Project description:Campylobacter jejuni is a widespread pathogen responsible for most of the food-borne gastrointestinal diseases in Europe. For pathogen control in the food industry, the use of natural antimicrobial molecules is a promising strategy to avoid antibiotic treatments. Isothiocyanates are natural antimicrobial compounds which also display anti-cancer activity. Several studies described the chemoprotective effect of isothiocyanates on eukaryotic cells, but the antimicrobial mechanism is still poorly understood. We investigated the early cellular response of C. jejuni to benzylisothiocyanate (BITC) by both transcriptomic and physiological (respirometry, ATP content measurements and isolations of aggregated proteins).

Project description:This study investigates the CsrA regulon of the food-borne pathogen Campylobacter jejuni. Direct RNA binding targets of CsrA in two strains of C. jejuni, NCTC11168 and 81-176, were determined using RIP-seq.

Project description:Campylobacter jejuni causes food- and water-borne gastroenteritis, and as such must survive passage through the stomach in order to reach the gastrointestinal tract. While little is known about how C. jejuni survives transit through the stomach, its low infectious dose suggests it is well equipped to sense and respond to acid shock. In this study, the transcriptional profile of C. jejuni NCTC 11168 was obtained after exposure to in vitro acid shock. Keywords: acid shock; in vitro study; time course

While little is known about how C. jejuni survives transit through the stomach, its low infectious dose suggests it is well equipped to sense and respond to acid shock. In this study, the transcriptional profile of C. jejuni NCTC 11168 was obtained after exposure to in in vivo (piglet stomach) acid shock. Keywords: acid shock; in vivo study; transit through the host stomach

Project description:In order to cause disease, the food- and water-borne pathogen Campylobacter jejuni must face the extreme acidity of the host stomach as well as cope with pH fluctuations in the intestine. In the present study, C. jejuni NCTC 11168 was grown under mild acidic conditions mimicking those encountered in the intestine. The resulting transcriptional profiles revealed how this bacterium fine-tunes gene expression in response to acid stress. This adaptation involves differential expression of respiratory pathways, induction of genes for phosphate transport and repression of energy generation and intermediary metabolism genes. Keywords: acid shock; dose response; transcriptional response to 3 mild-acidic pH growth conditions (pH6.5, pH 6.0 and pH5.0)

Project description:Campylobacter jejuni is a major zoonotic pathogen transmitted to humans via the food chain. C. jejuni is prevalent in chickens, a natural reservoir for this pathogenic organism. Due to the importance of macrolide antibiotics in clinical therapy of human campylobacteriosis, development of macrolide resistance in Campylobacter has become a concern for public health.To facilitate understanding the molecular basis associated with the fitness difference between Erys and Eryr Campylobacter, we compared the transcriptomes between ATCC 700819 and its isogenic Eryr transformant T.L.101 using DNA microarray.

Project description:The Gram-negative bacterium Campylobacter jejuni is a widespread food-borne pathogen. Knowing the proteins encoded by the bacterial pathogen and how their expression is regulated is essential to understand how it survives, colonizes, and causes diseases. The present study focusses on small proteins (≤ 50-100 amino acids) translated from small open reading frames (sORFs). These poorly annotated components of the genome show emerging roles in bacterial physiology and virulence. Here, the proteome of C. jejuni during exponential growth in a complex medium was analyzed with the proteogenomics workflow presented in Fuchs et al., 2021 with the special focus on small proteins . In combination with different Ribo-Seq approaches new insights into the coding potential of the genome of C. jejuni are provided.

Project description:This study investigates the RNA targets and cleavage sites of endogenous Cas9 in the food-borne pathogen Campylobacter jejuni. Direct RNA binding targets of Cas9 in C. jejuni strain NCTC11168 were determined using RIP-seq. The Cleavage sites were then predicted in the RNA targets by comparing total transcriptome data from WT and deletion (cas9, crRNA3, tracrRNA, CRISPR-tracrRNA) strains. PAMs for the CjeCas9 were enriched using the PAM-SCANR platform, which operates through a GFP reporter gene. Upon GFP (and thus functional PAM) enrichment, fluorescing cells were isolated using FACS and prepared plasmid DNA was amplified and prepared for sequencing.

We investigated the early cellular response of C. jejuni to benzylisothiocyanate (BITC) by both transcriptomic and physiological (respirometry, ATP content measurements and isolations of aggregated proteins). To characterize the transcriptomic early response to benzylisothiocyanate, C. jejuni NCTC11168 were grown in 100 ml flasks containing 25 ml of MEMM-NM-1 medium plus 20 mM sodium pyruvate. At mid-log phase, 2M-BM-5g/mL benzylisothiocyanate in ethanol, or the same volume of ethanol (control) was added to the flasks for 10 or 15 min prior to total RNA extraction and purification. Samples were then processed for microarray hybridization. Microarray data was acquired from two (10 minutes assay) or three (15 minutes assay) independent biological replicates and 6 to 9 technical replicates for each biological replicate (total number of measurement per gene = 42).
