Faecal microbiota transplantation (FMT) is an important therapeutic option for Clostridium difficile infection. Promising findings suggest that FMT may play a role also in the management of other disorders associated with the alteration of gut microbiota. Although the health community is assessing FMT with renewed interest and patients are becoming more aware, there are technical and logistical issues in establishing such a non-standardised treatment into the clinical practice with safety and proper governance...

BACKGROUND: The Clostridium difficile rate in symptomatic patients represents both those with C. difficile infection (CDI) and those with colonization. To predict the extent of CDI overdiagnosis, we compared the asymptomatic colonization rate to the symptomatic positivity rate in hospitalized patients using nucleic acid testing. METHODS: Between July 2014 and April 2015, formed stool samples were collected from asymptomatic patients after admission to 3 hospital wards at the Stanford Hospital...

BACKGROUND: Clostridium difficile bacteria are a leading cause of infectious diarrhea. This is an anaerobic, gram-positive and spore-forming rod responsible for significant morbidity and mortality, especially among elderly hospitalized patients. Standard management of C. difficile-associated diarrhea (CDAD) consists of discontinuing a causative antibiotic, correcting fluid-electrolytes imbalance and initiating an antibiotic treatment for CDAD. Alternative approaches for prevention of CDAD include probiotics...

Clostridium difficile is the most common cause of nosocomial diarrhea, resulting in significant morbidity and mortality in hospitalized patients. Oncology patients are particularly at risk of this infection secondary to frequent exposure to known risk factors. In a population in which diarrhea is a common adverse effect of chemotherapeutic regimens, diagnosis can be challenging secondary to current limitations in testing to differentiate between colonization and active infection. Although several currently available antimicrobial therapies achieve resolution of symptoms in this population, further research is needed to determine which agent least affects the host intestinal microbiota, especially in times of neutropenia and mucosal barrier injury...

We evaluated the performance of an early prototype core molecular mirroring nuclear magnetic resonance detection platform (Mentor-100) to detect toxigenic Clostridium difficile from stool. This technology uses customized nanoparticles bound to target specific oligonucleotide probes that form binaries in the presence of nucleic acid from the target microorganism. Liquid patient stool specimens were seeded with C. difficile or other Clostridium species to determine the analytical sensitivity and specificity. Samples underwent nucleic acid extraction and target amplification with probes conjugated with iron nanoparticles...

BACKGROUND: Clostridium difficile infection (CDI) is a common complication of inflammatory bowel diseases (IBDs) and is associated with worse outcome. Variable rates of colectomy have been reported among IBD complicated by CDI. We conducted a systematic review and meta-analysis of studies to assess the association between CDI and colectomy among patients with IBD. METHODS: The literature was systematically searched using PubMed from inception through April 2016...

Adults with cystic fibrosis (CF) have significant rates of asymptomatic Clostridium difficile carriage and are frequently exposed to risk factors for C. difficile infection (CDI). Despite this, the rate of reported CDI in CF is low. We describe three cases of near fatal CDI in adults with CF and review the literature regarding presentation, management, and recurrence prevention. Early recognition is important as the clinical presentation may be atypical and the illness can be severe and even life-threatening...

In 2010, we published an initial point-counterpoint on laboratory diagnosis of C. difficile infection (CDI). At that time, nucleic acid amplification tests (NAATs) were just becoming commercially available, and the idea of algorithmic approaches to CDI was being explored. Now there are numerous NAATs in the marketplace and based on recent proficiency test surveys, they have become the predominant method used for CDI diagnosis in the United States. At the same time, there is a body of literature that suggests that NAATs lack clinical specificity and thus inflate CDI rates...

Fecal microbiota transplantation is an efficacious and inexpensive therapy for recurrent Clostridium difficile, yet its safety is thought to depend on appropriate fecal donor screening. FDA guidance for regulation of this procedure is in flux but screening and manufacture of fecal material from asymptomatic donors presents many challenges to clinical laboratories. This minireview summarizes FDA regulatory changes, principles of donor selection and recommended laboratory screening for fecal microbiota transplantation...

Clostridium difficile is an emerging cause of healthcare associated infections. In nine hospitals of an Italian Local Health Authority the episodes of C. difficile infection (CDI) were identified using the data registered by the centralized Laboratory Information System, from 2010 to 2015. CDI incidence (positive patients for A and/or B toxins per patients-days) was analysed per year, hospital, and ward. A number of cases approximately equivalent to the mean of identified cases per year were studied retrospectively to highlight the risk factors associated to CDI and their severity...

Prevotella phocaeensis sp. nov. strain SN19(T) (= DSM 103364) is a new species isolated from the gut microbiota of patient with colitis due to Clostridium difficile. Strain SN19(T) is Gram-negative rod-shaped bacteria, strictly anaerobic, nonmotile and non-endospore forming. The predominance fatty acid is hexadecanoic acid. Its 16S rRNA showed a 97.70% sequence identity with its phylogenetically closest species, Prevotella oralis. The genome is 2 922 117 bp long and contains 2486 predicted genes including 56 RNA genes...

We resequenced the genome of Clostridium difficile 630Δerm (DSM 28645), a model strain commonly used for the generation of insertion mutants. The genome sequence was obtained by a combination of single-molecule real-time (SMRT) and Illumina sequencing technology. Detailed manual curation and comparison to the previously published genomic sequence revealed sequence differences including inverted regions and the presence of plasmid pCD630. Manual curation of our previously deposited genome sequence of the parental strain 630 (DSM 27543) led to an improved genome sequence...

Exposing Clostridium difficile spores to germinants in a quaternary ammonium matrix was an effective method to reduce environmental contamination by sensitizing the spores, leaving them susceptible to ambient conditions and enhancing killing by acid, high-intensity visible light, and radiation.

BACKGROUND: Clostridium difficile infection (CDI) can be transmitted from patient to patient by the hands of health care workers (HCWs); however, the relative importance of this route in the spread of C difficile in the hospital is currently unknown. Our aim was to review studies examining HCWs' hand carriage and its potential role in CDI transmission. METHODS: First, English-speaking references addressing HCWs' hand sampling obtained from the PubMed database were reviewed...

BACKGROUND & AIMS: Nosocomial infection with Clostridium difficile pose a considerable problem despite numerous attempts by health care workers to reduce risk of transmission. Asymptomatic carriers of C difficile might spread their infection to other patients. We investigated the effects of of asymptomatic carriers on nosocomial C difficile infections. METHODS: We performed a population-based prospective cohort study at 2 university hospitals in Denmark, screening all patients for toxigenic C difficile in the intestine upon admittance, from October 1, 2012, to January 31, 2013...

OBJECTIVE: Recently, metabolomics studies have suggested that the neurotransmitter γ-amino butyric acid (GABA) may modulate C. difficile infection (CDI) pathogenesis. In the present study, we investigated the association between GABA-modulating pharmaceuticals and CDI development. METHODS: In July-December 2013, we performed a matched, retrospective case-control study in Skåne county, Sweden, to assess the association between the use of GABA-modulators (defined as regular use of at least one of the following: zolpidem, zopiclone, benzodiazepines, gabapentin, pregabalin or baclofen) and CDI...
