Abstract [en]

In the present study, we have investigated 37 invasive Staphylococcus aureus strains (collected between 1997 and 2005) from 33 human episodes of septicaemia causing either endocarditis or vertebral osteomyelitis. All S. aureus strains were typed using pulsed field gel electrophoresis (PFGE), and most strains belonged to any of 4 different PFGE clusters. There was no correlation between any of the PFGE clusters with site of infection. All strains showed highly different expression patterns of extracellular proteins, i.e. we found a vast variation in the number of proteins and amount of individual proteins expressed by the different strains. There was no correlation between any cluster of exoprotein patterns with endocarditis or with vertebral osteomyelitis. We did not find any correlation between agr group and endocarditis, as previously reported. On the other hand, a correlation between some of the PFGE clusters with a certain agr group was found. Known risk factors for S. aureus infections were observed in a majority of the patients.
