1all isolates, which were cultured during the observation period
2all mucoid isolates during this period, in parenthesis the percentage of mucoid isolates compared to non-mucoid isolates
3in parenthesis, the percentage of the number of non-mucoid isolates with 5 bp deletion in comparison to the number of mucoid isolates with 5 bp deletion
4all investigated non-mucoid and mucoid S. aureus isolates revealed the same spa-type
5MLST analyses was only performed for one non-mucoid and mucoid S. aureus isolate of each patient. The same MLST was determined for the S. aureus isolates of every patient.
