a
Number of different clones cultured from a single patient as determined by PFGE.
b
agr groups of the different clones from a single patient (with different or the same agr groups, as indicated by the superscript number).
c
agr group of a clone that replaced another clone.
d
The different persistent strains were isolated independently (after a time break of more than 1 year, during which no S. aureus strain was isolated or the different strains were cultured in parallel or consecutively without replacement of a strain).
