Epigallocatechin gallate synergy with ampicillin/sulbactam against 28 clinical isolates of methicillin-resistant Staphylococcus aureus.
Compared with ampicillin, oxacillin, cefmetazole and imipenem, the combination of ampicillin and sulbactam at a constant ratio of 2:1 showed the greatest effect against 28 clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA), but MICs of ampicillin/sulbactam were still above the resistance breakpoint. When ampicillin/sulbactam was further combined with epigallocatechin gallat...
متن کاملSynergy of daptomycin with oxacillin and other beta-lactams against methicillin-resistant Staphylococcus aureus.
We previously observed marked synergy between daptomycin and both rifampin and ampicillin against vancomycin-resistant enterococci (VRE). Because the synergy between daptomycin and ampicillin was observed for 100% of VRE strains with high-level ampicillin resistance (ampicillin MIC of > or =128 microg/ml), we looked for synergy between daptomycin and other beta-lactams against 18 strains of met...

متن کاملIn-vitro and In-vivo Evaluation of Silymarin Nanoliposomes against Isolated Methicillin-resistant Staphylococcus aureus
Staphylococcus aureus is an opportunistic pathogen and remains a common cause of burn wound infections. Different studies have shown that entrapment of plant-derived compounds into liposomes could increase their anti-Staphylococcus aureus activity. Silymarin is the bioactive extract from the known plant Silybum marianum L. The objective of this study was to evaluate efficacy of silymarin in fre...
متن کاملMethicillin Resistant Staphylococcus aureus
Etiology Staphylococcus aureus is a Gram positive, coagulase positive coccus in the family Staphylococcaceae. Methicillin-resistant S. aureus (MRSA) strains are resistant to methicillin and essentially all other beta-lactam antibiotics. MRSA isolates are genetically heterogeneous. 1 Some strains, which are called epidemic strains; are more prevalent and can spread within or between hospitals an...
