Fig. 1

Rooted maximum likelihood tree of B. afzelii based on concatenated sequences of eight MLST housekeeping genes. A total of 149 STs corresponding to 308 B. afzelii isolates grown in vitro from human samples were used in this study, including data previously published by Coipan et al. [15] (n = 126) and data from the MLST database (n = 121) [13, 22]. The total number of strains associated with each ST is indicated in brackets next to the ST. Type strains (T) of B. afzelii (strain VS461) and B. garinii (strain 20047) were also included in the dataset. The bootstrap values obtained on highly supported nodes after 1000 repetitions (with ≥ 70% support) are given below the branches. The grouping of STs into CCs defined by goeBURST analysis at the DLV threshold is indicated by brackets in the case of CC1 to CC12. STs corresponding to singletons are underscored. All other STs belong to the CC0 distributed throughout the tree. The type of infection associated with each strain is indicated by a geometrical shape next to the STs, whereas the geographical origin is indicated by a color (see the legend). Black rectangles give a section of the tree for the sake of better legibility
