Investigating the Antimicrobial Properties of Herbal Extracts against Drug-Resistant Bacteria

Thesis Abstract

Abstract
The increasing prevalence of drug-resistant bacteria poses a significant threat to public health, emphasizing the urgent need for alternative antimicrobial agents. Herbal extracts have been recognized for their potential antimicrobial properties and are being explored as a possible solution to combat drug resistance. This thesis aims to investigate the antimicrobial properties of selected herbal extracts against drug-resistant bacteria. The study will focus on identifying specific herbal extracts with potent antimicrobial effects and elucidating their mechanisms of action.
