Transcriptional profiles of NCTC11168 grown with or without 25mM fucose

ABSTRACT: Strain specific growth of C. jejuni on fucose has been linked to a plasticity region of the chromosome (PR2) and confers a competitive advantage during intestinal colonization. Growth on fucose induces gene expression of PR2 genes, but the regulatory mechanism of the structural genes involved with fucose utilization is unknown. Additionally, the mechanism of fucose dissimilation by C. jejuni is not known since no fucose catabolism homologs are found in the C. jejuni genome. Transcriptional profiles of C. jejuni grown with and without fucose may provide insight in to the genes that are necessary for fucose utilization. The design utilized an available two color microarray slide for the entire transcriptome of Campylobacter jejuni wild type strain NCTC 11168. Each sample represents one competitive hybridization: sham-treated NCTC 11168 v.s. 25mM fucose treated NCTC 11168. There were four biological replicates of each sample with a dye swap introduced in alternating replicates. Samples were independently grown, treated and harvested.

Transcriptional profiles of wild-type NCTC11168 and Cj0480c mutant grown without fucose

Project description:Strain specific growth of C. jejuni on fucose has been linked to a plasticity region of the chromosome (PR2) and confers a competitive advantage during intestinal colonization. Growth on fucose induces gene expression of PR2 genes, but the regulatory mechanism of the structural genes involved with fucose utilization is unknown. A mutant was constructed to examine the role of Cj0480c, a putative IclR-type transcriptional regulator, on PR2 gene expression. Transcriptional profiles of wild-type C. jejuni and the Cj0480c mutant strain grown without fucose may provide insight in to the extent of the fucose regulon and genes that are necessary for fucose utilization. The design utilized an available two color microarray slide for the entire transcriptome of Campylobacter jejuni wild type strain NCTC 11168. Each sample represents one competitive hybridization: wild-type NCTC 11168 v.s. Cj0480c isogenic mutant. There were four biological replicates of each sample with a dye swap introduced in alternating replicates. Samples were independently grown, treated and harvested.

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.

CGH analysis of Campylobacter jejuni isolates previously analyzed by Multi-Locus Sequence Typing

Project description:In this experiment, we hava analyzed a set of 45 C. jejuni strains by CGH and MLST in order to investigate whether the strain relationships inferred from the analysis of a small number of loci (MLST) reflect whole-genome gene conservation patterns observed by CGH. We performed microarray CGH on 45 strains previously characterized by MLST. Genomic DNA from each experimental strain was compared in a CGH experiment against the reference strain NCTC 11168. We measured signal intensity for each tester strain versus the control strain NCTC 11168. Values represent mean of replicate spots. Replicate arrays are not included.

The role of the Cj0440c gene in erythromycin-resistant (Eryr) Campylobacter jejuni

Project description:Cj0440c, a putative transcriptional regulator, was over-expressed in the high-level erythromycin-resistant (Eryr) Campylobacter jejuni strains. To determine the role of Cj0440c on the development and fitness of erythromycin resistance in C. jejuni, we knocked out Cj0440c in Eryr strain (R) to obtain the Cj0440c mutants (RM). Then we compared the transcriptome of the Cj0440c mutant with that of the parent strain using DNA microarray. These comparisons identified 9 genes that showed a M-bM-^IM-%2-fold change in expression in RM. The differentially expressed genes in RM are related to flagellar biosynthesis and unknown functions. What's more, katA, encoding catalase, down-regulated in RM. Cj0440c may progress flagellar genes expression, help to escape drug pressure and disseminate and colonize smoothly, and Cj0440c in Eryr Campylobacter may protect bacteria from harmful oxygen stress from the host immune system, other microorganism in host intestinal and its own products. These findings indicate that Cj0440c is essential for the fitness (growth) of resistant C. jejuni by controlling the expression of several genes involved in flagellar assembly and catalase, enhancing cell motility for colonization and invasion under the pressure of drug. This study widened our understanding on the molecular mechanism of resistance and provides scientific reference for drug research and application. An eight-chip study using total RNA recoverd from four separate resistant-type cultures of Erythrocin-resistant Campylobacter jejuni NCTC 111168 (R) and four separate cultures of a mutant strain, erythrocin-resistant Campylobacter jejuni NCTC 11168 delta- Cj0440c (RM), in which Cj0440c is deleted. Each chip measures the expression level of 1634 genes from Campylobacter jejuni NCTC 11168.
