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.
使用联合疗法治疗严重耐甲氧西林金黄色葡萄球菌(MRSA)感染的证据越来越多。在本研究中,我们在时间杀菌实验中研究了达托霉素(DAP)与哌拉西林 - 他唑巴坦以及氨苄西林 - 舒巴坦联合对MRSA的协同作用。8株菌株中有6株显示DAP与β-内酰胺 - β-内酰胺酶抑制剂(BLI)组合之间存在协同作用。在8株菌株中的5株中,协同作用仅在BLI存在时发生,突出了BLI在肽 - β-内酰胺协同作用中的作用。
