奶牛乳房炎的微生物多样性与精准治疗策略
摘 要
奶牛乳房炎是影响全球乳制品行业的重要疾病，其发病机制复杂，微生物多样性显著。本研究旨在通过高通量测序技术解析奶牛乳房炎病原微生物的群落结构，并探索基于微生物组学的精准治疗策略。研究选取了来自中国北方多个牧场的120头患有乳房炎的奶牛样本，采用16S rRNA基因测序和宏基因组学方法，系统分析了病原微生物的多样性和丰度。结果表明，乳房炎的主要致病菌包括金黄色葡萄球菌、链球菌和大肠杆菌等，且不同地区和季节的微生物群落结构存在显著差异。基于这些数据，我们开发了一种基于机器学习的预测模型，能够准确识别不同类型的乳房炎病原体，并推荐个性化的抗生素治疗方案。

MICROBIAL DIVERSITY AND PRECISION TREATMENT STRATEGIES FOR MASTITIS IN DAIRY COWS
ABSTRACT
Cow mastitis is an important disease affecting the global dairy industry, with a complex pathogenesis and remarkable microbial diversity. This study aims to resolve the community structure of pathogenic organisms of cow mastitis through high-throughput sequencing technology and to explore precision treatment strategies based on microbiome. A ples of 120 dairy cows with mastitis from several pastures in northern China were selected and systematically analyzed the diversity and abundance of pathogenic microorganisms using 16S rRNA gene sequencing and me tagenomics. The results showed that the main pathogenic bacteria of mastitis include Staphylococcus aureus, Streptococcus and E. coli, and the microbial community structure varied significantly in different regions and seasons. Based on these data, we developed a machine learning-based predictive model that enables accurate identification of different types of mastitis pathogens and recommended personalized antibiotic treatment options.
