A prevalence study on Map infection in dairy goats was carried out in France by using a serological ELISA. One hundred and five herds were randomly selected in different regions and all the goats of at least 6 months were sampled (n= 11,847). As the accuracy of the ELISA test was previously estimated, true prevalences were estimated by conversion from apparent prevalences via the Rogan-Gladen estimator. As herd level sensitivity and specificity are a function of sample size, and as the herd size varied considerably, the herd true prevalence was estimated using a weighted average according to herd size strata. At herd level apparent prevalence and estimated true prevalence were 55.2% and 62.9%, respectively. In positive herds, the average within-herd apparent prevalence was 5.9% and estimate of the average within-herd true prevalence was 11.1%. Results provided information about prevalence of Map infection in French goat herds, with respect to designing a Map infection control program in French goat herds
