Item Current Status and Future Perspectives of Antibiotic Therapy for MRSA Infections(Preprints, 2023) Hajhamed, Nooh Mohamed; Abdalla, Abualgasim Elgaili; Mohammed, Salahdeen Ismail; Ahmed, Abdallah Elssir; Bakheit, Abdullah M.; Abdelbagi, Abubakar; Ali, Mohamed Sir Elkhatim; Omer, Rihab Ali; Siddig, Emmanuel Edwar; Ahmed, Ayman; Mohamed, Nouh SaadStaphylococcus aureus (S. aureus), particularly Methicillin-resistant S. aureus (MRSA), is a life threatening pathogen that causes a variety of infections in hospital and community settings. It poses a significant risk and challenge for global health that hinders our ability to control and treat bacterial infections. Recently, the emergence and spread of variant strains of bacteria, misuse of the limited available options of effective antibiotics, spread of fake drugs, and climate change that increased the contact between humans and animals’ populations carrying different bacterial has significantly increased the incidence of Multi-Drug Resistance strains (MDR). This in turn, has created a severe problem in the infection control treatment of S. aureus infected patients. Treatment options for MRSA infection are increasingly limited and complicated. Unfortunately, different strains of MRSA are showing tolerance and resistance toward vancomycin, which is the standard of care for complicated MRSA. Therefore, it is crucial now to invest developing new effective antibiotics and synergies, develop and implement national action plans for the management of antibiotic resistance, as well as improving our understanding of the antimicrobial resistance mechanisms. Here, in this review we explain the main mechanisms of antibiotic resistance in MRSA and describes different approaches to manipulate it in MRSA, providing a basis for designing effective drugs, and shedding some light on the evolution of S. aureus.
