a
All MRSA strains contained the mecA gene, the S. aureus fragment, and PVL genes and were negative for LukM.
b
M, male; F, female; S, sibling.
c
MLST, multilocus sequence type.
d
Only genes, encoding the different toxins, which were positive in the PCR are shown.
e
Only a mecA band detected.
f
—, no toxins detected.
