Summary of ELISA Results. All the farms are showed: the position in the plot is given by the maximum number of gE (glycoprotein E) positive animals identified into the pools (x axis) and on the maximum ELISA results recorded among all tested pools. Black dots represent the results in agreement with Official IBR status; grey dots represent the 4 recorded IBR re-infection in expected gE-negative farms; white dots represents the 16 expected gE-positive farms which always resulted negative to gE indirect ELISA. The dotted lines indicate the threshold values of the gE indirect ELISA
