Enhanced biofilm formation and multi-host transmission evolve from divergent genetic backgrounds in Campylobacter jejuni. [PDF]
Environ Microbiol, 2015 Summary Multicellular biofilms are an ancient bacterial adaptation that offers a protective environment for survival in hostile habitats. In microaerophilic organisms such as C ampylobacter , biofilms play a key

Wild bird-associated Campylobacter jejuni isolates are a consistent source of human disease, in Oxfordshire, United Kingdom. [PDF]
Environ Microbiol Rep, 2015 The contribution of wild birds as a source of human campylobacteriosis was investigated in Oxfordshire, United Kingdom (UK) over a 10 year period. The probable origin of human Campylobacter jejuni genotypes, as described by multilocus sequence typing, was estimated by comparison with reference populations of isolates from farm animals and five wild ...

Hemerythrins in the microaerophilic bacterium Campylobacter jejuni help protect key iron-sulphur cluster enzymes from oxidative damage. [PDF]
Environ Microbiol, 2014 Summary Microaerophilic bacteria are adapted to low oxygen environments, but the mechanisms by which their growth in air is inhibited are not well understood. The citric acid cycle in the microaerophilic pathogen C ampylobacter ...

Role of capsular modified heptose in the virulence of
Molecular Microbiology, 2015 SummaryThe Campylobacter jejuni capsular polysaccharide is important for virulence and often contains a modified heptose. In strain ATCC 700819 (a.k.a. NCTC 11168), the modified heptose branches off from the capsular backbone and is directly exposed to the environment.

The
Molecular Microbiology, 2015 SummaryCampylobacter jejuni is a leading cause of food‐borne gastroenteritis in humans. It lives commensally in the gastrointestinal tract of animals, and tolerates variable conditions during transit/colonization of susceptible hosts. The C. jejuni CprRS two‐component system contains an essential response regulator (CprR), and deletion of the cprS ...

The impairment of methylmenaquinol:fumarate reductase affects hydrogen peroxide susceptibility and accumulation in
MicrobiologyOpen, 2014 The methylmenaquinol:fumarate reductase (Mfr) of Campylobacter jejuni is a periplasmic respiratory (redox) protein that contributes to the metabolism of fumarate and displays homology to succinate dehydrogenase (Sdh). Since chemically oxidized redox-enzymes, including fumarate reductase and Sdh, contribute to the generation of oxidative stress in ...

Flagellar biosynthesis exerts temporal regulation of secretion of specific
Molecular Microbiology, 2014 SummaryThe Campylobacter jejuni flagellum exports both proteins that form the flagellar organelle for swimming motility and colonization and virulence factors that promote commensal colonization of the avian intestinal tract or invasion of human intestinal cells respectively. We explored how the C. jejuni flagellum is a versatile secretory organelle by

Utilization of host‐derived cysteine‐containing peptides overcomes the restricted sulphur metabolism of
Molecular Microbiology, 2014 SummaryThe non‐glycolytic food‐borne pathogen Campylobacter jejuni successfully colonizes the intestine of various hosts in spite of its restricted metabolic properties. While several amino acids are known to be used by C. jejuni as energy sources, none of these have been found to be essential for growth.
