Drug Resistance Mechanism and Detection Method of Salmonella

Abstract

As an important zoonotic food-borne pathogen, Salmonella is a concern for public health authorities. In particular, bacteria that are resistant to multiple antimicrobials can confuse the efficacy of treatment for infectious diseases. Drug-resistant bacteria have a variety of drug-resistant molecular and cellular mechanisms. These antimicrobial resistance mechanisms include antibiotic efflux, permeability changes in cell membranes, enzymatic drug inactivation, biofilm formation, drug target changes, and protection of antimicrobial targets. In this paper, the mechanisms of antimicrobial resistance in salmonella and the techniques of detecting antibiotic resistance by traditional and molecular methods are reviewed, with emphasis on their advantages and disadvantages, as well as the validity and reliability of the results.
