Global transcriptional analysis of Campylobacter jejuni NCTC 11168 after inactivation of flagella biosynthesis regulator FlhF

(Submitter supplied) Campylobacter jejuni produces a single flagellum on one or both poles of the cell, the polar flagella not only confer the bacterium darting motility but also involved in its virulence and metabolic processes. FlhF is a lately defined flagella biosynthesis regulator, but how it regulates flagella assembly isn’t clear at present. Previous research had indicated FlhF was associated with gene expression, to understanding its role in flagella system and its correlation with C. more...

Transcriptomic analysis of Campylobacter jejuni grown in medium containing serine as a main energy source

(Submitter supplied) Campylobacter jejuni is one of the most important causes of food-borne diseases in industrialized countries. It is known that amino acids are important nutrient source for this pathogen, because C. jejuni lacks enzymes related to glycolysis. However, the characteristics on metabolism of C. jejuni grown in the nutrient restricted medium with a specific amino acid is not fully elucidated. This study shows that C. more...

The food-borne pathogen Campylobacter jejuni responds to the bile salt deoxycholate with countermeasures to reactive oxygen species

(Submitter supplied) Bile plays an important role in digestion, absorption of fats, and the excretion of waste products, while concurrently providing a critical barrier against colonization by harmful bacteria. Previous studies have demonstrated that gut pathogens react to bile by adapting their protein synthesis. The ability of pathogens to respond to bile is remarkably complex and still incompletely understood. Here we show that Campylobacter jejuni, a leading bacterial cause of human diarrheal illness worldwide, responds to deoxycholate, a component of bile, by altering global gene transcription in a manner consistent with a strategy to mitigate exposure to reactive oxygen stress. more...

Genome analysis of C. jejuni and C. coli isolated from different regions of the same chicken

(Submitter supplied) The gut of chicken is mostly colonised with Campylobacter jejuni and with 100 fold less C. coli. The competitive ability of C. coli OR12 over C. jejuni OR1 has been examined in experimental broiler chickens following the observation that C. coli replaced an established C. jejuni intestinal colonisation within commercial chicken flocks reared outdoors (El-Shibiny, A., Connerton, P.L., Connerton, I.F., 2005. more...

Transcriptomic analysis of C. jejuni HPC5 with C. jejuni HPC5 R14, R20, R14A, R14B, R20A, R20B and R20C.

(Submitter supplied) C. jejuni HPC5 is a Campylobacter strain isolated from chickens. Following bacteriophage CP34 treatment on chickens colonised by C. jejuni HPC5, a series of CP34 insensitive strains like C. jejuni HPC5 R14 and C. jejuni HPC5 R20 were obtained which compromised their ability to colonise chickens. Reintroduction of C. jejuni HPC5 R14 and R20 in to chickens led to reversion of these strains and the MRPs of the revertant strains fell in to different classes termed C. more...

Genome analysis of C. jejuni and C. coli isolated from different regions of the same pig

(Submitter supplied) C. coli is the predominant Campylobacter strain that is found in pigs while C. jejuni if present will be 10- 100 folds less. Natural transformation can occur if there is a coexistence of both the strains in the intestine of pigs. Genome analyses were performed on a C. jejuni strain U101 isolated from the upper intestine and two C. coli strains, C101 and L101 isolated from caecum and lower intestine.

Global transcriptional analysis of Campylobacter jejuni NCTC 11168 in response to epinephrine and norepinephrine.

(Submitter supplied) During colonization in the host gastrointestinal tract, the enteric bacteria Campylobacter jejuni is exposed to a variety of signaling molecules including the catecholamine hormones epinephrine (Epi) and norepinephrine (NE). NE has been determined to stimulate the growth of C. jejuni as well as increase its pathogenicity. To investigate the mechanisms of NE or Epi on the biology of C. jejuni, the global gene expression profiles of C. more...

Campylobacter jejuni transcriptomic response to benzylisothiocyanate

(Submitter supplied) Campylobacter jejuni is a widespread pathogen responsible for most of the food-borne gastrointestinal diseases in Europe. For pathogen control in the food industry, the use of natural antimicrobial molecules is a promising strategy to avoid antibiotic treatments. Isothiocyanates are natural antimicrobial compounds which also display anti-cancer activity. Several studies described the chemoprotective effect of isothiocyanates on eukaryotic cells, but the antimicrobial mechanism is still poorly understood. more...

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

(Submitter supplied) 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. more...

The role of the Cj0440c gene in Campylobacter jejuni

(Submitter supplied) Cj0440c encodes a putative transcriptional regulator. To determine the role of Cj0440c in C.jejuni, we knocked out Cj0440c in the wild-type strain (S) to obtain the Cj0440c mutants (SM). Then we compared the transcriptome of the Cj0440c mutant with that of the parent strain using DNA microarray. These comparisons identified 19 genes that showed a≥2-fold change in expression in SM. The differentially expressed genes in SM encode proteins involved in flagellar biosynthesis, O-linked glycosylation and hypothetical proteins with unknown fuctions. more...

High-Resolution Transcriptome Maps Reveal Strain-Specific Regulatory Features of Multiple Campylobacter jejuni Isolates

(Submitter supplied) Campylobacter jejuni is currently the leading cause of bacterial gastroenteritis in humans. Comparison of multiple Campylobacter strains revealed a high genetic and phenotypic diversity. However, little is known about differences in transcriptome organization, gene expression, and small RNA (sRNA) repertoires. Here we present the first comparative primary transcriptome analysis based on the differential RNA–seq (dRNA–seq) of four C. more...
