The changes in lifestyle and living conditions have affected not only humans but also microorganisms. As man invents new drugs and therapies, pathogens alter themselves to survive and thrive. Multiple drug resistance (MDR) is the talk of the town for decades now. Many generations of medications have been termed useless as MDR rises among the infectious population. The surge in nanotechnology has brought a new hope in reducing this aspect of resistance in pathogens. It has been observed in several laboratory-based studies that the use of nanoparticles had a synergistic effect on the antibiotic being administered to the pathogen; several resistant strains scummed to the stress created by the nanoparticles and became susceptible to the drug. The major cause of resistance to date is the efflux system, which makes the latest generation of antibiotics ineffective without reaching the target site. If species-specific nanomaterials are used to control the activity of efflux pumps, it could revolutionize the field of medicine and make the previous generation resistant medications active once again. Therefore, the current study was devised to assess and review nanoparticles' role on efflux systems and discuss how specialized particles can be designed towards an infectious host's particular drug ejection systems.
生活方式和生活条件的改变不仅影响了人类,也影响了微生物。随着人类发明新的药物和疗法,病原体为了生存和繁殖而自我改变。多重耐药性(MDR)已经成为人们谈论了几十年的话题。随着感染人群中 MDR 的上升,许多代的药物已经被认为是无效的。纳米技术的兴起为减少病原体耐药性方面带来了新的希望。在几项基于实验室的研究中观察到,纳米粒子的使用对给予病原体的抗生素具有协同作用;几种耐药菌株对纳米粒子产生的压力产生了抵抗力,并对药物变得敏感。迄今为止,耐药性的主要原因是外排系统,它使最新一代的抗生素在到达靶位之前无效。如果使用针对特定物种的纳米材料来控制外排泵的活性,它可能会彻底改变医学领域,并使上一代耐药药物再次发挥作用。因此,目前的研究旨在评估和审查纳米粒子对外排系统的作用,并讨论如何针对感染宿主的特定药物排出系统设计专门的粒子。
