ABSTRACTGiven that it is unlikely that randomized clinical trials will yield answers for treating the most challenging bacteremic infections caused by methicillin-resistant Staphylococcus aureus, clinicians, microbiologists, and pharmacists will have to cooperate to discover novel ways to select successful individualized antimicrobial therapy for these patients. An example of such a strategy was demonstrated in the identification and utilization of imipenem/cilastatin plus fosfomycin to treat a particularly recalcitrant MRSA bacteremia and spinal abscess.

ABSTRACT The evidence for using combination therapy for the treatment of serious methicillin-resistant Staphylococcus aureus (MRSA) infections is growing. In this study, we investigated the synergistic effect of daptomycin (DAP) combined with piperacillin-tazobactam and ampicillin-sulbactam against MRSA in time-kill experiments. Six of eight strains demonstrated synergy between DAP and the β-lactam–β-lactamase inhibitor (BLI) combination. In 5/8 strains, the synergy occurred only in the presence of the BLI, highlighting a role for BLIs in peptide–β-lactam synergy.

ABSTRACTPeriprosthetic infection remains a challenging clinical complication. We investigated the antibacterial properties of pure (99.9%) magnesium (Mg)in vitroand in anin vivorat model of implant-related infection. Mg was highly effective against methicillin-resistantStaphylococcus aureus-induced osteomyelitis and improved new peri-implant bone formation. BacterialicaAandagrRNAIII transcription levels were also assessed to characterize the mechanism underlying the antibacterial properties of the Mg implant.
