The prevalence, population structure and screening test specificity of penicillin-susceptible Staphylococcus aureus bacteremia isolates in Malmö, Sweden

Considering that intravenous penicillin has theoretical advantages compared with the standard treatment in the study area, we argue that routine testing of penicillin susceptibility should be reconsidered.
