Development history and current applications of methods for detecting antibiotic resistance genes

Abstract:

The spread of antibiotic resistance has aroused global concern. The development of technologies for detecting antibiotic resistance genes (ARGs) is essential for curbing the migration and spread of ARGs from the environment to plants/animals and human populations. This paper describes the development timeline of existing nucleic acid detection technologies and their first applications to the detection of ARGs and summarizes their detection principles, advantages and disadvantages, and development potential. Furthermore, this paper prospects that isothermal amplification combined with CRISPR/Cas might be the core technology for the development of in-situ rapid detection methods. By reviewing the development history of each technology, this paper aims to give insights into the development and applications of technologies for detecting ARGs and provide technical support for the research and control of antibiotic resistance transmission.
