Niche-adaptive evolution in Campylobacter jejuni
Campylobacter jejuni is the leading causative agent of human bacterial gastroenteritis. Human C. jejuni infection (campylobacteriosis) is frequently associated with poultry; through consumption of undercooked products, cross contamination from raw meats, or through direct contact with birds or …

Genome sequence of the hyperinvasive Campylobacter jejuni strains
Campylobacter jejuni is the world’s major cause of gastroenteritis in humans. Although motility, toxin production, adhesion and invasion are some of the key factors associated with C. jejuni pathogenesis, their mechanism in the disease process remains unclear. The key aim of this project is to …

Isolation, growth and epidemiology of campylobacter jejuni / coli
… metabisulphite (0.05%) gave slightly fewer Campylobacter isolations than the SEES when evaluated with various types of specimens and was also less selective. Maximum isolation rates were achieved by incubating broths at 42 0C and subculturing after 24h and 42h. Growth studies of three …

The coaggregative abilities of lactobacilli and Campylobacter jejuni
Campylobacter jejuni is a pathogen commonly found in poultry that is one of the main bacterial causes of foodborne diarrheal disease in humans. The aim of this study was to analyze the coaggregative abilities of lactic acid bacteria and C. jejuni as a means to reduce the colonization of C. jejuni …

Hyperinvasiveness in the major food-borne pathogen Campylobacter jejuni
Campylobacter jejuni is a common cause of human gastrointestinal infections. Invasion of host epithelial cells is believed to be an important virulence Mechanism of this bacterium. C. jejuni strains vary in their ability to invade the human epithelial cells and some of the strains are …

Butyrate Sensing by Campylobacter jejuni Impacts Bacterial-Host Interactions
… regions of the host intestines. Indeed, Campylobacter jejuni, a commensal bacterium of the lower intestinal tract of avian species and a leading cause of bacterial diarrheal disease in humans, recognizes intestinal niches that support growth by sensing molecular cues produced by the …

Signalling Molecule Production by Escherichia coli and Campylobacter jejuni
… and laboratory isolates of Escherichia coli and Campylobacter jejuni has been investigated in this study. Laboratory, blood and urine E.coli isolates were analysed via three reporter strain bioassays for putative AHL production. The initial results indicated that the E.coli blood isolates …

Campylobacter jejuni infection versus contamination of turkeys and chickens
… was conducted to determine the extent in which Campylobacter jejuni colonized live birds would survive evisceration and contaminate the processed carcasses. Birds were infected with a marker strain of Campylobacter jejuni and allowed to grow to market age. Cloacal and fecal samples were analyzed …

Signals and Sensory Mechanisms that Impact Campylobacter jejuni-Host Interactions
Campylobacter jejuni is a leading cause of bacterial diarrheal disease worldwide and a frequent commensal organism of the intestinal tract of poultry and other agriculturally-important animals. Upon infection of the avian host, C. jejuni likely responds to external stimuli present within the …

Lactobacillus strategies to reduce Campylobacter jejuni colonization of broiler chickens
Campylobacter jejuni is one of the leading causes of foodborne bacterial illness in the world. The majority of cases of campylobacteriosis are associated with the consumption of raw or undercooked poultry meat or their cross-contamination with other food products. Strategies to reduce the presence …

Determinants Influencing Polar Flagellar Biosynthesis and Cell Division in Campylobacter jejuni
Campylobacter jejuni is a worldwide leading cause of bacterial gastrointestinal disease. The natural habitat of this organism is the gastrointestinal tracts of warm-blooded animals, especially poultry, where the bacterium promotoes a harmless commensal colonization. The abundance of C. jejuni in …
-
Identification and Characterization of Flagellar Co-expressed Determinants (Feds) of Campylobacter jejuni
Campylobacter jejuni is the leading cause of bacterial gastroenteritis in humans throughout the world. In contrast to infection of humans, C. jejuni is a commensal organism of the intestinal tracts of wild and agriculturally-significant animals and avian species. Flagellar motility is the only …
-
Identification and characterization of Campylobacter jejuni factors relevant for the infection process
Campylobacter jejuni ist der in Industrieländern am weitesten verbreitete bakterielle Erreger von Lebensmittelerkrankungen. Alleine in Deutschland werden pro Jahr etwa 60 000 Fälle beschrieben. Trotz der vollständigen Sequenzierung des Genoms ist über die Pathogenese der Erkrankung wenig bekannt. …

The role of biofilms in Campylobacter jejuni survival in the food chain
Campylobacter jejuni is the leading cause of bacterial foodborne poisoning in the developed world. The impact of infection is mainly economic, however the disease can lead to severe post infection complications, such as Guillain–Barré syndrome. Despite the fastidious nature of C. jejuni, it is able …

Modified heptose synthesis in the Campylobacter jejuni capsule and its involvement in virulence
Campylobacter jejuni is the leading cause of gastroenteritis.Infections are endemic in developing countries and the emergence of antibiotic resistant isolates in developed countries underline the requirement for new therapeutic targets. C. jejuni possesses a capsule, which is important in …
-
Characterization of the Activation of the FlgSR Two-Component System in Campylobacter Jejuni
Epidemiological studies indicate that Campylobacter jejuni is the leading cause of bacterial gastroenteritis worldwide. This organism has the ability to live as a commensal or a pathogen, depending on the host with which it is associated. While colonization of the gastrointestinal tract of many …
-
Oxidative stress responses in Campylobacter jejuni: the role of the Peroxide Regulator PerR
Campylobacter jejuni is a microaerophilic foodborne pathogen capable of surviving the stressful, oxygen-exposed route from an avian host and entering into the human food chain. The ability of Campylobacter to survive oxidative stress is thought to contribute to the annual ~500,000 UK cases of …

Regulating Campylobacter jejuni flagellar gene expression: transcriptional and post-transcriptional mechanisms of control
The bacterial pathogen Campylobacter jejuni is the leading cause of foodborne gastroenteritis in the developed world. C. jejuni flagella are crucial virulence determinants, but the regulation of these complex organelles within different environments is not fully understood. Moreover, regulatory …
