Diversity of Tn1546 transposon types among E. faecium VanA isolates. Position of primers used in PCR mapping and sequencing indicated by arrows with primer names; open rectangles, transposon genes; stars, positions of point mutations; analyzed areas of the transposon shadowed; dashed lines, deletions in the left arm of the transposon; filled rectangles, deletions within the transposon; vertical arrow, triangles with arrows, the IS positions; single-nucleotide insertion in vanY
