| divergent distribution of the sensor kinase coss in non-thermotolerant campylobacter species and its functional incompatibility with the response regulator cosr of campylobacter jejuni. | two-component signal transduction systems are commonly composed of a sensor histidine kinase and a cognate response regulator, modulating gene expression in response to environmental changes through a phosphorylation-dependent process. cosr is an ompr-type response regulator essential for the viability of campylobacter jejuni, a major foodborne pathogenic species causing human gastroenteritis. although cosr is a response regulator, its cognate sensor kinase has not been identified in c. jejuni. ... | 2014 | 24587027 |
| a comparison between hippurate hydrolysis and multiplex pcr for differentiating campylobacter coli and campylobacter jejuni. | species identification is important for epidemiological, clinical and treatment purposes. the aim of this study was to find out whether hippurate hydrolysis is a reliable test for differentiating between campylobacter coli and campylobacter jejuni. to achieve this, hippurate hydrolysis test was compared with multiplex polymerase chain reaction (mpcr) for their ability to speciate c. coli and c. jejuni. eighteen campylobacter strains from poultry samples were used for this study. the results from ... | 2011 | 24575212 |

| antimicrobial resistance of bacterial enteropathogens isolated from stools in madagascar. | diarrheal diseases are a major public health problem in developing countries, and are one of the main causes of hospital admissions in madagascar. the pasteur institute of madagascar undertook a study to determine the prevalence and the pathogenicity of bacterial, viral and protozoal enteropathogens in diarrheal and non-diarrheal stools of children aged less than 5 years in madagascar. we present here the results of the analysis of antimicrobial susceptibility of the bacteria isolated during thi ... | 2014 | 24568189 |
| gram-negative flagella glycosylation. | protein glycosylation had been considered as an eccentricity of a few bacteria. however, through advances in analytical methods and genome sequencing, it is now established that bacteria possess both n-linked and o-linked glycosylation pathways. both glycosylation pathways can modify multiple proteins, flagellins from archaea and eubacteria being one of these. flagella o-glycosylation has been demonstrated in many polar flagellins from gram-negative bacteria and in only the gram-positive genera ... | 2014 | 24557579 |
| comparative genomics of unintrogressed campylobacter coli clades 2 and 3. | campylobacter jejuni and c. coli share a multitude of risk factors associated with human gastrointestinal disease, yet their phylogeny differs significantly. c. jejuni is scattered into several lineages, with no apparent linkage, whereas c. coli clusters into three distinct phylogenetic groups (clades) of which clade 1 has shown extensive genome-wide introgression with c. jejuni, yet the other two clades (2 and 3) have less than 2% of c. jejuni ancestry. we characterized a c. coli strain (76339) ... | 2014 | 24524824 |

| biological roles of the o-methyl phosphoramidate capsule modification in campylobacter jejuni. | campylobacter jejuni is a major cause of bacterial gastroenteritis worldwide, and the capsular polysaccharide (cps) of this organism is required for persistence and disease. c. jejuni produces over 47 different capsular structures, including a unique o-methyl phosphoramidate (meopn) modification present on most c. jejuni isolates. although the meopn structure is rare in nature it has structural similarity to some synthetic pesticides. in this study, we have demonstrated, by whole genome comparis ... | 2014 | 24498018 |
| [microbiological diagnosis of infections caused by campylobacter jejuni and campylobacter coli in humans]. | campylobacter jejuni and campylobacter coli are gram-negative, microaerophilic bacteria which are worldwide in distribution, causing a zoonotic disease in humans called campylobacteriosis. these infections are mainly caused by eating contaminated food products, most often improperly prepared poultry meat. campylobacteriosis usually takes the form of gastroenteritis, or inflammation of the intestines, and the characteristic symptoms are watery-mucous diarrhea often with the presence of blood in s ... | 2014 | 24491895 |
| distribution of indigenous bacterial pathogens and potential pathogens associated with roof-harvested rainwater. | the harvesting of rainwater is gaining acceptance among many governmental authorities in countries such as australia, germany, and south africa, among others. however, conflicting reports on the microbial quality of harvested rainwater have been published. to monitor the presence of potential pathogenic bacteria during high-rainfall periods, rainwater from 29 rainwater tanks was sampled on four occasions (during june and august 2012) in a sustainable housing project in kleinmond, south africa. t ... | 2014 | 24487540 |
| comparative analysis and limitations of ethidium monoazide and propidium monoazide treatments for the differentiation of viable and nonviable campylobacter cells. | the lack of differentiation between viable and nonviable bacterial cells limits the implementation of pcr-based methods for routine diagnostic approaches. recently, the combination of a quantitative real-time pcr (qpcr) and ethidium monoazide (ema) or propidium monoazide (pma) pretreatment has been described to circumvent this disadvantage. in regard to the suitability of this approach for campylobacter spp., conflicting results have been reported. thus, we compared the suitabilities of ema and ... | 2014 | 24487529 |
