摘 要
随着畜禽养殖业的快速发展，传统抗生素的滥用导致耐药性问题日益严重，开发新型抗菌药物成为解决这一困境的关键。本研究旨在探索新型抗菌药物在畜禽疾病防治中的应用效果及其安全性。通过筛选多种具有潜在抗菌活性的天然产物和合成化合物，采用体外抑菌实验、动物模型感染试验以及临床应用观察相结合的方法，系统评估了新型抗菌药物对常见畜禽病原菌的抑制作用。结果显示，所选新型抗菌药物对金黄色葡萄球菌、大肠杆菌等主要致病菌表现出显著的抑制效果，且在治疗剂量下未见明显毒副作用。特别地，一种从植物中提取的活性成分显示出优于传统抗生素的广谱抗菌特性，并能有效降低耐药菌株的产生风险。本研究不仅为畜禽疾病防治提供了新的药物选择，也为应对抗生素耐药性问题提供了创新思路，对于保障畜牧业健康发展具有重要意义。

ABSTRACT
With the rapid development of livestock and poultry farming, the misuse of traditional antibiotics has led to increasingly severe antibiotic resistance issues. Developing novel antimicrobial agents is crucial for addressing this challenge. This study aims to investigate the efficacy and safety of new antimicrobial drugs in the prevention and treatment of diseases in livestock and poultry. By screening various natural products and synthetic compounds with potential antimicrobial activity, we systematically evaluated the inhibitory effects of these novel agents on common pathogenic bacteria through in vitro antibacterial assays, animal model infection experiments, and clinical observations. The results demonstrated that the selected novel antimicrobial agents exhibited significant inhibitory effects against major pathogens such as Staphylococcus aureus and Escherichia coli, with no apparent toxic side effects observed at therapeutic doses. Notably, an active compound extracted from plants showed superior broad-spectrum antibacterial properties compared to traditional antibiotics and effectively reduced the risk of generating resistant strains. This research not only provides new drug options for the prevention and treatment of livestock and poultry diseases but also offers innovative approaches to tackling antibiotic resistance, which is of great significance for ensuring the healthy development of the livestock industry.
