Transmission of Antibiotic Resistance Genes and Degradation of Antibiotics in Environment
The rapid development of livestock and poultry farming is accompanied by the massive use of antibiotics which are excreted through feces and urine because they cannot be completely metabolized.The accumulated antibiotics in feces and urine enter the environment in various ways,thus leading to problems as antibiotic residues and drug resistance.It poses potential threats to human and animal health and the ec-ological environment,so it is important to effectively remove antibiotics from the environment.However,the removal of antibiotics should not only focus on the degradation effect,but also on secondary pollution,degradation costs and other issues.This paper introduces the sources and transmission of antibiotics and resistance genes in the breeding environment,and highlights the existing methods,principles and charac-teristics of antibiotic degradation,including physical adsorption,advanced oxidation technology and bio-degradation.It also proposes suggestions on the current antibiotic contamination problems in order to pro-vide reference for efficient antibiotic degradation.
