Noa Eliakim-Raz, Jihad Bishara
This review summarizes the latest advances in treating and preventing Clostridium difficile infection (CDI), the most common infectious disease cause of nosocomial diarrhea in adults in developed countries. As customary antibiotic therapies against C. difficile, metronidazole and vancomycin, are broad spectrum, they affect greatly the gut microbiota, which result in very high recurrence rates. Therefore, new strategies are researched intensively. New therapies focus on limiting further destruction of the gut microbiota or restoring the microbiota to its pre-destructed state...

BACKGROUND: Convenient, reproducible, and rapid preservation of unique biological specimens is pivotal to their use in microbiome analyses. As an increasing number of human studies incorporate the gut microbiome in their design, there is a high demand for streamlined sample collection and storage methods that are amenable to different settings and experimental needs. While several commercial kits address collection/shipping needs for sequence-based studies, these methods do not preserve samples properly for studies that require viable microbes...

The human gut microbiome consists of many bacteria which are in symbiotic relationship with human beings. The gut microbial metabolism, as well as the microbial-host co-metabolism, has been found to greatly influence health and disease. Factors such as diet, antibiotic use and lifestyle have been associated with alterations in the gut microbial community and may result in several pathological conditions. For this reason, several strategies including fecal microbiota transplant and probiotic administration have been applied and proven to be feasible and effective in restoring the gut microbiota in humans...

CONTEXT: Review of the yeast Saccharomyces boulardii as a treatment option for the inflammatory bowel diseases (IBD) ulcerative colitis and Crohn's disease. OBJECTIVE: IBD is caused by an inappropriate immune response to gut microbiota. Treatment options could therefore be prebiotics, probiotics, antibiotics and/or fecal transplant. In this review, we have looked at the evidence for the yeast S. boulardii as a treatment option. MATERIAL AND METHODS: Searches in PubMed and the Cochrane Library with the MeSH words 'Saccharomyces boulardii AND IBD', 'Saccharomyces boulardii AND Inflammatory Bowel Disease', 'Saccharomyces boulardii AND ulcerative colitis' and 'Saccharomyces boulardii AND Crohn's disease' gave total a total of 80 articles...

Introduction: The Internet has become an increasingly popular resource for medical information. Fecal microbiota transplantation (FMT) has changed the treatment of Clostridium difficile with cure rates of 81% following one infusion of FMT, further studies have since validated these findings. The Medicines and Health care Products Regulatory Agency has classified FMT as a medicine and hence should be only utilized in strict clinical settings. Methods: We searched Facebook, Twitter, Google, and YouTube using the words "Faecal Microbiota Transplantation" and "FMT"...

The 2017 annual symposium organized by the University Medical Center Groningen in The Netherlands focused on the role of the gut microbiome in human health and disease. Experts from academia and industry examined interactions of prebiotics, probiotics, or vitamins with the gut microbiome in health and disease, the development of the microbiome in early-life and the role of the microbiome on the gut-brain axis. The gut microbiota changes dramatically during pregnancy and intrinsic factors (such as stress), in addition to extrinsic factors (such as diet, and drugs) influence the composition and activity of the gut microbiome throughout life...

BACKGROUND: Clostridium difficile infection (CDI) is a major cause of hospital-acquired diarrhea. Secondary bile acids were shown to confer resistance to colonization by C. difficile. 7α-dehydroxylation is a key step in transformation of primary to secondary bile acids and required genes have been located in a single bile acid-inducible (bai) operon in C. scindens as well as in C. hiranonis, two Clostridium sp. recently reported to protect against C. difficile colonization. AIM: To analyze baiCD gene abundance in C...

Objective Chronic systemic inflammation contributes to the pathogenesis of many age-related diseases. Although not well understood, alterations in the gut microbiota, or dysbiosis, may be responsible for age-related inflammation. Methods Using stroke as a disease model, we tested the hypothesis that a youthful microbiota, when established in aged mice, produces positive outcomes following ischemic stroke. Conversely, an aged microbiota, when established in young mice, produces negative outcomes after stroke...

BACKGROUND: Current therapies for against inflammatory bowel disease (IBD) are sometimes limited by high costs, high toxicities and/or undesirable side effects, reasons for which new treatments are constantly being developed and studied. In this regards an increasing mass of data has demonstrated that fecal transplantations and probiotic supplementations have shown promising effects and could be considered as adjunct IBD treatments to decrease some of the unwanted side effects caused by primary treatments...

Upon oral infection with Toxoplasma gondii cysts (76 K strain) tachyzoites are released into the intestinal lumen and cross the epithelial barrier causing damage and acute intestinal inflammation in C57BL/6 (B6) mice. Here we investigated the role of microbiota and IL-22 in T.gondii-induced small intestinal inflammation. Oral T.gondii infection in B6 mice causes inflammation with IFNγ and IL-22 production. In IL-22-deficient mice, T.gondii infection augments the Th1 driven inflammation. Deficiency in either IL-22bp, the soluble IL-22 receptor or Reg3γ, an IL-22-dependent antimicrobial lectin/peptide, did not reduce inflammation...

Fecal microbiota transplantation (FMT) is gaining attention for the treatment of ulcerative colitis (UC). Data from individual case studies have suggested that FMT may be beneficial for UC but the detailed microbial and molecular basis remains unknown. Here, we employ 16S rRNA gene sequencing and metabolomics to investigate the influence of FMT on gut microbial community composition and host metabolism in the dextran sulfate sodium (DSS) induced UC rat model. The findings from this pilot study suggest that FMT from normal donors to UC recipients could alleviate UC symptoms without close resemblance of donor's gut microbial and metabolic pattern...

Human microbiota-associated (HMA) mice are an important model to study the relationship between liver diseases and intestinal microbiota. We describe a new method to humanize conventional mice based on bowel cleansing with polyethylene glycol followed by fecal microbiota transplantation (FMT) from a human donor. Four successive bowel cleansings were sufficient to empty the intestine and decrease the microbiota by 90%. We then compared four different strategies based on the frequency of FMT over four weeks: (1) twice a week; (2) once a week; (3) two FMTs; (4) one FMT...

Hepatitis E virus (HEV), a non-enveloped single stranded RNA virus causes sporadic cases of hepatitis or outbreaks. The disease is generally self-limited although it may cause fulminant hepatitis in pregnant women, elderly, those with underlying chronic hepatitis, immunosuppressed, and transplant recipients. It is transmitted through fecal-oral route and zoonotic transmission. Hepatitis is a main health care problem in Turkey; HBV and HCV prevalences are 4 and 1% respectively. Hepatitis D represents another considerable hepatitis etiology with a prevalence of 5-27%...

Extraintestinal infection with Clostridium difficile has been reported but remains uncommon. Treatment of this unusual complication is complex given the limitations of current therapeutic options. Here we report a novel case of recurrent extraintestinal C. difficile infection that occurred following fecal microbiota transplantation. Using whole genome sequencing, we confirmed recrudescence rather than reinfection was responsible. The patient ultimately responded to prolonged, targeted antimicrobial therapy informed by susceptibility testing...
