Application of metagenomics in bacterial resistance in cattle production

Microorganisms are widely found in nature, mostly in soil and water. For ruminant animals, microorganisms make up a high percentage of their rumen. In recent years, the inappropriate use of antibiotics has led to a gradual increase in the resistance of bacteria commonly found in the bovine digestive tract which can be transmitted between humans, animals, and the environment. With the rapid development of molecular biology technology, Metagenomics technology can be more efficient, fast, and accurate in detecting resistance genes in samples and discovering novel resistance genes, making the study of bovine bacterial resistance more convenient and thorough. This paper mainly reviews bacterial resistance in cattle and the application of Metagenomics technology in this study. It intends to provide a theoretical reference for understanding the clinical application of metagenomics in bovine production to slow the emergence of bacterial resistance.
