Relationship between the Percentage of Positivity (PP) values from the pre- and post-heated serum samples measured with the ELISA system to detect anti-T. gondii antibodies. (a) PP values of the 19 sera from pigs experimentally infected with T. gondii. Each circle represents the data for each wild boar. (b) ROC curve used for calculating the cut-off value for the post-heated samples. The curve was created on the assumption that the results from the pre-heated samples are correct.
