Clostridioides difficile is a spore-forming anaerobic Gram-positive bacterium responsible for a broad spectrum of intestinal symptoms and healthcare associated diarrhoea. The hypothesis of this work was that different in vitro conditions, notably pH and human faecal microbiota composition impact the …

Communications Biology - Clostridium novyi alpha-toxin (Tcnα) also uses LRP1 and Megalin as cellular entry receptors besides LDLR, and this might be a response to cell-type dependent receptor...

Clostridioides difficile is a Gram-positive bacillus, which is a frequent cause of gastrointestinal infections triggered by the depletion of the gut microbiome. Because of the frequent recurrence of these infections after antibiotic treatment, mechanisms of C. difficile persistence and recurrence, i …

Nature Microbiology - Characterization of a biosynthetic pathway for the sulfonation of steroidal metabolites, such as cholesterol, by gut bacteria may have implications for immune cell trafficking...

A gastroenterologist, Dr. Bincy Abraham, provides an overview of C. difficile infection (CDI) in patients with inflammatory bowel disease (IBD).

Clostridioides difficile infection (CDI) is the leading cause of antibiotic-associated intestinal disease, resulting in severe diarrhea and fatal pseudomembranous colitis. TcdB, one of the essential virulence factors secreted by this bacterium, induces host cell apoptosis through a poorly understood …

When compared to those without IBD, patients with IBD have a reduced proportion of cases of C. difficile with toxin positivity. Differences in clinical outcomes among patients with IBD were not detected and limited by the infrequent detection of expressed toxin.

Although this study does not support the claim that Clostridium difficile and/or H. pylori have a role in UC, it greatly suggests that pathogenic E. coli may be involved in one way or another in the course of UC.

Toxins TcdA and TcdB from Clostridioides difficile glucosylate human colon Rho GTPases. TcdA and TcdB glucosylation of RhoGTPases results in cytoskeletal changes, causing cell rounding and loss of intestinal integrity. Clostridial toxins TcdA and TcdB are proposed to catalyze glucosylation of …

Clostridium difficile (C. difficile) is a multi-strain, spore-forming, Gram-positive, opportunistic enteropathogen bacteria, majorly associated with nosocomial infections, resulting in severe diarrhoea and colon inflammation. Several antibiotics including penicillin, tetracycline, and …

Clostridioides difficile (C. difficile) is a Gram-positive, spore-forming, toxin-producing, obligate anaerobic bacterium. C. difficile infection (CDI) is the leading cause of health-care-associated infective diarrhea. The infection is mediated by the spore, a metabolically inact …

The patient-derived Clostridioides difficile bacterial strain was found to drive colon tumorigenesis through its toxin TcdB, which induced Wnt signaling and a protumorigenic mucosal immune response.

Clostridioides difficile is an important health care-associated pathogen. The aim of this study was to analyze the antibiotic susceptibility of C. difficile isolates from feces of patients from 13 hospitals in Silesia, Poland. The incidence of CDI per 100.000 people in Silesia in 2018- …

Clostridioides (Clostridium) difficile infection (CDI) is an evolving global healthcare problem, and owing to the diverse and dynamic molecular epidemiology of C. difficile, new strains continue to emerge. In Brazil, only two cases of CDI due to the so called hypervirulent PCR ribotype (RT) 027 belo …

Clostridioides difficile is the major pathogen of pseudomembranous colitis, and novel antimicrobial agents are sought after for its treatment. Phage-derived endolysins with species-specific lytic activity have potential as novel antimicrobial agents. We surveyed the genome of C. difficile …

C. difficile enterocolitis (CDAC) is the most common hospital infection, burdened by an increased incidence of coagulation-related complications such as deep vein thrombosis (DVT) and disseminated intravascular coagulation (DIC) as well as a significant sepsis-related mortality. In this revie …

The role of fungal colonizers of the gastrointestinal tract during disease states is not well understood. Antibiotic treatment renders patients highly susceptible to infection by the bacterial pathogen C. difficile while also leading to blooms in fungal commensals, setting the stage for trans-kingdo …

Inflammatory bowel disease (IBD), comprising Crohn's disease and ulcerative colitis, is a chronic inflammatory condition of the gastrointestinal tract, which is often accompanied by altered gut microbial composition. Gut dysbiosis in IBD is considered to be the reason for the high risk of Clostri …

The incidence of CDC in lower extremity orthopedic trauma patients was 0.71%. An occurrence of CDC was associated with approximately a 2.5 times increase in 30-day mortality, five times the readmission rate, and a longer hospital stay compared to patients without CDC. Mitigating the spread of c. dif …

This is a case of lethal acute diarrhea associated with a mild neutrophilic enteritis in a buffy-tufted-ear marmoset (Callithrix aurita) with detection of A/B toxins and isolation of a toxigenic clade 3 Clostridioides difficile strain (A+ B+ CDT+ , ST5), which should …

As a marker of inflammation, calprotectin has potential application value in a variety of inflammatory diseases, such as arthritis and bacterial infections. Clostridioides difficile infection (CDI) is an infectious disease that causes intestinal damage and inflammation. This systematic review …

Bacterial AB-type toxins are proteins released by the producing bacteria and are the causative agents for several severe diseases including cholera, whooping cough, diphtheria or enteric diseases. Their unique AB-type structure enables their uptake into mammalian cells via sophisticated mecha …
