BACKGROUND: Diarrhea is a common condition after solid organ transplant (SOT); Clostridium difficile-associated colitis (CDAC) is one of the most common infections after SOT. We documented previously that some types of enteritis are associated with an elevation of tacrolimus (TAC) trough concentrations by interfering with the drug's complex metabolism. PATIENTS AND METHODS: Tacrolimus concentrations of 25 SOT recipients including 12 renal and 13 liver recipients before, during, and after CDAC were analyzed retrospectively...

Fecal microbiota transplantation has been shown to be an effective treatment for patients with recurrent C. difficile colitis. Although fecal microbiota transplantation helps to re-establish a normal gut function in patients, the extent of the repopulation of the recipient microbial community varies. To further understand this variation, it is important to determine the fate of donor microbes in the patients following fecal microbiota transplantation. We have developed a new method that utilizes the unique single nucleotide variants of gut microbes to accurately identify microbes in paired fecal samples from the same individual taken at different times...

Fecal microbiota transplantation (FMT) is a relatively simple, promising treatment for recurrent Clostridium difficile infection. While there are a wide variety of approaches including mode of delivery, the results are nonetheless encouraging, even amongst younger children. Experience with FMT in the pediatric population is increasing, showing similar success compared to adults. This article will provide an overview of C. difficile infection along with review of the rationale, methods and complications of FMT including the current experience of FMT in children...

OBJECTIVES: Studies are conflicting regarding the association of the North American pulsed-field gel electrophoresis type 1 (NAP1) strain in Clostridium difficile infection (CDI) and outcomes. We evaluated the association of NAP1 with healthcare-associated CDI disease severity, mortality, and recurrence at our academic medical center. METHODS: Healthcare-associated CDI cases were identified from November 1, 2011 through January 31, 2013. Multivariable regression models were used to evaluate the associations of NAP1 with severe disease (based on the Hines VA severity score index), mortality, and recurrence...

OBJECTIVE: We aimed to compare the outcomes of patients with C.difficile infection (CDI) treated either with tigecycline associated with vancomycin, or with vancomycin alone. METHODS: This single-centre retrospective cohort study included all adults hospitalized from September 2014 through August 2015 for symptomatic, incident CDI confirmed by polymerase chain reaction for C.difficile toxin in stools. The primary outcome was the rate of favourable outcome, defined as a composite of clinical response (resolution of symptoms without need for additional CDI therapy) and achieving discharge without CDI-related surgery or intensive care; a secondary outcome was CDI recurrence...

Clostridium difficile is the primary cause of healthcare associated diarrhoea globally and produces spores which are resistant to commonly used biocides and are able persist on contaminated surfaces for months. This study examined the effect of sublethal concentrations of the biocide sodium dichloroisocyanurate (NaDCC) on the viability of spores produced by 21 clinical isolates of C. difficile representing a range of PCR ribotypes. Spores exposed to 500 ppm NaDCC for 10 minutes exhibited between a 4 - 6 log10 reduction in viability which was independent of spore PCR ribotype...

BACKGROUND: The horse intestinal tract is sensitive and contains a highly complex microbial population. A shift in the microbial population can lead to various issues such as inflammation and colic. The use of nutraceuticals in the equine industry is on the rise and curcumin is thought to possess antimicrobial properties that may help to minimize the proliferation of opportunistic bacteria. METHODS: Four cecally-cannulated horses were utilized to determine the optimal dose of liposomal-curcumin (LIPC) on reducing Streptococcus bovis/equinus complex (SBEC), Escherichia coli K-12, Escherichia coli general, Clostridium difficile, and Clostridium perfringens in the equine hindgut without adversely affecting cecal characteristics...

Clostridium difficile infection (CDI) is the most common nosocomial infection in the U.S. 25% of CDI patients go on to develop recurrent CDI (rCDI) following current standard of care (SOC) therapy, leading to morbidity, mortality and economic loss. The first passive immunotherapy drug targeting C.difficile toxin B (bezlotoxumab) has been approved recently by the FDA and EMA for prevention of rCDI. Areas covered: A body of key studies was selected and reviewed by the authors. The unmet needs in CDI care were ascertained with emphasis in rCDI, including the epidemiology, pathophysiology and current management...

In the past decade, Clostridium difficile has emerged as an important gut pathogen. This anaerobic, Gram-positive bacterium is the main cause of infectious nosocomial diarrhea. Whereas much is known about the mechanism through which the C. difficile toxins cause diarrhea, relatively little is known about the dynamics of adhesion and motility, which is mediated by cell surface proteins. This review will discuss the recent advances in our understanding of the sortase-mediated covalent attachment of cell surface (adhesion) proteins to the peptidoglycan layer of C...

A 75-year-old man was admitted with abdominal pain and fresh rectal bleeding. Significantly, he had no risk factors for Clostridium difficile infection. An abdominal CT demonstrated colonic thickening, and flexible sigmoidoscopy identified pseudomembranous colitis-like lesions. After initial treatment as C. difficile colitis, a stool sample revealed Escherichia coli O157:H7 infection. Antibiotic therapy was stopped due to the risk of lysis-mediated toxin release, but unfortunately, the patient continued to deteriorate...

BACKGROUND: Antibiotic stewardship programmes have been shown to reduce antibiotic use and hospital costs. We aimed to evaluate evidence of the effect of antibiotic stewardship on the incidence of infections and colonisation with antibiotic-resistant bacteria. METHODS: For this systematic review and meta-analysis, we searched PubMed, the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, and Web of Science for studies published from Jan 1, 1960, to May 31, 2016, that analysed the effect of antibiotic stewardship programmes on the incidence of infection and colonisation with antibiotic-resistant bacteria and Clostridium difficile infections in hospital inpatients...

The increased incidence of antibiotic resistant 'superbugs' has amplified the use of broad spectrum antibiotics worldwide. An unintended consequence of antimicrobial treatment is disruption of the gastrointestinal microbiota, resulting in susceptibility to opportunistic pathogens, such as Clostridium difficile. Paradoxically, treatment of C. difficile infections (CDI) also involves antibiotic use, leaving patients susceptible to re-infection. This serious health threat has led to an urgent call for the development of new therapeutics to reduce or replace the use of antibiotics to treat bacterial infections...

Clostridioides difficile (formerly Clostridium difficile) is a major nosocomial pathogen with an increasing number of community-acquired infections causing symptoms from mild diarrhea to life-threatening colitis. The pathogenicity of C. difficile is considered to be mainly associated with the production of genome-encoded toxins A and B. In addition, some strains also encode and express the binary toxin CDT. However; a large number of non-toxigenic C. difficile strains have been isolated from the human gut and the environment...
