TraDIS-Xpress analysis of colistin stress responses in Escherichia coli

ABSTRACT: In past, resistance mechanisms have been identified by analysis of resistant isolates or defined mutants. Recently, high-throughput transposon mutagenesis coupled with sequencing (TraDIS-Xpress) is another approach proving useful for elucidating the roles of genes involved in the overall cellular response to a particular stress. In this study, we used TraDIS-Xpress to determine the role played by genes following exposure to colistin stress. Approximately 10^7 cells from the mutant library were inoculated into LB broth at a range of doubling concentrations of colistin ( 0.25 x MIC, 0.5 x MIC, 1 x MIC, 2 X MIC). Experiments were performed with no induction, or with induction using 0.2 or 1 mM of Isopropyl β-D-1-thiogalactopyranoside (IPTG). All experiments were performed in duplicate.

TraDIS-Xpress finds mechanisms of action and synergies of a novel lipid IVA biosynthesis inhibitor

Project description:We used TraDIS-Xpress to determine the mechanism of action of a novel antimicrobial compound. We found that it inhibits lipid IVA biosynthesis in both Escherichia coli and Salmonella enterica serovar Typhimurium. We also were able to determine mechanisms of synergy with colistin, through ATP biosynthesis and the BasSR signalling system.

TraDIS-Xpress to determine E. coli response to Piperacillin and Tazobactam separately and in combination

Project description:Found how E. coli responds to the commonly prescribed antibiotic-inhibitor combination piperacillin and tazobactam, separately and in combination. TraDIS-Xpress was performed following the protocol outlined by Yasir et al 2020 Genome Research. The results suggest tazobactam triggers the activity of multidrug efflux systems that have been previously seen to confer clinical resistance to multiple classes of antibiotics.

Genome wide analysis of genes involved in efflux function and regulation within Escherichia coli and Salmonella enterica serovar Typhimurium

Project description:Expression of efflux pumps is a key feature of most cells which are resistant to multiple antibiotics. This study used TraDIS-Xpress, a genome wide transposon mutagenesis technology to identify genes in Escherichia coli and Salmonella Typhimurium involved in drug efflux and its regulation. We exposed mutant libraries to the canonical efflux substrate acriflavine in the presence and absence of the efflux inhibitor phenylalanine-arginine β-naphthylamide. Comparisons between conditions identified efflux specific and drug specific responses. Known efflux associated genes were easily identified including: AcrAB-TolC, MarA, RamA and SoxS confirming specificity of the response. Further genes encoding cell envelope maintenance enzymes and products involved with stringent response activation, DNA housekeeping, respiration and glutathione biosynthesis were also identified as affecting efflux activity in both species. We identified a conserved set of pathways crucial for efflux activity in these experimental conditions which expands the list of genes known to impact efflux efficacy.

Comparison of the genetic basis of biofilm formation between Salmonella Typhimurium and Escherichia coli

Project description:Most bacteria can form biofilms, which typically have a life cycle from cells initially attaching to a surface before aggregation and growth produces biomass and an extracellular matrix before finally cells disperse. To maximise fitness at each stage of this life cycle, and given the different events taking place within a biofilm, temporal regulation of gene expression is essential. We recently described the genes required for optimal fitness over time during biofilm formation in Escherichia coli using a massively parallel transposon mutagenesis approach called TraDIS-Xpress. We have now repeated this study in Salmonella enterica serovar Typhimurium to determine the similarities and differences in biofilm formation through time between these species. This work deepens understanding of the core requirements for biofilm formation in the Enterobacteriaceae whilst also identifying some genes with specialised roles in biofilm formation in each species.

Transposon sequencing of E. coli in planktonic culture and in biofilms to determine the essentiality of genes throughout the biofilm life cycle

Project description:Biofilms undergo a life cycle where cells attach to a surface, grow and produce a structured community before dispersing to seed biofilms in new environments. Progression through this life cycle requires controlled temporal gene expression to maximise fitness at each stage. Previous studies have focused on the essential genome for the formation of a mature biofilm, but here we present an insight into the genes involved at different stages of biofilm formation. We used TraDIS-Xpress (a massively parallel transposon mutagenesis using transposon-located promoters to assay expression of all genes in the genome) to determine how gene essentiality and expression affects the fitness of E. coli growing as a biofilm on glass beads after 12, 24 and 48 hours. An E. coli transposon mutant library of approximately 800,000 unique mutants was grown on glass beads, and a planktonic sample was taken alongside this at each time point to compare gene essentiality and expression at each time point.

Identification of Campylobacter jejuni and Campylobacter coli genes contributing to aerobic stress response using TraDIS analysis

Project description:The experiment aimed to find how Campylobacter responds to oxidative stress using hydrogen peroxide. This was done by using previously made TraDIS libraries (https://bmcmicrobiol.biomedcentral.com/articles/10.1186/s12866-023-02835-8) and putting them under oxidative stress. The strains used were C. jejuni 11168, C. coli 15-537360 and C. coli CCN182.

Aminocandin versus Aminocandin plus Colistin

Project description:We found that the antibiotic colistin acts synergistically with antifungals of the echinocandin class (e.g. aminocandin) on C. albicans cells. In order to elucidate the mode of action of colistin in fungi we performed microarray analysis of samples treated with only aminocandin (0.00125µg/ml) or treated with aminocandin (0.00125µg/ml) and colistin (5µg/ml). We compared: (A). untreated cells to cells treated with aminocandin only; (B). cells treated with aminocandin to cells treated with aminocandin and colistin (which is the focus of this experiment). By comparing those datasets it should be possible to identify genes differentially expressed in response to aminocandin and in response to both drugs. And subsequently to be able to interpret where in the cell colistin acts. (See related experiment in ArrayExpress: E-MEXP-3437 for comparison between untreated cells vs cells treated with aminocandin only.)
