When grown in divalent cation-limited medium, Pseudomonas aeruginosa becomes
resistant to cationic antimicrobial peptides and polymyxin B. This resistance is regulated by …

The two‐component regulatory system PhoP‐PhoQ of Pseudomonas aeruginosa regulates
resistance to cationic antimicrobial peptides, polymyxin B and aminoglycosides in response …

Rapid adaptation to environmental challenge is essential for the survival of many bacterial
species, and is often effectively mediated by two‐component regulatory systems. Part of the …

Resistance to the polycationic antibiotic polymyxin B and expression of the outer-membrane
protein OprH in the opportunistic pathogen Pseudomonas aeruginosa both involve the PhoP …

Pseudomonas aeruginosa, a gram-negative bacterium of human pathogens, is noted for its
environmental versatility, enormous metabolic capacity, and resistance to antibiotics …

The PmrA-PmrB two-component system of Salmonella typhimurium controls resistance to
the peptide antibiotic polymyxin B and to several antimicrobial proteins from human …

Transcription profile microarray analysis in Escherichia coli was performed to identify the
member genes of the Mg2+ stimulon that respond to the availability of external Mg2+ in a …

ABSTRACT The PhoP/PhoQ two-component system controls several physiological and
virulence functions in Salmonella enterica. This system is activated by low Mg2+, acidic pH …

The PhoQ/PhoP signaling system responds to low magnesium and the presence of certain
cationic antimicrobial peptides. It regulates genes important for growth under these …

As multidrug resistance increases alarmingly, polymyxin B and colistin are increasingly
being used in the clinic to treat serious Pseudomonas aeruginosa infections. In this …
