[eradication of paratuberculosis in dairy herds: determination of the initial herd prevalence and modelling of prevalence development].a prerequisite for the success of any eradication programme is the accurate determination of the initial herd prevalence as well as a herd-specific prediction of prevalence development. this prerequisite is not currently given for the eradication of paratuberculosis in infected herds. in the work presented a method to predict the initial paratuberculosis prevalence in infected herds is presented; it is based on the formation of two groups (elisa-positive and negative) and the determination of ge ...200111505846
detection of mycobacterium avium ssp. paratuberculosis in ileocaecal lymph nodes collected from elderly slaughter cows using a semi-nested is900 polymerase chain reaction.the aim of this study was to investigate the occurrence of subclinical mycobacterium avium spp. paratuberculosis (map) infections at slaughter by testing ileocaecal lymph nodes with a semi-nested is900 pcr. tissue samples were available within the framework of a parallel study investigating bse-susceptibility factors in members of bse-cohorts in the german federal state of lower saxony. ileocaecal lymph nodes were collected over a 2-year sampling period from 99 slaughter cattle of a mean age of ...201121775077
