耐甲氧西林表皮葡萄金黄色葡萄球菌在近几十年中出现,成为世界范围内感染的主要原因。MRSA定植易感染并促进病原体的传播;然而,可用的方案在预防MRSA定植方面无效。对人类鼻腔植物群的研究表明,常驻细菌在限制S.金黄色葡萄球菌生长,并促使我们质疑应用鼻腔驻留细菌是否可以防止MRSA的鼻腔定植。我们建立了一种小鼠模型系统来研究这个问题,并表明小鼠鼻内预先定殖了S。表皮变得对MRSA定植更有抗性。我们的研究表明,应用抗生素的肠道细菌可能是一种更有效的策略,以防止MRSA定植。
Methicillin-resistant S. aureus emerged in recent decades to become a leading cause of infection worldwide. Colonization with MRSA predisposes to infection and facilitates transmission of the pathogen; however, available regimens are ineffective at preventing MRSA colonization. Studies of human nasal flora suggest that resident bacteria play a critical role in limiting S. aureus growth, and prompted us to query whether application of commensal resident bacteria could prevent nasal colonization with MRSA. We established a murine model system to study this question, and showed that mice nasally pre-colonized with S. epidermidis became more resistant to colonization with MRSA. Our study suggests that application of commensal bacteria with antibiotics could represent a more effective strategy to prevent MRSA colonization.
