Longitudinal changes in the number of IgG1 ELISA-positive young deer following implementation of an ELISA-based test-and-cull management strategy. Young deer (fawns) were screened by IgG1 ELISA to detect M. paratuberculosis infection at two ages, 6 to 8 months (gray bars) and 12 to 15 months (black bars). Data represent the number of fawns testing positive at each time point, following the implementation of a test-and-cull management strategy in 2002.
