The Potential of Medicinal Plants to Enhance Antimicrobial Resistance in Diarrheal Pathogens

The global rise of antimicrobial resistance (AMR), particularly among diarrheal pathogens, poses a severe public health threat, especially in developing regions where diarrheal diseases remain a leading cause of child mortality. Conventional antibiotics are increasingly losing efficacy against multi-drug resistant (MDR) strains of Escherichia coli, Vibrio cholerae, and Salmonella spp. This calls for alternative therapeutic interventions. Medicinal plants, long employed in traditional medicine, offer a promising, sustainable solution due to their diverse phytochemical profiles and antimicrobial potential. This paper explores the role of selected medicinal plants in enhancing the treatment of diarrheal diseases and inhibiting resistant microbial strains. Focusing on plants such as Acacia nilotica, Julbernardia paniculata, and Maerua angolensis, the study highlights their inhibitory effects on key diarrheagenic bacteria, supported by in vitro findings. Mechanistic insights into plant-based bioactives such as phenolics, terpenes, and flavonoids suggest these compounds interfere with microbial resistance pathways and membrane integrity. The paper concludes that integrating medicinal plant research into mainstream therapeutic frameworks could play a vital role in addressing AMR and improving diarrheal disease outcomes globally.
