Loss of membrane‐bound lytic transglycosylases increases outer membrane permeability and β‐lactam sensitivity in Pseudomonas aeruginosa
The opportunistic pathogen Pseudomonas aeruginosa is a leading cause of nosocomial infections. Its relatively impermeable outer membrane (OM) limits antibiotic entry, and a chromosomally encoded AmpC β-lactamase inactivates β-lactam antibiotics. AmpC expression is linked to peptidoglycan (PG) recycling, and soluble (sLT) or membrane-bound (mLT) lytic transglycosylases are responsible for genera...
متن کاملPseudomonas aeruginosa outer membrane: peptidoglycan-associated proteins.
The Pseudomonas aeruginosa outer membrane was isolated with attached peptidoglycan and fractionated with Triton X-100, ethylenediaminetetraacetate, and lysozyme. The data suggest that major outer membrane proteins F, H2, and I are noncovalently associated with the peptidoglycan.
متن کاملMolecular Investigation of Outer Membrane Channel Genes Among Multidrug Resistance Clinical Pseudomonas Aeruginosa Isolates
Background: Multidrug resistance Pseudomonas aeruginosa (MDRPA) is most important issue in healthcare setting. It can secrete many virulence effector proteins via its secretion system type (T1SS-T6SS). They are using them as conductor for delivering the effector proteins outside to begins harmful effect on host cell increasing pathogenicity, competition against other microorganism and nutrient ...
متن کاملPseudomonas aeruginosa outer membrane permeability: isolation of a porin protein F-deficient mutant.
A mutant of Pseudomonas aeruginosa severely deficient in outer membrane protein F levels was isolated by screening heavily mutagenized strains for membrane protein alterations on sodium dodecyl sulphate-polyacrylamide gel electrophoresis. To provide a basis for phenotypic comparison, three independent spontaneous revertants with normal protein F levels were isolated. Neither the protein F-defic...
متن کاملOuter membrane permeability in Pseudomonas aeruginosa: comparison of a wild-type with an antibiotic-supersusceptible mutant.
The Pseudomonas aeruginosa mutant Z61 has been shown to be highly supersusceptible to a wide range of antibiotics, including beta-lactams, aminoglycosides, rifampin, tetracycline, and chloramphenicol (W. Zimmerman, Int. J. Clin. Pharmacol. Biopharm. 17:131-134, 1979). Spontaneous revertants were isolated, using gentamicin or carbenicillin as selective agents, and shown to have two patterns of s...
