Project description:Campylobacter jejuni is a common cause of diarrheal disease worldwide. Human infection typically occurs through the ingestion of contaminated poultry products. We previously demonstrated that an attenuated Escherichia coli live vaccine strain expressing the C. jejuni N-glycan on its surface reduces the Campylobacter load in more than 50% of vaccinated leghorn and broiler birds to undetectable levels (responder birds), whereas the remainder of the animals were still colonized (non-responders). To understand the underlying mechanism, we conducted 3 larger scale vaccination and challenge studies using 135 broiler birds and found a similar responder/non responder effect. The submitted data were used for a genome-wide association study of the chicken responses to glycoconjugate vaccination against Campylobacter jejuni.

Project description:Campylobacter jejuni is a human pathogen which causes campylobacteriosis, one of the most widespread zoonotic enteric diseases worldwide. Most cases of sporadic C. jejuni infection occur through the handling or consumption of undercooked chicken meat, or cross-contamination of other foods with raw poultry fluid. A common practice to combat Campylobacter infection is to treat chickens with chlorine which kills the microbe. This analysis aimed to elucidate the transcriptomic response of Campylobacter jejuni treated with hypochlorite through Illumina sequencing. C. jejuni was grown and treated with hypochlorite. Samples were taken 5, 20 and 45 min after treatment for RNAseq analysis.The data generated were compared to the transcriptome pre-exposure to determine C. jejuni's response to hypochlorite.

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:Campylobacter spp. cause food-borne illnesses worldwide due to contaminated food and cross-contamination. This is at least partly the result of Campylobacter resistance in the food production chain, as modern food production facilitates the emergence and spread of resistance through intensive use of antimicrobials and international trade in raw materials and food products. The biofilm 'lifestyle' of Campylobacter contributes to this spread as it enables them to withstand stress in the environment both outside and inside the host. Campylobacter adhesion and biofilm formation has major implications for the food industry, where biofilms can be persistent sources of contamination. In our study, we described how the proteome of C. jejuni is affected by the deletion of the luxS gene on the planktonic cell type of C. jejuni, which is the first step of biofilm formation. In C. jejuni, the presence of the luxS gene has been associated with several phenotypes, including intercellular signalling, motility, biofilm formation, host colonisation, virulence, autoagglutination, cellular adherence and invasion, oxidative stress and chemotaxis. Deletion of the luxS gene is associated with a reduction or absence of the above properties compared to wild type (Elvers and Park, 2002; Guerry et al., 2006; He et al., 2008; Jeon et al., 2003; Quiñones et al., 2009; Plummer et al., 2011; Plummer, 2012; Reeser et al., 2007).

The design utilized an available two color microarray slide for the entire transcriptome of Campylobacter jejuni. Four hybridizations were performed each with independently extracted samples of either macrolide susceptible ATCC 700819 cDNA samples or its isogenic Eryr transformant T.L.101 cDNA samples. A dye swap was utilized to help minimize dye dependent bias. Thus, there were four biological replicates of each sample.
