Medicinal Remedies for the Treatment of Methicillin Resistant Staphylococcus Aureus

Abstract

Antimicrobial resistance has led to the rise of formidable microbes like methicillin-resistant Staphylococcus aureus (MRSA). This infection can be acquired at the hospital and in a community, making the search for efficient treatment critical, given the rise in inefficacy of conventional treatments such as vancomycin. Phytocompounds can offer protection against these threats. They not only have the ability to kill MRSA but also enhance its susceptibility to previously ineffective antimicrobial agents. Plant-derived anti-MRSA agents can produce therapeutic effects comparable to some conventional treatments, and in some cases, they may even outperform an antibiotic. This article provided many examples of botanical compounds that have proven potent agents against MRSA in both in vitro and in vivo studies. These compounds achieve these effects by inhibiting the resistance mechanisms in MRSA, breaking down its defenses, making it vulnerable, and eventually killing it. Many of these compounds are inherently bactericidal; however, they may produce a synergistic response when combined with allopathic antibiotics. For example, plumbagin, from Plumbago zeylanica, not only disrupts MRSA cell wall morphology, eliciting cytoplasmic changes but also produces a synergistic effect with ciprofloxacin and piperacillin. Moreover, honokiol and magnolol glycosides, from Magnolia officinalis, reversed the quintessential resistance of MRSA by repressing genes, responsible for resistance development.  The possibilities are indeed endless, but further research and financial investments are required for proper drug development.
