Individuals fall into distinct shedding clusters. A Dendrogram showing how individuals were clustered into four shedding clusters using hierarchical clustering: low-shedders (LS; n = 224), low-intermediate-shedders (LIS; n = 206), high-intermediate-shedders (HIS; n = 118) and high-shedders (HS; n = 99). B Log mean Bartonella spp. infection intensity as a function of shedding cluster. Large circles are means; small circles are individuals; bars show plus or minus two standard deviations
