چکیده

An unusual increase in the number of Campylobacter concisus isolates found in stool cultures provoked an outbreak investigation at Bern University Hospital. No epidemiological links were found between the cases, and the Campylobacter isolates were clonally unrelated. A change in culture conditions to a hydrogen-rich atmosphere enhancing growth of C. concisus was deemed responsible for this pseudo-outbreak.

Development and Evaluation of a Multiplex PCR for the Detection of Campylobacter concisus and Other Campylobacter spp. from Gastroenteritis Cases

We developed and evaluated a multiplex PCR (m-PCR) for application in routine diagnostic laboratories to detect Campylobacter spp. in stool samples including C. concisus, C. jejuni, and C. coli. When this m-PCR was applied on spiked faecal samples, C. concisus, C. jejuni, and C. coli were specifically identified at 105 cells/gm of faeces. To compare the sensitivity of the m-PCR with conventiona...

A culture-independent sequence-based metagenomics approach to the investigation of an outbreak of Shiga-toxigenic Escherichia coli O104:H4.

IMPORTANCE Identification of the bacterium responsible for an outbreak can aid in disease management. However, traditional culture-based diagnosis can be difficult, particularly if no specific diagnostic test is available for an outbreak strain. OBJECTIVE To explore the potential of metagenomics, which is the direct sequencing of DNA extracted from microbiologically complex samples, as an ope...

Complete Genome Sequence of Campylobacter concisus ATCC 33237T and Draft Genome Sequences for an Additional Eight Well-Characterized C. concisus Strains

We report the complete genome sequence of the Campylobacter concisus type strain ATCC 33237 and the draft genome sequences of eight additional well-characterized C. concisus strains. C. concisus has been shown to be a genetically heterogeneous species, and these nine genomes provide valuable information regarding the diversity within this taxon.

Examination of the Anaerobic Growth of Campylobacter concisus Strains

Campylobacter concisus is an oral bacterium that is associated with intestinal diseases. C. concisus was previously described as a bacterium that requires H2-enriched microaerobic conditions for growth. The level of H2 in the oral cavity is extremely low, suggesting that C. concisus is unlikely to have a microaerobic growth there. In this study, the anaerobic growth of C. concisus was investiga...

Optimized cultivation of Campylobacter concisus from gut mucosal biopsies in inflammatory bowel disease

BACKGROUND Campylobacter concisus is a commensal of the human oral flora that has been linked to prolonged diarrhea and inflammatory bowel disease (IBD). It has been detected more often from intestinal biopsies in patients with IBD compared to healthy controls using PCR-based techniques, whereas the number of C. concisus culture-positive biopsies in previous studies has been very limited. Deter...
