Thesis Overview

The project titled "Investigation of the antimicrobial properties of natural plant extracts against pathogenic bacteria" aims to explore the potential of natural plant extracts as alternatives to traditional antibiotics in combating pathogenic bacteria. With the rise of antibiotic resistance posing a significant threat to public health, there is a growing need to discover new antimicrobial agents that are effective and sustainable. Natural plant extracts have long been known for their diverse bioactive compounds that exhibit antimicrobial properties, making them promising candidates for further investigation. The research will involve conducting a series of experiments to evaluate the antimicrobial efficacy of selected natural plant extracts against a panel of pathogenic bacteria commonly associated with human infections. The project will utilize various microbiological techniques to assess the inhibitory effects of the plant extracts on bacterial growth, including agar well diffusion assays, minimum inhibitory concentration (MIC) determination, and time-kill kinetics studies. Additionally, the potential synergistic effects of combining plant extracts with conventional antibiotics will also be investigated to determine if there is a complementary action that enhances antimicrobial activity. Furthermore, the project will delve into the mechanisms of action underlying the antimicrobial properties of the natural plant extracts. This will involve exploring the interaction between the bioactive compounds within the extracts and bacterial cells, elucidating how they disrupt essential cellular processes and inhibit bacterial growth. Understanding these mechanisms will provide valuable insights into the potential applications of plant extracts as antimicrobial agents and guide future research efforts in optimizing their effectiveness. Overall, the research overview highlights the significance of investigating natural plant extracts as a sustainable source of antimicrobial agents to address the global challenge of antibiotic resistance. By elucidating the antimicrobial properties of these plant extracts against pathogenic bacteria and unraveling their mechanisms of action, the project aims to contribute to the development of novel therapeutic strategies for combating infectious diseases and promoting public health.
