| development of a novel chromogenic medium for improved campylobacter detection from poultry samples. | the presence of expanded-spectrum β-lactamase (esbl)-producing escherichia coli is a common problem in the isolation of campylobacter from poultry samples using conventional cefoperazone-based selective media. a novel chromogenic medium (cm-ht), based on modified charcoal cefoperazone deoxycholate agar (mccda), has been developed as a solution for improved campylobacter detection from poultry samples. although the basic components of cm-ht are the same as mccda, cm-ht uses both granular charcoal ... | 2015 | 26319731 |
| are campylobacters now capable of carbo-loading? | campylobacters are a leading cause of gastrointestinal morbidity worldwide and the majority of human infections are triggered by eating foods contaminated with campylobacter jejuni or campylobacter coli. campylobacters are equally notorious for their ability to mimic human glycoconjugate structures and for their capacity to synthesize both n- and o-linked glycoproteins. these species were once considered to be asaccharolytic, but it was recently shown that several strains possess a pathway for f ... | 2015 | 26259768 |
| high prevalence and genetic diversity of campylobacter jejuni in wild crows and pigeons. | the occurrence, seasonal variation and genetic diversity of campylobacter spp. in pigeons and crows over a 1-year period were evaluated. campylobacter spp. were isolated from 166 (34.6 %) out of 480 wild bird faecal samples. the occurrence of campylobacter spp. in faecal samples was higher among crows (39.2 %) than pigeons (30.0 %), (p < 0.05). campylobacter jejuni was the most common species detected among wild bird faecal samples (98.2 %). meanwhile, campylobacter coli prevalence in wild bird ... | 2015 | 26228635 |
| a new variant of cytolethal distending toxin in a clinical isolate of campylobacter hyointestinalis. | increasing numbers of campylobacter hyointestinalis have been isolated from humans and animals with gastroenteritis, although the virulence mechanism of this species remains largely unknown. here, we show that c. hyointestinalis isolated from a patient with diarrhoea in thailand produced a novel variant of cytolethal distending toxin (cdt). sequencing of a 13 965 bp genomic region of c. hyointestinalis carrying the genes coding for ch-cdt revealed three orfs of 798, 804 and 537 bp, which code fo ... | 2015 | 26220191 |
| adherence reduction of campylobacter jejuni and campylobacter coli strains to hep-2 cells by mannan oligosaccharides and a high-molecular-weight component of cranberry extract. | campylobacter infections are a leading cause of human bacterial gastroenteritis in the united states and are a major cause of diarrheal disease throughout the world. colonization and subsequent infection and invasion of campylobacter require that the bacteria adhere to the surface of host cells. agents that inhibit adherence could be used prophylactically to reduce campylobacter carriage and infection. mannan oligosaccharides (mos) have been used as a feed supplement in livestock animals to impr ... | 2015 | 26219363 |
| microarray on digital versatile disc for identification and genotyping of salmonella and campylobacter in meat products. | highly portable, cost-effective, and rapid-response devices are required for the subtyping of the most frequent food-borne bacteria; thereby the sample rejection strategies and hygienization techniques along the food chain can be tailor-designed. here, a novel biosensor is presented for the generic detection of salmonella and campylobacter and the discrimination between their most prevalent serovars (salmonella enteritidis, salmonella typhimurium) and species (campylobacter jejuni, campylobacter ... | 2015 | 26198111 |

| real-time pcr detection of campylobacter spp.: a comparison to classic culturing and enrichment. | the major disadvantage of the current gold standard for detection of the food pathogen campylobacter, i.e. culturing, is the lengthy procedure. in this study we assessed the use of real-time pcr for detection of campylobacter. to this end, 926 poultry samples, taken from transport containers and broiler caeca in the netherlands in 2007, were subjected to three different real-time pcr detection methods: one targeting the campylobacter jejuni hipo gene, one targeting the campylobacter coli glya ge ... | 2015 | 26187833 |
| restoring the selectivity of modified charcoal cefoperazone deoxycholate agar for the isolation of campylobacter species using tazobactam, a β-lactamase inhibitor. | extended spectrum β-lactamase (esbl) producing escherichia coli have emerged as a contaminant on modified charcoal cefoperazone deoxycholate agar (mccda) when attempting to selectively isolate campylobacter spp. from poultry. e. coli are particularly problematic given their ability to grow under microaerophilic conditions and have been shown to outcompete campylobacter species making campylobacter detection or enumeration difficult. this paper recommends a novel method for restoring the selectiv ... | 2015 | 26119190 |
| the evolution of campylobacter jejuni and campylobacter coli. | the global significance of campylobacter jejuni and campylobacter coli as gastrointestinal human pathogens has motivated numerous studies to characterize their population biology and evolution. these bacteria are a common component of the intestinal microbiota of numerous bird and mammal species and cause disease in humans, typically via consumption of contaminated meat products, especially poultry meat. sequence-based molecular typing methods, such as multilocus sequence typing (mlst) and whole ... | 2015 | 26101080 |
