Abstract: Shigella is the main pathogen of infectious diarrhea. In recent years, with the abuse of beta-lactam antibiotics, Shigella drug resistance has increased year by year. In addition, it shows the multi-drug resistance and cross-resistance. The resistance mechanisms is complex since it produces inactivated enzyme, changes action target and membrane permeability, and so on. Resistance genes are located in the plasmid, chromosome or transposable element, so it is easy to get spread. The study of resistance mechanism has a guiding significance for controlling the diseases caused by Shigella and new drug development.
