Campylobacter jejuni transcriptional response during growth in media with low and high viscosity

ABSTRACT: Campylobacter jejuni normally grows in the lower intestinal mucus layer as a commensal in avian and animal hosts or as a pathogen in humans. Increasing viscosity of media to physiological levels present in lower intestinal mucus has been observed to increase growth and swimming velocity of WT C. jejuni. Two mutants (DflgV) and (DvidC; DCjj81176_1732) that lack components of the C. jejuni flagellar motor were identified that do not properly modulate swimming velocity in a viscosity-dependent manner. These mutants also have growth and viability defects when grown in standing broth cultures composed of Mueller-Hinton broth at low viscosity (1 cP; no methycellulose) or higher viscosity (40 cP; with methylcellulse). The transcriptome of WT C. jejuni and two mutants lacking FlgV or VidC were analyzed and compared after growth in standing Mueller-Hinton broth cultures of 1 or 40 cP.

Exposure of oxygen limited Campylobacter jejuni to 10 micromolar NOC-5 & NOC-7

Project description:Batch cultures of Wild-type C. jejuni NCTC 11168 were grown in 200 ml volumes of Mueller-Hinton broth in 250 ml baffled flasks. Microaerophilic conditions were generated using a MACS-VA500 microaerophilic work station (10 % Oxygen, 10 % Carbon dioxide, 80 % Nitrogen) from Don Whitley Scientific, Ltd which also maintained the growth temperature at 42 ºC. When mid-exponential phase was reached 0.010 mM NOC-5 & NOC-7 was added to one of the cultures. After a 15 minute exposure samples of both treated and untreated cells were harvested into phenol/ethanol to stabilize the RNA and total RNA was purified using Qiagen’s RNeasy Mini kit (as recommended by the suppliers) prior to use in microarray analysis.

Project description:Batch cultures of Wild-type C. jejuni NCTC11168 were grown in 150 ml volumes of Mueller-Hinton broth in 250 ml baffled flasks. Microaerophilic conditions were generated using a MACS-VA500 microaerophilic work station (10 % O2, 10 % CO2, 80 % N2) from Don Whitley Scientific, Ltd which also maintained the growth temperature at 42 ºC. When mid-exponential phase was reached 0.25 mM GSNO was added to half of the cultures.

Effects of Campylobacter jejuni CJIE1 prophage on protein expression experiment 2

Project description:Temperate bacteriophages (prophages) have recently been demonstrated in Campylobacter jejuni. However, what they do there is largely unknown. In the series of studies that are the subject of these submissions we have investigated the relative expression levels of proteins in C. jejuni isolates that differ in the presence or absence of the CJIE1 prophage. At the time of the initial investigations whole genome sequence data were not available for the isolates used, though DNA microarray data indicated that the isolates were very closely related. The overall project was carried out through four separate experiments. Previous work in the scientific literature indicated that growth on medium lacking blood but containing sodium deoxycholate induced the expression of at least some proteins associated with virulence and provided data thought to be of relevance to the virulence of the bacterium. The second set of experiments (experiment 2) therefore compared protein expression in 4-plex iTRAQ experiments using two isolates. Isolate 00-2425 carried the CJIE1 prophage while the second isolate, 00-2426, did not. Three replicate experiments were done. Each isolate was grown on Mueller Hinton agar base and Mueller Hinton agar containing 0.1% sodium deoxycholate.
