FIG 3.

SNPs accumulated from the most recent common ancestor (MRCA) of Klebsiella pneumoniae. Two variants of a K. pneumoniae descendant (DESC) occurred in the same patient. One of the two descendant (DESC2) variants was considered to be in close contact with Achromobacter xylosoxidans KUN4507, and the plasmid harboring the MBL gene (pKUN4507_1) was transferred from A. xylosoxidans KUN4507 to DESC2. The red bar indicates the duration of the contact of A. xylosoxidans KUN4507 with DESC2. HPD, highest posterior density; POD, postoperative day.
