TL;DR: Overall, campylobacteriosis is still one of the most important infectious diseases that is likely to challenge global health in the years to come.
Abstract: Campylobacter jejuni infection is one of the most widespread infectious diseases of the last century. The incidence and prevalence of campylobacteriosis have increased in both developed and developing countries over the last 10 years. The dramatic increase in North America, Europe, and Australia is alarming, and data from parts of Africa, Asia, and the Middle East indicate that campylobacteriosis is endemic in these areas, especially in children. In addition to C. jejuni, there is increasing recognition of the clinical importance of emerging Campylobacter species, including Campylobacter concisus and Campylobacter ureolyticus. Poultry is a major reservoir and source of transmission of campylobacteriosis to humans. Other risk factors include consumption of animal products and water, contact with animals, and international travel. Strategic implementation of multifaceted biocontrol measures to reduce the transmission of this group of pathogens is paramount for public health. Overall, campylobacteriosis is still one of the most important infectious diseases that is likely to challenge global health in the years to come. This review provides a comprehensive overview of the global epidemiology, transmission, and clinical relevance of Campylobacter infection.

TL;DR: La bacteriemia es una presentacion atipica de la infeccion por Campylobacter jejuni, y es mas frecuente en pacientes con inmunodepresion avanzada debido al VIH u otras enfermedades sistemicas.
Abstract: La bacteriemia es una presentacion atipica de la infeccion por Campylobacter jejuni , y es mas frecuente en pacientes con inmunodepresion avanzada debido al VIH u otras enfermedades sistemicas. Debido a la terapia antiretroviral, en las ultimas decadas el numero de casos ha disminuido. Presentamos el caso de una mujer en situacion de calle, con VIH en etapa C3, que curso con una bacteriemia por C. jejuni durante su hospitalizacion por una tuberculosis pulmonar. Realizamos una breve revision de bacteriemia por C. jejuni en pacientes VIH.

TL;DR: All aspects of Campylobacter as a foodborne pathogen are reviewed, including several virulence factors and toxins which lead to illness in human.
Abstract: Food borne pathogens significantly cause illness in human which vary from mild symptoms to life threatening disease depending on the nature of microbial pathogens. Bacteria are almost responsible for 75% of food borne diseases in human. The food products especially of animal origin or their by products serve as the major source of transmission of food borne pathogens. All types of meat mainly beef, lamb and chicken and their by products can be contaminated with food borne pathogens like Campylobacter, Salmonella, Staphylococcus, E. coli and Listeria. These bacterial pathogens are equipped with several virulence factors and toxins which lead to illness in human. The severity of the disease mainly depends on the virulence of ingested pathogen. Campylobacter has been reported as the most frequent causative agent regarding foodborne illness. This article is aimed to review all aspects of Campylobacter as a foodborne pathogen.

TL;DR: The data indicate that PCR methodology is inaccurate to characterize the prevalence of the cdt genes, since negative PCR detection can be the result of divergences in the sequence used for primer design rather than indicating the absence of a specific gene.
Abstract: Campylobacter, a major cause of food‐borne gastroenteritis worldwide, colonize the gastrointestinal tract of a wide range of animals, being birds the main reservoir. The mechanisms involved in the interaction of Campylobacter with the different hosts are poorly understood. The cytolethal distending toxin, encoded in the cdtABC operon, is considered a pivotal virulence factor during human infection. Differences in the prevalence of cdtABC genes in Campylobacter isolates from three distinct origins (wild birds, broiler chickens and humans) prompted us to further characterize their allelic variability. The sequence of cdtABC is highly conserved among broiler and human isolates. A high diversity of cdtABC alleles was found among wild bird isolates, including several alleles that do not produce any functional CDT. These results suggest that specific variants of the cdtABC operon might define the host range of specific Campylobacter jejuni isolates. Moreover, our data indicate that PCR methodology is inaccurate to characterize the prevalence of the cdt genes, since negative PCR detection can be the result of divergences in the sequence used for primer design rather than indicating the absence of a specific gene.

TL;DR: In this paper , the authors describe a case of Campylobacter fetus bacteremia related to vascular prosthesis and pseudoaneurysm infection, with a review of the literature.
Abstract: Background. Campylobacter fetus rarely causes gastrointestinal diseases but shows an affinity for the endovascular epithelium. Methods. We describe a case of C. fetus bacteremia related to vascular prosthesis and pseudoaneurysm infection, with a review of the literature. Results. A 67-year-old male was admitted with a history of fever, weakness and painful swelling of the groin. After unsuccessful treatment with ciprofloxacin, the patient was transferred to our hospital, where he had been previously treated for aortoiliac occlusive disease including a prosthetic aortobifemoral and popliteal bypass with polyester graft placement. An angiography showed a pseudoaneurysm in the groin and, therefore, repair of the pseudoaneurysm, removal of the prosthesis and biologic graft placement were performed. Blood cultures and tissue samples of the vascular prosthesis and pseudoaneurysm yielded C. fetus resistant to ciprofloxacin. The patient was treated with meropenem for four weeks, followed by amoxicillin-clavulanate for another two weeks after discharge. Eight previously published cases of C. fetus bacteremia due to infected cardiovascular prosthetic devices (prosthetic heart valves, implantable cardioverter-defibrillators and a permanent pacemaker) were summarized in the review. Conclusions. To our knowledge, this is the first report of a C. fetus bacteremia related to post-surgical infection of a vascular prosthesis causing a pseudoaneurysm.

TL;DR: Two important processes have occurred to legitimize these conditions, and to increase attention toward the research and clinical care of patients with functional gastrointestinal disorders (FGID), a shift in conceptualizing these disorders from a disease-based, reductionistic model, to a more integrated, biopsychosocial model of illness.

TL;DR: Overabundance of Fusobacterium sequences in tumor versus matched normal control tissue is verified by quantitative PCR analysis from a total of 99 subjects, and a positive association with lymph node metastasis is observed.
Abstract: An estimated 15% or more of the cancer burden worldwide is attributable to known infectious agents. We screened colorectal carcinoma and matched normal tissue specimens using RNA-seq followed by host sequence subtraction and found marked over-representation of Fusobacterium nucleatum sequences in tumors relative to control specimens. F. nucleatum is an invasive anaerobe that has been linked previously to periodontitis and appendicitis, but not to cancer. Fusobacteria are rare constituents of the fecal microbiota, but have been cultured previously from biopsies of inflamed gut mucosa. We obtained a Fusobacterium isolate from a frozen tumor specimen; this showed highest sequence similarity to a known gut mucosa isolate and was confirmed to be invasive. We verified overabundance of Fusobacterium sequences in tumor versus matched normal control tissue by quantitative PCR analysis from a total of 99 subjects (p = 2.5 × 10(-6)), and we observed a positive association with lymph node metastasis.

TL;DR: The composition of the microbiota in colorectal carcinoma is characterized using whole genome sequences from nine tumor/normal pairs and Fusobacterium sequences were enriched in carcinomas, confirmed by quantitative PCR and 16S rDNA sequence analysis of 95 carcinoma/normal DNA pairs.
Abstract: The tumor microenvironment of colorectal carcinoma is a complex community of genomically altered cancer cells, nonneoplastic cells, and a diverse collection of microorganisms. Each of these components may contribute to carcinogenesis; however, the role of the microbiota is the least well understood. We have characterized the composition of the microbiota in colorectal carcinoma using whole genome sequences from nine tumor/normal pairs. Fusobacterium sequences were enriched in carcinomas, confirmed by quantitative PCR and 16S rDNA sequence analysis of 95 carcinoma/normal DNA pairs, while the Bacteroidetes and Firmicutes phyla were depleted in tumors. Fusobacteria were also visualized within colorectal tumors using FISH. These findings reveal alterations in the colorectal cancer microbiota; however, the precise role of Fusobacteria in colorectal carcinoma pathogenesis requires further investigation.

TL;DR: Campylobacters are a relatively unrecognised cause of acute enteritis, but these findings suggest that they may be a common cause, and poultry may be the primary source of the organism.
Abstract: By selective culture campylobacters (C jejuni and C coli) were isolated from the faeces of 57 (7-1%) out of 803 unselected patients with diarrhoea; none were isolated from 194 people who had not got diarrhoea. Specific agglutinins were found in the sera of 31 out of 38 patients with campylobacter enteritis and 10 of them had a rising titre. Half the patients were aged 15 to 44 years, but the incidence was highest in young children. All the patients with campylobacters had a distinctive clinical illness with severe abdominal pain. Campylobacters are a relatively unrecognised cause of acute enteritis, but these findings suggest that they may be a common cause. Spread of infection was observed within 12 out of 29 households, and in these cases children were usually implicated. Several patients were apparently infected from chickens, both live and dressed, and poultry may be the primary source of the organism. In two cases dogs with diarrhoea were found to be infected with strains indistinguishable from their human contacts. Ten patients acquired their infections while travelling abroad.
