Abstract

Purpose: Staphylococcus epidermidis has become one of the most common causes of septicemia. Meanwhile, S. epidermidis has acquired resistance to many antibiotics. Among these, methicillin-resistant S. epidermidis (MRSE) were frequently isolated. Similar to methicillin resistant Staphylococcus aureus (MRSA), they also exhibited multi-resistance, which presented a danger to human health. Patrinia scabiosaefolia as traditional Chinese medicine had strong antibacterial activity against MRSE. However, the mechanism of P. scabiosaefolia against MRSE is not clear.

Methods: Here, the morphology of cell wall and cell membrane, production of β-lactamase and PBP2, energy metabolism, antioxidant system were systematically studied.

Results: The data showed that P. scabiosaefolia damaged the cell wall and membrane. In addition, β-lactamase, energy metabolism and antioxidant system were involved in mechanisms of P. scabiosaefolia against MRSE.

Conclusion: These observations provided new understanding of P. scabiosaefolia against MRSE to control MRSE infections.

Keywords: Patrinia scabiosifolia; antioxidant system; energy metabolism; methicillin-resistantStaphylococcus epidermidis; β-lactamase.
