Project Abstract

This project aims to investigate the antimicrobial potential of indigenous plant extracts against multidrug-resistant (MDR) pathogens, which pose a significant threat to public health worldwide. The rise of antibiotic-resistant bacteria has become a global concern, as traditional antimicrobial treatments are becoming increasingly ineffective. This crisis has driven the need to explore alternative, natural sources of antimicrobial compounds, such as those found in indigenous plant species. The project will focus on the systematic screening and evaluation of various indigenous plant extracts for their ability to inhibit the growth of MDR bacteria, including Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae. These pathogens have developed resistance to multiple classes of antibiotics, making them challenging to treat in clinical settings. The research will employ a multifaceted approach, combining ethnobotanical knowledge, laboratory-based experiments, and advanced analytical techniques. Initially, the project will conduct an extensive literature review to identify promising indigenous plant species with reported antimicrobial properties. This information will guide the selection of plant samples for further investigation. The selected plant materials will be subjected to systematic extraction using various solvents, and the resulting extracts will be screened for their antimicrobial activity against the target MDR pathogens. The screening process will involve in vitro techniques, such as disc diffusion assays and minimum inhibitory concentration (MIC) determinations, to assess the inhibitory effects of the plant extracts on bacterial growth. To gain a deeper understanding of the antimicrobial mechanisms, the project will also investigate the phytochemical composition of the most promising plant extracts. Advanced analytical techniques, such as high-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS), will be employed to identify and quantify the active antimicrobial compounds present in the extracts. Furthermore, the project will explore the potential synergistic effects of combining plant extracts with conventional antibiotics. This approach aims to enhance the antimicrobial efficacy and potentially overcome the resistance mechanisms of the targeted MDR pathogens. The anticipated outcomes of this project are multifold. First, it will contribute to the identification of indigenous plant species with potent antimicrobial properties against MDR bacteria, which could lead to the development of new natural-based therapeutic alternatives. Second, the project will provide insights into the phytochemical composition and antimicrobial mechanisms of the most promising plant extracts, paving the way for further optimization and drug discovery efforts. Additionally, the findings of this research may have significant implications for public health, as the development of new antimicrobial agents can help address the global challenge of antibiotic resistance. By leveraging the rich biodiversity and traditional knowledge of indigenous plant species, this project aims to contribute to the ongoing efforts to combat the rise of MDR pathogens and improve human health.
