Figure 2. Phylogenetic cluster showing relatedness of Clostridium difficile clinical, pig and farmer isolates, the Netherlands, 2008–11 (n=4).

Figure 2

A. Geographical map showing the location of the isolates present in the phylogenetic cluster shown in panel B. Blue dot represents a hospital (Breda), red dots represent the two pig farms (R’donksv. and Oirschot).

B. Zoom-in on a phylogenetic cluster containing highly related isolates from different sources (swine, farmer and clinical isolates). The numbers on the tree branches represent the number of single-nucleotide polymorphisms differences in the cluster, the tip labels are coded with city (Breda) followed by two numbers that represent year of isolation (’08 ⩠ 2008).
