Abstract

The diagnostic accuracy of three ELISA tests (Herdcheck® Swine Salmonella, SALMOTYPE® Pig Screen, and PrioCHECK® Salmonella) was analysed. A low correlation between herd prevalence according to bacteriology and herd seroprevalence using the three ELISAs was found. Their estimated sensitivity (Se) and specificity (Sp) using a Bayesian approach was variable, with Herdcheck® Swine Salmonella showing the best overall accuracy (Se= 0.88; Sp= 0.74). All of the ELISAs overlooked an important proportion of Salmonella-infected pigs.
