Transcriptional profiles of Campylobacter jejuni NCTC 11168 to 4mg/L erythromycin treatment

Project description:Erythromycin is the drug of choice to treat campylobacteriosis, but resistance to this antibiotic is rising. The adaptive mechanisms employed by Campylobacter jejuni to erythromycin treatment remain unknown. The aim of this study is to determine the molecular basis underlying CampylobacterM-bM-^@M-^Ys immediate response to Ery treatment. The design utilized an available two color microarray slide for the entire transcriptome of Campylobacter jejuni wild type strain NCTC 11168. One hybridizations were performed: sham-treated NCTC 11168 v.s. lethal dose erythromycin treated NCTC 11168. Samples were independently grown and harvested. There were three biological replicates of each sample.

Transcriptional profiles of Campylobacter jejuni NCTC 11168 to 0.125mg/L erythromycin treatment

Project description:Erythromycin is the drug of choice to treat campylobacteriosis, but resistance to this antibiotic is rising. The adaptive mechanisms employed by Campylobacter jejuni to erythromycin treatment remain unknown. The aim of this study is to determine the molecular basis underlying CampylobacterM-bM-^@M-^Ys immediate response to Ery treatment. The design utilized an available two color microarray slide for the entire transcriptome of Campylobacter jejuni wild type strain NCTC 11168. One hybridizations were performed: sham-treated NCTC 11168 v.s. sub-lethal dose erythromycin treated NCTC 11168. Samples were independently grown and harvested. There were three biological replicates of each sample.

The transcriptome of erythromycin-resistant Campylobacter jejuni strain selected from NCTC 11168

Project description:Campylobacter, a major foodborne pathogen, is increasingly resistant to macrolide antibibotics. Previous findings suggested that development of macrolide resistance in Campylobacter requires a multi-step process, but the molecular mechanisms involved in the process are not known. In our study, erythromycin-resistant C. jejuni mutant (R) was selected in vitro by stepwise exposure of C. jejuni NCTC11168(S) to increasing concentrations of erythromycin.The resistant were subjected to microarray and the the global transcriptional profile was analyzed. In this series, DNA microarray was used to compare the gene expression profiles of the macrolide-resistant strain with its parent wild-type strain NCTC11168. A large number of gene showed significant changes in R. The up-regulated genes in the resistant strains are involved in miscellaneous periplasmic proteins, efflux protein and putative aminotransferase, while the majority of the down-regulated genes are involved in electron transport, lipoprotein, heat shock protein and unknown function proteins. The over-expression of efflux pump and periplasmic protein was involved in the development of resistance to macrolide in C. jejuni.

Identification of pH-specific protein expression responses by Campylobacter jejuni strain NCTC 11168

Project description:Campylobacter jejuni is one of the major causes of food-borne infections world-wide. The species is strictly host associated and tolerates mild levels of acidity and alkalinity. The ability to survive pH challenges is one of the key aspects of the ability of C. jejuni to survive in food, stomach transit and enables host gastrointestinal tract colonisation. In this study C. jejuni reference strain NCTC 11168 grown within its pH physiological normal growth range (pH 5.8, 7.0 and 8.0, = ~0.5 h-1) and exposed to pH 4.0 shock for 2 hours. Proteins extracted from biomass were quantified using a combined data dependent and independent acquisition label-free based approach with the aim to identify pH-dependent proteins that respond in a growth phase independent manner. It was discovered that gluconate 2-dehydrogenase GdhAB, NssR-regulated globins Cgb and Ctb, cupin domain protein Cj0761, cytochrome c protein CccC (Cj0037c), and phosphate-binding transporter protein PstB all show acidic pH dependent abundance increases but are not activated by sub-lethal acid shock. Glutamate synthase (GLtBD) and the MfrABC and NapAGL respiratory complexes were induced in cells grown at pH 8.0. The response to pH stress by C. jejuni is to bolster microaerobic respiration and at pH 8.0 this is assisted by accumulation of glutamate the conversion of which could bolster fumarate respiration. Global protein abundance reduction of proteins linked to growth and survival overalls aids cellular energy conservation thus preserving a similar growth rate.

Screening for novel immunogenic proteins of Campylobacter jejuni NCTC 11168

Project description:The screening of a cDNA derived expression library of Campylobacter jejuni NCTC 11168 expressed in E. coli using a fusion construct and specific HaloTag interaction to a modified surface is shown. 1536 different clones were screened including positive (hisJ, cjaA, peb1a) and negative (argC, pyrC, gapA) reference proteins. The goal of the screening was to identify potential novel immunogenic proteins from C. jejuni by selecting clones showing a high signal intensity in comparison to the known antigens used as positive markers. Afterwards, the most promising clones were sequenced to identify the gene and corresponding protein, and these proteins were then investigated further. Consequently, 22 novel immunogenic proteins could be identified.
