(Submitter supplied) Purpose of study was to investigate whole genome expression changes of a strain with deletion of the two-component system TctD-TctE and determine genes dysregulate relative to the parental wildtype to gain insight into possible regulatory targets of TctD-TctE. TctD-TctE is a two-component system in Pseudomonas aeruginosa that responds to and regulates uptake of tricarboxylic acids such as citric acid. more...

(Submitter supplied) SbrI and SbrR are an extracytoplasmic function sigma factor and its cognate anti-sigma factor, respectively. To identify the SbrIR regulon, we measured gene expression in wild type PAO1 , PAO1 ∆sbrR, and PAO1 ∆sbrIR mutants using microarrays.

(Submitter supplied) Intercellular signal indole and its derivative hydroxyindoles inhibit Escherichia coli biofilm and diminish Pseudomonas aeruginosa virulence. However, indole and bacterial indole derivatives were unstable in microbial community due to the widespread of diverse oxygenases that could quickly degrade them. Hence, we sought to identify novel non-toxic, stable, and potent indole derivatives from plant sources for inhibiting biofilm formation of E. more...

(Submitter supplied) For the microarray experiments, 10 g glass wool (Corning Glass Works, Corning, N.Y.) were used to form biofilms (30) in 250 mL in 1 L Erlenmeyer shake flasks which were inoculated with overnight cultures diluted that were 1:100. For EHEC with 7-hydroxyindole and isatin, 1000 mM 7-hydroxyindole in 250 mL DMF, 250 mM isatin in 250 mL DMF, or 250 mL DMF alone were added to cells grown in LB. The cells were shaken at 250 rpm and 30°C for 7 hours to form biofilms on the glass wool, and RNA was isolated from the suspension cells and the biofilm. more...

Analysis of enterohemorrhagic Escherichia coli biofilm treated with 7-hydroxyindole or oxidized indole (isatin). Many bacterial oxygenases readily convert indole, an interspecies biofilm signal, into oxidized compounds. Results provide insight into the role of oxidized indoles in biofilm formation.
