Abstract
Two new genes (mexXY) similar to mexAB, mexCD, and mexEF and mediating mult idrug resistance were cloned from the chromosome of Pseudomonas aeruginosa. Elevated ethidium extrusion was observed with Escherichia coli cells harbo ring the plasmid carrying mexXY. This MexXY system confers higher resistanc e to fluoroquinolones than the MexAB and MexCD systems, and E. coli TolC or P. aeruginosa OprM is necessary for the function of the MexXY system.
