Abstract:
The spread of antibiotic resistance genes(ARGs)poses a serious threat to global public health.Recent studies have shown that in addition to the difficulty in antibiotic selection,many non-anti-biotic environmental pollutants,such as microplastics,heavy metals,nanomaterials and non-antibiotic drugs,can accelerate the spread of ARGs.This paper begins by outlining the influence of non-antibiotic environmental pollutants on the conjugative transfer of ARGs.Then,the mechanisms of ARGs are analyzed from the perspective of molecular biology,which include inducing the generation of large amounts of reactive oxygen radicals,triggering cellular oxidative stress,increasing intercellular contact,altering the permeability of cell membranes,affecting energy metabolism,triggering group sensing effects,and regulating the expression of genes related to the transfer of ARGs.Finally,the limitations of current studies are presented,and tips are given about future research.In conclusion,the effects of non-antibi-otic environmental pollutants on the spread and dispersal of ARGs need to be studied more extensively.
