FIGURE 3.

Minimum spanning phylogenetic trees derived from multilocus sequence typing (MLST) using the integrated concatenated sequences of seven housekeeping genes: argH, cya, glpK, gnd, murC, pta, and purH (BioNumerics V.6.6, Applied Maths). Strains clustered together by the seven-gene MLST scheme were depicted as circles, strains from different hospitals were depicted by different colours with shades of green representing southern Taiwan, shades of yellow representing central Taiwan, and shades of red representing northern Taiwan.
