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: The health burden and direct costs of 14 infections commonly transmitted by food, considering the acute illness and subsequent sequelae and mortality, for the population of British Columbia, Canada, is estimated.
Abstract: Introduction Over one in eight Canadians is affected by a foodborne infection annually; however, the long-term consequences, including the risks and costs of sequelae, are unclear. We aim to estimate the health burden and direct costs of 14 infections commonly transmitted by food, considering the acute illness and subsequent sequelae and mortality, for the population of British Columbia, Canada (~4.7 million). Methods and analysis We will conduct a population-based retrospective cohort study of the British Columbia provincial population, over a 10-year study period (1 January 2005 to 31 December 2014). Exposure is defined as a provincially reported illness caused by Clostridium botulinum, Campylobacter, Cryptosporidium, Cyclospora, Giardia, hepatitis A virus, Listeria, non-typhoidal Salmonella spp, Salmonella Typhi, Salmonella Paratyphi, Shiga toxin-producing Escherichia coli, Shigella, Vibrio parahaemolyticus or Yersinia (excluding pestis). We will link individual-level longitudinal data from eight province-wide administrative health and reportable disease databases that include physician visits, hospitalisations and day surgeries, deaths, stillbirths, prescription medications (except those to treat HIV) and reportable foodborne diseases. Using these linked databases, we will investigate the likelihood of various sequelae and death. Hazard models will be used to estimate the risk of outcomes and their association with the type of foodborne infection. Epidemiological analyses will be conducted to determine the progression of illness and the fraction of sequelae attributable to specific foodborne infections. Economic analyses will assess the consequent direct healthcare costs. Ethics and dissemination This study has been approved by a University of Waterloo Research Ethics Committee (no 30645), the University of British Columbia Behavioral Research Ethics Board (no H16-00021) and McGill University’s Institutional Review Board (no A03-M12-19A). Results will be disseminated via presentations to academics, public health practitioners and knowledge users, and publication in peer-reviewed journals. Where such publications are not open access, manuscripts will also be available via the University of Waterloo’s Institutional Repository (https://uwspace.uwaterloo.ca).

TL;DR: The results of Enterobacterial Repetitive Intergenic Consensus Polymerase Chain Reaction revealed extensive genetic heterogeneity among both Arcobacter and Campylobacter isolates, revealing the necessity of improving the hygiene quality in slaughterhouses and other meat processing units as there are different sources of contamination.
Abstract: The present study aimed to isolate Arcobacter spp. and Campylobacter spp. from beef meat samples including cattle carcasses, cube meat and minced meat, and to determine the antibacterial susceptibility and genetic diversity of the recovered isolates. One hundred beef carcass surface samples from slaughterhouses and 100 beef meat samples (50 samples of cube meat and 50 minced meat) taken from different retail units were analysed. Of the examined samples, 17 (8.5%) and 43 (21.5%) were positive for Arcobacter spp. and Campylobacter spp. respectively. Twenty Arcobacter and 53 Campylobacter isolates were obtained from positive samples. Both Arcobacter and Campylobacter were concurrently isolated from 7 (3.5%) of the 17 positive samples. Arcobacter butzleri (18 isolates) and Campylobacter jejuni (37 isolates) were the most commonly isolated species. The results of Enterobacterial Repetitive Intergenic Consensus Polymerase Chain Reaction revealed extensive genetic heterogeneity among both Arcobacter and Campylobacter isolates. Seventeen and 30 different genotypes were identified in 18 A. butzleri and 37 C. jejuni isolates, respectively. Each of A. cryaerophilus, C. fetus and C. hyointestinalis isolates had two genotypes. Three and seven genotypes were identified in five C. lari and in seven C. coli isolates, respectively. While 5% of 20 Arcobacter isolates were resistant to amoxicillin-clavulanic acid, 5% of the isolates were resistant to neomycin. Of the 53 Campylobacter isolates, 9.43%, 22.64%, 7.54% and 3.77% were resistant to enrofloxacin, neomycin, tetracycline and streptomycin, respectively. Contaminated beef carcasses, cube meat and minced meat with various species and subspecies of arcobacters and campylobacters may pose a risk factor for human infections. Our study reveals the necessity of improving the hygiene quality in slaughterhouses and other meat processing units as there are different sources of contamination.

TL;DR: In this paper, the evolutionary development and the population diversity of the two most clinically relevant Campylobacter species; C. jejuni and C. coli were reviewed and the potential impact of horizontal gene transfer on host adaptation was discussed.
Abstract: The zoonotic pathogen Campylobacter is the leading cause for bacterial foodborne infections in humans. Campylobacters are most commonly transmitted via the consumption of undercooked poultry meat or raw milk products. The decreasing costs of whole genome sequencing enabled large genome-based analyses of the evolution and population structure of this pathogen, as well as the development of novel high-throughput molecular typing methods. Here, we review the evolutionary development and the population diversity of the two most clinically relevant Campylobacter species; C. jejuni and C. coli. The state-of-the-art phylogenetic studies showed clustering of C. jejuni lineages into host specialists and generalists with coexisting lifestyles in chicken and livestock-associated hosts, as well as the separation of C. coli isolates of riparian origin (waterfowl, water) from C. coli isolated from clinical and farm-related samples. We will give an overview of recombination between both species and the potential impact of horizontal gene transfer on host adaptation in Campylobacter. Additionally, this review briefly places the current knowledge of the population structure of other Campylobacter species such as C. lari, C. concisus and C. upsaliensis into perspective. We also provide an overview of how molecular typing methods such as multilocus sequence typing (MLST) and whole genome MLST have been used to detect and trace Campylobacter outbreaks along the food chain.

TL;DR: Interventions targeting five pathogens can substantially reduce the burden of moderate-to-severe diarrhoea and suggest new methods and accelerated implementation of existing interventions (rotavirus vaccine and zinc) are needed to prevent disease and improve outcomes.

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.
