An UPGMA dendrogram was constructed by START 2.0 software using the unweighted pair-group method and the arithmetic average method (UPGMA). The split decomposition was done with SplitsTree and START 2.0 software on the MLST

website ( http://​eburst.​mlst.​net/​). LEE011 chemical structure Minimum-spanning tree analysis of the STs from all isolates was done using Prims’s algorithm in the BioNumerics software according to region and source separation (version 6.0, Applied-Maths, Sint Maartens-Latem, Belgium).
