This study reviews Staphylococcus aureus, a significant pathogen in both hospital and community-acquired infections, addressing its epidemiology, pathogenesis, and antimicrobial resistance. It highlights virulence mechanisms, such as adhesion factors, toxins, enzymes, and biofilms, which contribute to survival and immune evasion. The spread of resistance occurs through the transfer of mobile genetic elements like SCCmec and genetic mutations. The analysis also compares hospital and community strains, including multidrug-resistant lineages like MRSA, VISA, and VRSA. The study concludes that S. aureus presents a major public health challenge, requiring new therapeutic approaches and preventive strategies.
本研究回顾了金黄色葡萄球菌，它是医院感染和社区获得性感染中的一种重要病原体，探讨了其流行病学、发病机制和抗菌耐药性。它强调了毒力机制，如粘附因子、毒素、酶和生物膜，这些有助于其生存和逃避免疫。耐药性的传播通过移动遗传元件如SCCmec的转移和基因突变发生。分析还比较了医院菌株和社区菌株，包括耐多药谱系如MRSA、VISA和VRSA。该研究得出结论，金黄色葡萄球菌带来了重大的公共卫生挑战，需要新的治疗方法和预防策略。
