Staphylococcus epidermidis has emerged as the main causative agent for graft-related and nosocomial infections. Rampant use of antibiotics and biofilm formed by the organism results in poor penetration of the drug and further aggravates the antibiotic resistance, emphasizing an urgent need to explore alternative treatment modalities. Antimicrobial peptides (AMPs), produced as effector molecules of the innate immunity of living organisms, have therapeutic potential that can be used to inhibit the growth of microbes. In addition, the susceptibility of a microbe to become resistant to an AMP is relatively low. The AMPs are amphipathic peptides of 12-100 residues, which have broad-spectrum activity against microbes. There are scattered reports of AMPs listed against S. epidermidis and there is an urgent need to systematically study the AMPs. Various natural AMPs as well as synthetic peptides have been investigated against S. epidermidis. These peptides have been shown to inhibit both planktonic culture and S. epidermidis biofilm effectively. The multiple modes of action in killing the organism minimize the chances for the development of resistance. This review focused on various natural and synthetic peptides that demonstrate activity against S. epidermidis.
表皮葡萄球菌已成为与移植相关感染和医院感染的主要病原体。抗生素的大量使用以及该生物体形成的生物膜导致药物渗透不佳,并进一步加剧抗生素耐药性,这凸显了探索替代治疗方式的迫切需求。抗菌肽(AMPs)作为生物体固有免疫的效应分子产生,具有可用于抑制微生物生长的治疗潜力。此外,微生物对AMPs产生耐药性的可能性相对较低。AMPs是由12至100个氨基酸残基组成的两亲性肽,对微生物具有广谱活性。有关于针对表皮葡萄球菌列出的AMPs的零散报道,迫切需要对AMPs进行系统研究。已经针对表皮葡萄球菌研究了各种天然AMPs以及合成肽。这些肽已被证明能有效抑制浮游培养物和表皮葡萄球菌生物膜。杀死该生物体的多种作用方式使产生耐药性的机会降至最低。本综述重点关注了对表皮葡萄球菌具有活性的各种天然和合成肽。
