Abstract:

Antibiotics can not only control the bacterial disease of acquatic organisms, but also promote their growth. Therefore, it is widely used in aquaculture industry. Recently, China as a major worlds aquaculture country, her culture ecological environment is seriously suffering from the antibiotic pollution. Thus, a new type of environmental pollutant-antibiotic resistance gene is induced. Such pollutant can enter human body through horizontal gene transfer, and ultimately endanger human health. So it is attracting wide attention at home and abroad. On the basis of understanding the actual utilization of antibiotics in acquireculture environment, this paper explained the origin of antibiotic resistance gene, its action mechanism, spread diffusion mechanism, and the impacts of pollution hazards. The paper also forecasted the future research direction of antibiotic resistance gene, so as to arouse the attention of relevant researchers, and to provide basis for the protection of aquaculture environment and aquatic products quality and safety.
