A species of ordinary gut bacteria that we all carry flourishes when the intestinal flora is knocked out by a course of antibiotics.

Flagella are the main motility structure of Clostridioides difficile that affects the adhesion, colonization, and virulence of C. difficile in the human gastrointestinal tract. The FliL protein is a single transmembrane protein bound to the flagellar matrix. This study aimed to investi …

Infectious colitis is inflammation of the intestines resulting from an underlying bacterial, viral, or parasitic infection. Learn more here.

Excellent talk at #DDW2023 by Dr. ⁦@CTropini⁩ on creating a healthy gut microbiome environment. You wouldn’t “plant trees during a forest fire”. We need to create the gut environment (e.g pH, osmolality) to increase survival of #FMT treatment. ⁦@getgutsycanada⁩ pic.twitter.com/CNfspRloX4— Kate Lee (@KateLeeIBD) May 9, 2023

Heithoff et al. observe that antibiotic testing in cell culture medium improves the accuracy by which laboratory testing predicts clinical outcomes in mice. Test methods with increased diagnostic accuracy will address the antimicrobial resistance crisis by improving the way antibiotics are developed, tested, and prescribed.

Crohn's disease (CD) is a type of inflammatory bowel disease (IBD) characterized by chronic transmural inflammation of any portion of the gastrointestinal tract. The etiology of CD remains unknown although genetic, immunological, and acquired factors have been recognized as contributing to its devel …

The intestinal microbiota is the set of bacteria and viruses that live inside your gut. Microbiota perform a variety of functions, including digesting food and protecting against specific pathogens.

Objective: We analyze the characteristics of Clostridioides difficile (C. difficile) infection among diarrhea patients in Kunming from 2018 to 2020 and provide evidence for follow-up surveillance and prevention. Methods: A total of 388 fecal samples of diarrhea patients f …

The Gut Microbiome Conference has become a successful event for keeping healthcare professionals and scientists informed about the latest advances in human microbiome science. Now in its 4th year, this one-of-a-kind platform provides attendees the opportunity to interact with the leading authorities on gut microbiome r

Immune checkpoint inhibitors (ICI) are commonly used for various malignancies. A particular checkpoint inhibitor is the anti-PD-1 antibody pembrolizumab. Immune-mediated diarrhea and colitis (IMDC) is the most frequently observed immune-related adverse event (irAE) involving the gastrointestinal sys …

The obligate anaerobic, enteric pathogen Clostridioides difficile persists in the intestinal tract by forming antibiotic-resistant endospores that contribute to relapsing and recurrent infections. Despite the importance of sporulation for C. difficile pathogenesis, environmental cues and molecular m …

A new study shows that the gut microbiota has little or no effect on our weight, metabolism and risk of developing chronic diseases.

Intestinal bile acids play an essential role in the Clostridioides difficile lifecycle having been shown in vitro to modulate various aspects of pathogenesis, including spore germination, vegetative growth, and more recently the action of the primary virulence determinant, TcdB. Here, we inve …

Clostridioides difficile (C. difficile) and coronavirus disease 2019 (COVID-19) infections can have overlapping symptoms. Recently, the association and outcomes of coinfection have been studied....

Clostridioides difficile, the primary cause of nosocomial antibiotic-associated diarrhea, has a complex relationship with antibiotics. While the use of broad-spectrum antibiotics disrupts the gut microbiota and increases the risk of C. difficile infection (CDI), antibiotics are also the primary trea …

Co-existing CMV colitis should be considered in patients with aggravated C. difficile infection on appropriate treatment, even in immunocompetent hosts.

We observed differences in microbiome patterns between healthy individuals, colonized patients, CDI, R-CDI, and NOCDI diarrhea. We identified possible microbiome biomarkers that could prove useful in the diagnosis of true CDI infections. Further studies are warranted.

Educational Case: Pseudomembranous colitis attributable to Clostridioides difficile

Peripartum CDI was associated with higher odds of cesarean delivery and lower odds of GBS infections. Larger studies exploring the effect of CDI on pregnancy and neonatal outcomes are needed.

Bacterial spores can survive for years, even centuries, without nutrients, resisting heat, UV radiation, and antibiotics. How inert, sleeping bacteria -- or spores -- spring back to life has been a century-long mystery. New research identifies how sensor proteins revive dormant bacteria. Discovery opens new routes to combat spore resistance to antibiotics and sterilization. Findings can inform novel strategies to prevent infections, food spoilage.

Anaerobes have developed unique metabolic pathways and strategies, some of which are still not well understood. Now, a study that integrates spectroscopy with dynamic metabolic modeling reveals the metabolism of the anaerobic pathogen Clostridioides difficile.

Clostridioides difficile is a Gram-positive, spore-forming, anaerobic bacterium. The clinical features of C. difficile infections (CDIs) can vary, ranging from the asymptomatic carriage and mild self-limiting diarrhoea to severe and sometimes fatal pseudomembranous colitis. C. diffi …

Clostridioides difficile infection (CDI) appears to be associated with different liver diseases. C. difficile secretes membrane vesicles (MVs), which may be involved in the development of nonalcoholic fatty liver disease (NALFD) and drug-induced liver injury (DILI). In this study, we i …

The anaerobic pathogen Clostridioides difficile, which is a primary cause of antibiotic-associated diarrhea, faces a variety of stresses in the environment and in the mammalian gut. To cope with these stresses, alternative sigma factor B (σsupB/sup) is employed to modulate gene transcription, an …

Clostridioides difficile pathogenesis is mediated through its two toxin proteins, TcdA and TcdB, which induce intestinal epithelial cell death and inflammation. It is possible to alter C. difficile toxin production by changing various metabolite concentrations within the extracellular environment. H …

Clostridioides (Clostridium) difficile in the environment is thought to contribute to C. difficile infection in community settings. Here, we provide complete genome assemblies for two esculin hydrolysis-negative strains of C. difficile that were isolated from soils in Western Australia; the strains …
