In this study, our findings provided at least three new mechanisms for translocation of Pseudomonas aeruginosa from the colonized gastrointestinal tract: (i) the pyoverdine synthesis gene (pvdE) facilitates penetration of P. aeruginosa through the epithelial cell barrier depending on regulating the expression of the exoS gene, impairs the defense function of tight junctions; (ii) P. aeruginosa can degrade interleukin-8 (IL-8) following the expression of the exoS and mucD gene; (iii) P. aeruginosa can penetrate the mucus layer using the flagellar motility and the mucin degradation. These results revealed that functions of P. aeruginosa can penetrate mucus layer and epithelial cells junction, which serve as important barriers in the intestinal epithelial tissue, and a survival strategy of P. aeruginosa to the host immune system.
