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.

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

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 …

Some research has shown an association between flooding, which is becoming more common with climate change, and Clostridioides difficile infections.

Similarities between the symptoms of Clostridioides difficile infection and Crohn disease may cause confusion for health care providers.

Solution to long-standing mystery of bacterial spores illuminates new paths for disease prevention

Clostridium difficile frequently causes an infectious disease known as Clostridium difficile infection (CDI) and there are urgent needs for the development of more effective rapid diagnostic tests for CDI. Previously we have developed an RNA-cleaving fluorogenic DNAzyme (RFD) probe named RFD-CD1, wh …

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 unkno...

S-Adenosyl-l-methionine (SAM) analogs are adaptable tools for studying and therapeutically inhibiting SAM-dependent methyltransferases (MTases). Some MTases play significant roles in host-pathogen interactions, one of which is Clostridioides difficile-specific DNA adenine MTase (CamA). …

The etiologies of short bowel syndrome (SBS) can be stratified into congenital or acquired etiologies, with the latter being more prevalent. Small intestinal surgical resection is the most commo...

Fluorescence microscopy is a valuable tool to study a broad variety of bacterial cell components and dynamics thereof. For Clostridioides difficile, the fluorescent proteins CFPsupopt/sup, mCherrysupOpt/sup and phiLOV2.1, and the self-labelling tags SNAPsupCd/sup and HaloTag, hereafter c …

On April 24th, @PeggyFund will host the 2023 National C. diff Advocacy Summit. During the event #CDiff patients, caregivers and healthcare industry members will discuss their experiences and strategies to fight this potentially life-threatening disease. https://t.co/WMnMENqxvp— MTIG (@MTIG_News) April 19, 2023

Clostridioides difficile is a spore-forming human pathogen responsible for significant morbidity and mortality. Infections by this pathogen ensue dysbiosis of the intestinal tract, which lead to germination of the spores. The process of spore formation requires a transition for the cell-wall peptido …

Draft genome sequences of five Clostridioides difficile clinical isolates were obtained in Florida, USA. Three isolates, designated TGH29 (sequence type 1 [ST1]/clade 2), TGH79 (ST11/clade 5), and TGH91 (ST35/clade 1), contained toxin-encoding genes. The two nontoxigenic strains were classified as T …

Formstack Form - CLO2309

As many gastro-intestinal pathogens, the majority of Clostridioides difficile strains express flagella together with a complete chemotaxis system. The resulting swimming motility is likely contributing to the colonization success of this important pathogen. In contrast to the well investigate …
