Thesis Abstract

Abstract
The emergence of multidrug-resistant bacteria poses a significant threat to public health worldwide, as it limits the effectiveness of conventional antibiotics. In response to this challenge, the present study aimed to investigate the antimicrobial potential of natural compounds against multidrug-resistant bacteria. The research involved the screening of various natural compounds for their antimicrobial activity against a panel of multidrug-resistant bacterial strains, including both Gram-positive and Gram-negative bacteria. The study utilized a combination of in vitro assays to evaluate the antibacterial efficacy of the natural compounds, along with mechanisms of action studies to elucidate their mode of action. The literature review section provided a comprehensive overview of the current state of antibiotic resistance, the mechanisms underlying multidrug resistance in bacteria, and the potential of natural compounds as alternative antimicrobial agents. The review highlighted the urgent need for novel antimicrobial strategies to combat multidrug-resistant bacteria and the promising role of natural compounds in this context. The research methodology section outlined the experimental design, including the selection of bacterial strains, the preparation and testing of natural compounds, and the methods used for antimicrobial activity assays and mechanistic studies. The study employed a combination of techniques, such as agar diffusion assay, broth microdilution assay, and scanning electron microscopy, to assess the antimicrobial efficacy of the natural compounds and investigate their effects on bacterial cell morphology. The results of the study revealed that several natural compounds exhibited potent antimicrobial activity against multidrug-resistant bacteria, with some compounds showing broad-spectrum activity against both Gram-positive and Gram-negative strains. Mechanistic studies indicated that the natural compounds exerted their antimicrobial effects through various mechanisms, including disruption of bacterial cell membrane integrity and inhibition of essential metabolic pathways. The discussion of findings section provided a detailed analysis of the results, highlighting the significance of the antimicrobial potential of natural compounds in combating multidrug-resistant bacteria. The findings of the study underscored the importance of exploring natural compounds as alternative antimicrobial agents and the need for further research to elucidate their full therapeutic potential. In conclusion, the study demonstrated the promising antimicrobial potential of natural compounds against multidrug-resistant bacteria, providing valuable insights into the development of novel antimicrobial strategies. The findings of the study contribute to the growing body of knowledge on alternative antimicrobial agents and have implications for the future treatment of multidrug-resistant bacterial infections.
