Project description:Campylobacter jejuni has become the predominant cause of sheep abortions in the U.S. However, little is know about the genetic diversity among the isolates collected from different time periods. In this study, the genetic diversity of sheep aborion isolates of C. jejuni was investigated by Array-based CGH

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. Keywords: individual hybridizations, comparative genomic hybridization

Project description:Campylobacter jejuni is the leading cause of campylobacteriosis in the developed world. Although most cases are caused by consumption of contaminated meat, a significant proportion is caused by consumption of contaminated water. Some C. jejuni isolates are better than others at surviving in water, which suggests that these strains are better adapted to transmission by water than others. The aim of this study is to investigate this phenomenon further. CFU counts and viability assays showed that strain 81116 survives better than strain 81-176 in a defined freshwater medium at 4°C. Comparative transcriptomic profiling using microarray revealed that these strains respond differently to water. This series presents the transcriptome of strain 81116 in water.

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.

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. In experiment 1, relative levels of protein expression of three isolates carryint the CJIE1 prophage were compared with one lacking the prophage after growth on Mueller-Hinton agar containing blood. 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. Therefore experiment 2 was done (previous submission) to evaluate in a single 4-plex iTRAQ experiment the effect of sodium deoxycholate on protein expression and whether the presence of the CJIE1 prophage had any effect. The third set of experiments (experiment 3) was done to consolidate the previous observations into a single experiment for a single strain. In three replicate experiments C. jejuni isolate 00-2425 was grown on Mueller Hinton (MH) agar base, MH agar + 10% blood, MH agar containing 0.1% sodium deoxycholate and, to further investigate the nature and extent of the bile response, MH agar containing 2.5% Oxgall.
