the same animals as in (b) and (c). ODR values > 0.6 were considered as positive, ODR < 0.4 as negative, and values 0.4–0.6 as doubtful
