Identification of the extracellular proteins of P. aeruginosa that are involved in toxicity and adsorbed by microporous carbon

ABSTRACT: Culture supernatant of P. aeruginosa with or without microporous carbon (MgOC150) was separated by SDS-PAGE. Two major bands (35kDa and 20kDa), whose intensities were remarkably lower in the bacteria grown with MgOC150, were excised and subjected to in-gel digestion and LC-MS/MS analysis.

Pseudomonas aeruginosa is one of the most common pathogens isolated in clinical settings and produces a wide range of extracellular molecules that contributes to the virulence. Chemotherapy options to prevent and treat P. aeruginosa infections are limited because this pathogen is highly and innately resistant to some classes of conventional drugs. Alternative methods to conquer P. aeruginosa, including multidrug resistant strains, are being investigated. This study showed th ...[more]

A Cystic Fibrosis Pseudomonas aeruginosa Isolate Specialised to Catabolise Nucleic Acids

Project description:Purpose: Pseudomonas aeruginosa is a major cause of morbidity and mortality in patients with cystic fibrosis (CF). We provide an insight to the DNA auxotrophy of P. aeruginosa PASS4 isolate. Better understanding of P. aeruginosa adaptations in the CF lung environment can have a great impact in the development of specialised treatment regimes aimed at the eradications of P. aeruginosa infections. Methods: P. aeruginosa strains PAO1 and PASS4 were grown in minimal medium with either L-Asparagine or DNA as a carbon source, in biological triplicates. RNA was extracted and sequenced on Illumina HiSeq 1000 platform. The sequence reads that passed quality filters were analyzed using EdgePro and DESeq packages, as well as the Rockhopper tool. Results: We mapped > 10 million paired sequence reads per sample to the genome of P. aeruginosa PAO1 and identified a total of 576 genes differentially expressed by PASS4 when grown in DNA (P value < 0.01, log2 fold-change 1< to < -1), with 322 genes upregulated and 254 genes downregulated. There were a total of 423 genes differentially expressed by PAO1 when grown in DNA (P value < 0.01, log2 fold-change 1< to <-1), with 359 genes upregulated and 64 genes downregulated . A total of 129 transcripts displayed similar expression patterns in both organisms, with 112 being upregulated and 17 down-regulated. Conclusions: Our study identified that P. aeruginosa PASS4 was a purine auxotroph. Purine auxotropy may represent a viable microbial strategy for adaptation to DNA rich environments such as the CF lung.

Project description:The present data set provides the first description of lysine succinylation and lysine acetylation in P. aeruginosa grown in 4 carbon sources using a two-dimensional immunoaffinity approach coupled with nanoliquid chromatography tandem mass spectrometry. A total of 1522 succinylated sites (612 proteins) and 1103 acetylated sites (522 proteins) were characterized.

Antibacterial activities of the algal bromophenol methylrhodomelol against Pseudomonas aeruginosa

Project description:Methylrhodomelol (1) is a bromophenol from the red alga Vertebrata lanosa (L.) T.A.Christensen that has been associated with antimicrobial properties. Aim of the current study was therefore, to assess the antimicrobial potential of this compound in more detail against the gram-negative pathogen Pseudomonas aeruginosa. 1 exerted weak bacteriostatic activity against different strains when grown in minimal medium, whereas other phenolics were inactive. In addition, 1 (35 and 10 µg/mL) markedly enhanced the susceptibility of multidrug resistant P. aeruginosa towards the aminoglycoside gentamicin, while it did not affect the viability of Vero kidney cells up to 100 µM. Finally, pyoverdine release was reduced in bacteria treated at sub-inhibitory concentration, but no effect on other virulence factors was observed. Transcriptome analysis of treated versus untreated P. aeruginosa indicated an interference of 1 with bacterial carbon and energy metabolism, which was corroborated by RT-qPCR and decreased ATP-levels in treated bacteria.

Pseudomonas aeruginosa LC-MS/MS

Project description:Pseudomonas aeruginosa is a major cause of morbidity and mortality in patients with cystic fibrosis (CF). The P. aeruginosa CF isolate PASS4 has reduced ability to catabolise various carbon sources however can grow on DNA as a sole carbon source but, with a higher biomass production than P. aeruginosa burns wound, laboratory strain PAO1. Therefore, proteomic profiling of PASS4 and PAO1 was conducted following growth on DNA as a sole carbon source. To compare the protein expression of P. aeruginosa strains PAO1 and PASS4 following growth in DNA, the amino acid, asparagine was used a control condition, as asparagine was one of the amino acids PASS4 could utilise.

Evolution of the quorum sensing regulon in cooperating populations of Pseudomonas aeruginosa

Project description:We used the AHL-degrading enzyme AiiA-lactonase to interrogate the evolution of the LasR-dependent QS regulon of P. aeruginosa in conditions where QS is required to obtain carbon and energy, and show that populations of P. aeruginosa adaptively reduced the size of their QS regulon over ~1000 generations.

Gene expression in AES-2 clonal isolates of Pseudomonas aeruginosa

Project description:Pseudomonas aeruginosa (P. aeruginosa) lung infection is a significant cause of mortality in patients with cystic fibrosis (CF). Most CF patients acquire unique P. aeruginosa strains from the environment; however clonal strains have been identified in CF communities in several countries. Two clonal strains infect 10% to 40% of patients in three CF clinics in mainland eastern Australia. The expression profiles of four planktonically-grown isolates of one Australian clonal strain (AES-2), and four non–clonal CF P. aeruginosa isolates were compared to each other and to the reference strain PAO1 using the Affymetrix P. aeruginosa PAO1 genome array, to gain insight into properties mediating the enhanced infectivity of AES-1. The isolates were subsequently grown as 3-day old biofilms and similarly extracted for RNA and compared as above. Data analysis was carried out using BIOCONDUCTOR software. Keywords: Comparative strain hybridization

Pseudmonas aeruginosa PAO1 wild-type cultured in MOPS Glycerol compared to MOPS Glycerol Hypoxia (restricted oxygen).

Project description:Pseudmonas aeruginosa PAO1 wild-type cultured in MOPS Glycerol compared to MOPS Glycerol Hypoxia (restricted oxygen). P. aeruginosa strain PAO1 was grown in 40 ml MOPS with glycerol as sole carbon source (triplicate), 37 °C with shaking (250 rpm) in baffled flasks (500 ml). For the restricted oxygen condition, P. aerugionosa was cultured in the same conditions, except non-baffled flasks were used, and the shaking speed was 80 rpm (gentle aggitation). A thin layer 10 ml of mineral oil was overlaid on top of these cultures to restrict oxygen transfer.
