Proteomic approach to Pseudomonas aeruginosa adaptive resistance to benzalkonium chloride.
UNLABELLED This study aimed to assess the membrane modifications in Pseudomonas aeruginosa after continuous exposure to increasing doses of benzalkonium chloride (BC). Two different concentrations were used, 0.9 and 12.0mM. Proteomic investigations revealed that the range of the outer membrane proteome alterations following continuous exposure is very low, i.e. about 10% and BC concentration de...
متن کاملMechanism of resistance to benzalkonium chloride by Pseudomonas aeruginosa.
The mechanisms of resistance of Pseudomonas aeruginosa to benzalkonium chloride (BC) were studied. The effluence of cell components was observed in susceptible P. aeruginosa by electron microscopy, but resistant P. aeruginosa seemed to be undamaged. No marked changes in cell surface potential between Escherichia coli NIHJC-2 and a spheroplast strain were found. The contents of phospholipids (PL...
متن کاملAdaptive response of single and binary Pseudomonas aeruginosa and Escherichia coli biofilms to benzalkonium chloride.
The main goal of this work was to examine whether the continuous exposure of single and binary P. aeruginosa and E. coli biofilms to sub-lethal benzalkonium chloride (BC) doses can induce adaptive response of bacteria. Biofilms were formed during 24 h and then put continuously in contact with BC for more 5 days. The six-day-old adapted biofilms were then submitted to BC challenge, characterized...
متن کاملPseudomonas aeruginosa and a Proteomic Approach to Bacterial Pathogenesis
Pseudomonas aeruginosa is a Gram-negative bacterium that is ubiquitous in the environment and can cause a variety of diseases in compromised patients. The genome of P. aeruginosa strain PAO1 has been reported to contain 5570 potential proteins. The value of this genomic database is that new proteins can be recognized to use as diagnostic markers, novel drug targets, and to better understand the...
متن کاملResistance of Pseudomonas to quaternary ammonium compounds. I. Growth in benzalkonium chloride solution.
Resistant cells of Pseudomonas aeruginosa and a waterborne Pseudomonas sp. (strain Z-R) were able to multiply in nitrogen-free minimal salts solution containing various concentrations of commercially prepared, ammonium acetate-buffered benzalkonium chloride (CBC), a potent antimicrobial agent. As the CBC concentration increased, growth increased until a point was reached at which the extent of ...
