All isolates are L. interrogans except those belonging to the L. kirschneri clade, as indicated. Figure 2a. The tree was constructed using the Neighbour-Joining method (K-2-P) as implemented in MEGA ver 3.1 [12]. The numerical dominance of ST34 is indicated by the shaded area. Isolates recovered from Udon Thani are represented throughout the tree (red diamonds). The highlighted STs are discussed in the text. Figure 2b was constructed using MEGA ver 3.1 [12], and shows a neighbour-joining tree based on these highlighted STs only in order to clarify the branching order. Confidence in the topology of this tree was gauged by bootstrap resampling (1,000 times), and the scores are shown on the nodes.
