Quorum-sensing regulator sdiA and marA overexpression is involved in in vitro-selected multidrug resistance of Escherichia coli.
OBJECTIVES The role of sdiA in the acquisition of low-level multidrug resistance (MDR) was analysed and compared with that of marA and soxS in two Escherichia coli clinical isolates and two in vitro-selected mutants. METHODS The mutants were developed by growth in lomefloxacin and ceftazidime. The sdiA, marA, soxS, ftsI, tolC and acrB gene transcript levels were determined by RT-PCR. Analyses...
متن کاملQuorum sensing and multidrug transporters in Escherichia coli.
Previously, we found that the quorum sensing transcription factor SdiA up-regulates AcrAB. Others found that a 4-quinolone was a quorum-sensing signal in Pseudomonas aeruginosa. In Escherichia coli, there are at least three multidrug transporters (AcrAB/TolC, MdfA, and NorE) that exude fluoroquinolones. Here, we show that DeltaacrAB, tolC210, or DeltanorE mutants have the same growth rate as WT...
متن کاملMarA-like regulator of multidrug resistance in Yersinia pestis.
MarA47(Yp) from Yersinia pestis, showing 47% identity to Escherichia coli MarA in its N terminus, caused resistance to antibiotics and to organic solvents when expressed in both E. coli and Y. pestis. Resistance was linked to increased expression of the AcrAB multidrug efflux pump. In four of five spontaneous multidrug-resistant mutants of Y. pestis independently selected by growth on tetracycl...
متن کاملStructural insights into the molecular mechanism of Escherichia coli SdiA, a quorum-sensing receptor.
Escherichia coli SdiA is a quorum-sensing (QS) receptor that responds to autoinducers produced by other bacterial species to control cell division and virulence. Crystal structures reveal that E. coli SdiA, which is composed of an N-terminal ligand-binding domain and a C-terminal DNA-binding domain (DBD), forms a symmetrical dimer. Although each domain shows structural similarity to other QS re...
متن کاملOrganic solvent tolerance and antibiotic resistance increased by overexpression of marA in Escherichia coli.
We previously reported that overexpression of the soxS or robA gene causes in several Escherichia coli strains the acquisition of higher organic solvent tolerance and also increased resistance to a number of antibiotics (H. Nakajima, K. Kobayashi, M. Kobayashi, H. Asako, and R. Aono, Appl. Environ. Microbiol. 61:2302-2307, 1995). Most E. coli strains cannot grow in the presence of cyclohexane. ...
