The Characteristic of Virulence, Biofilm and Antibiotic Resistance of .

is an important gram-negative opportunistic pathogen that causes a variety of infectious diseases, including urinary tract infections, bacteremia, pneumonia, and liver abscesses. With the emergence of multidrug-resistant (MDR) and () strains, the rapid spread of these clinical strains in geography is particularly worrying. However, the detailed mechanisms of virulence and antibiotic resistance in are still not very clear. Therefore, studying and elucidating the pathogenic mechanisms and drug resistance mechanism of infection are important parts of current medical research. In this paper, we systematically summarized the virulence, biofilm, and antibiotic tolerance mechanisms of , and explored the application of whole genome sequencing and global proteomics, which will provide new clues for clinical treatment of .
