Figure 1From: Assay dependence of Brucella antibody prevalence in a declining Alaskan harbor seal (Phoca vitulina) populationSerological prevalence of anti– Brucella antibodies for different tests. The percentage of positive reaction is shown with a 95% upper and lower confidence interval. Assays for antibodies towards B. ovis and B. canis did not detect antibodies in any samples (data not presented).Back to article page
