B. abortus strain populations are similar within a lymph node but different between animals. Heat map of (A) Jaccard and (B) Bray–Curtis dissimilarity values for each pair of samples (1 = dissimilar, 0 = similar). For the inoculum (inoc), each individual replicate (A–C) and the sum of the three replicates (total) were compared. Horizontal lines separate samples from each animal. Samples are colored as in Fig. 1. As in Fig. 3, Bray–Curtis dissimilarity scores between calf 4 Left_A and calf1 Left quadrants reflect contaminating PCR signal.
