Bacterial strains
Twenty-seven clinical isolates of S. aureus as well as the reference
strain S. aureus NCTC 8325-4 were used in this study. All
clinical strains were isolated at the Institute of Medical Microbiology,
University Hospital of Jena, Jena, Germany. The strains
were isolated from the following locations: upper respiratory tract
(n = 5); lower respiratory tract (n = 6); superficial wound infections
(n = 9); deep wound infections, e.g. bone (n = 5); and urinary tract
infections (n = 2). Two-thirds of them were penicillin-resistant and
additionally two strains were MRSA.
