Project Abstract

This project aims to investigate the antimicrobial properties of selected medicinal plants against pathogenic bacteria commonly found in livestock. The rise of antibiotic-resistant bacteria has become a pressing global issue, posing significant challenges to the health and productivity of livestock industries. Exploring alternative, natural antimicrobial sources, such as medicinal plants, is essential to develop sustainable and effective solutions to combat these resistant pathogens. Livestock play a crucial role in food production, economic development, and the livelihoods of millions of people worldwide. However, the emergence and spread of multidrug-resistant bacteria in livestock operations have led to increased morbidity, mortality, and economic losses for farmers and producers. Conventional antibiotic treatments are becoming less effective, necessitating the exploration of novel antimicrobial agents that can address this growing concern. Medicinal plants have long been used in traditional medicine for their therapeutic properties, including their antimicrobial activities. These natural compounds often exhibit diverse mechanisms of action, making them less susceptible to the development of resistance compared to synthetic antibiotics. By evaluating the antimicrobial potential of selected medicinal plants against pathogenic bacteria in livestock, this project aims to provide valuable insights into alternative treatment options and contribute to the development of sustainable, eco-friendly, and cost-effective strategies for livestock health management. The project will involve the following key components 1. Selection of Medicinal Plants Based on a comprehensive literature review and ethnobotanical surveys, a diverse range of medicinal plants with reported antimicrobial properties will be selected for further investigation. 2. Extraction and Phytochemical Analysis The selected medicinal plants will be subjected to solvent extraction, and the resulting extracts will be characterized for their phytochemical composition using advanced analytical techniques, such as high-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS). 3. Antimicrobial Susceptibility Testing The antimicrobial activity of the plant extracts will be evaluated against a panel of pathogenic bacteria commonly associated with livestock diseases, such as Escherichia coli, Staphylococcus aureus, and Salmonella species. Standard in vitro antimicrobial assays, including the disk diffusion method and minimum inhibitory concentration (MIC) determination, will be employed to assess the efficacy of the plant extracts. 4. Mechanism of Action Studies The mechanisms by which the active plant extracts inhibit the growth of pathogenic bacteria will be investigated using various biochemical and molecular techniques, such as membrane permeability assays, enzyme inhibition studies, and gene expression analysis. 5. In vivo Evaluation The most promising plant extracts will be further evaluated for their efficacy and safety in animal models, simulating the conditions encountered in livestock farming. This step will provide valuable insights into the practical applications and potential for the development of phytotherapeutic interventions. The findings of this project will contribute to the scientific understanding of the antimicrobial potential of medicinal plants and their potential application in livestock health management. The results may lead to the development of novel phytomedicines, feed additives, or disinfectants that can be used as alternatives or complementary treatments to conventional antibiotics, promoting sustainable and environmentally friendly approaches to livestock production.
