Article
Open AccessIn this work, we propose a novel methodology for electrical monitoring using nanoporous alumina membranes of virulence factors secreted by bacterial pathogens. Bacterial hyaluronidase (HYAL), which is produced by a number ... -
Enzyme multilayer coatings inhibit Pseudomonas aeruginosa biofilm formation on urinary catheters
(2015-01-15)
Article
Open AccessBacteria use a signaling mechanism called quorum sensing (QS) to form complex communities of surface-attached cells known as biofilms. This protective mode of growth allows them to resist antibiotic treatment and originates ... -
Escherichia coli and pseudomonas aeruginosa eradication by nano-penicillin G
(2016-06-09)
Article
Open AccessThe transformation of penicillin G into nano/micro-sized spheres (nanopenicillin) using sonochemical technology was explored as a novel tool for the eradication of Gram-negative bacteria and their biofilms. Known by its ... -
Immobilization of antimicrobial core-shell nanospheres onto silicone for prevention of Escherichia coli biofilm formation
(2016-09-16)
Article
Open AccessEscherichia coli (E. coli) strains are among the most frequently isolated microorganisms in urinary tract infections able to colonize the surface of urinary catheters and form biofilms. These biofilms are highly resistant ... -
Inhibition of quorum-sensing: A new paradigm in controlling bacterial virulence and biofilm formation
(Springer Nature, 2018-05-31)
Part of book or chapter of book
Restricted access - publisher's policyBacterial pathogens coordinate the expression of multiple virulence factors and formation of biofilms in cell density dependent manner, through a phenomenon named quorum sensing (QS). Protected in the biofilm community, ... -
