These findings contribute to the understanding of risk factors associated with CDI recurrence and provide support for the development of prevention strategies.

Diet, cooking, and the human microbiome

The ability to form a dormant spore is essential for the survival of the anaerobic pathogen, Clostridioides difficile, outside of the mammalian gastrointestinal tract. The initiation of sporulation is governed by the master regulator of sporulation, Spo0A, which is activated by phosphorylation. Mult …

Mucins are glycoproteins which can be found in host cell membranes and as a gelatinous surface formed from secreted mucins. Mucosal surfaces in mammals form a barrier to invasive microbes, particularly bacteria, but are a point of attachment for others. Clostridioides difficile is an anaerobi …

Nature - Insights into inflammation during infection by Clostridioides difficile.

Age, fecal calprotectin level, toxin B PCR cycle threshold, immunosuppression, sex, and creatinine levels were identified as independent risk factors for developing recurrent CDI.

There has been a decrease in healthcare-associated Clostridioides difficile infection (CDI) in Australia, coupled with an increase in the genetic diversity of strains isolated in these settings, and an increase in community-associated cases. To explore this changing epidemiology, we studied t …

C. difficile toxin strikes a nerve in the gut

[Prosthesis joint infection due to Clostridioides difficile and literature review]

Calprotectin levels and abundance of microbial genera such as Fusobacterium and Prevotella in primary episodes could be useful as early markers of R-CDI. We propose a readily available model for prediction of R-CDI that can be applied at the initial CDI episode. The use of this tool could help to be …

Clostridioides difficile (CD) is one of the most important causes of diarrhea in hospitalized patients, in particular those who undergo an allogeneic hematopoietic cell transplant (allo-HCT) and who are more at risk of developing a CD infection (CDI) due to frequent hospitalizations, iatrogenic immu …

Clostridioides difficile colonizes a polymicrobial environment in the intestine and is a causative agent for antibiotic-associated diarrhea (AAD) and pseudomembranous colitis (PMC). The most important virulence factors of C. difficile are bacterial toxins, and three toxins (toxin A, to …

Clostridioides difficile, the causative agent of antibiotic-associated diarrhea and pseudomembranous colitis, has emerged as a major enteric pathogen in recent years. Antibiotic treatment perturbs the gut microbiome homeostasis, which facilitates the colonization and proliferation of the path …

Non-toxigenic Clostridioides difficile (NTCD) has been shown to decrease the risk of recurrent C. difficile infection (CDI) in patients following metronidazole or vancomycin treatment for CDI. Limited data on the prevalence of NTCD strains in symptomatic patients and their clinical cha …

Non-toxigenic Clostridioides difficile (NTCD) has been shown to decrease the risk of recurrent C. difficile infection (CDI) in patients following metronidazole or vancomycin treatment for CDI. Limited data on the prevalence of NTCD strains in symptomatic patients and their clinical cha …

Molecular mimicry, a phenomenon in which microbial or environmental antigens resemble host antigens, has been proposed as a potential trigger for autoimmune responses. In this study, we employed a bioinformatics approach to investigate the role of molecular mimicry in Clostridioides difficile …

Clostridioides difficile, the leading cause of antibiotic-associated diarrhoea worldwide, is a genetically diverse species which can metabolise a number of nutrient sources upon colonising a dysbiotic gut environment. Trehalose, a disaccharide sugar consisting of two glucose molecules bonded …

The mammalian gut microbiome protects the host through colonization resistance (CR) against the incursion of exogenous and often harmful microorganisms, but identifying the exact microbes responsible for the gut microbiota-mediated CR against a particular pathogen remains a challenge. To address thi …

Clostridioides difficile is a leading cause of antibiotic-associated diarrheal disease. C. difficile colonization, growth, and toxin production in the intestine is strongly associated with its ability to use amino acids to generate energy, but little is known about the impact of specif …

Clostridioides difficile is a Gram-positive bacterium that can cause mild to severe diarrhea, inflammation, and colonic tissue damage in animal hosts. Symptoms of the disease can be attributed to the activity of toxin B (TcdB) secreted by C. difficile during infection. TcdB can engage …

Clostridioides difficile infection (CDI) is a major health concern and one of the leading causes of hospital-acquired diarrhea in many countries. C. difficile infection is challenging to treat as C. difficile is resistant to multiple antibiotics. Alternative solutions are needed …

Clostridioides difficile is a Gram-positive bacterium that can cause mild to severe diarrhea, inflammation, and colonic tissue damage in animal hosts. Symptoms of the disease can be attributed to the activity of toxin B (TcdB) secreted by C. difficile during infection. TcdB can engage …

Clostridioides difficile causes life-threatening gastrointestinal infections. It is a high-risk pathogen due to a lack of effective treatments, antimicrobial resistance, and a poorly conserved genomic core. Herein, we report 30 X-ray structures from a structure genomics pipeline spanning 13 y …

Clostridioides difficile is the leading cause of healthcare associated infections. The Pathogenicity Locus (PaLoc) toxins TcdA and TcdB promote host disease. These toxins lack canonical N-terminal signal sequences for translocation across the bacterial membrane, suggesting alternate mechanism …

The intestinal pathogen Clostridioides difficile encodes roughly 50 TCS, but very few have been characterized in terms of their activating signals or their regulatory roles. A. G. Pannullo, B. R. Zbylicki, and C. D. Ellermeier (J Bacteriol 205:e00164-23, 2023, https://doi.org/10.1128/jb.00164 …

The environment is a natural reservoir of Clostridioides difficile and here, we aimed to isolate the pathogen from seven locations in Northern Iraq. Four of the sites yielded thirty-one isolates (ten from soils, twenty-one from sediments) which together represent ribotypes 001 (five), 010 (five), 01 …

Hypervirulent ribotypes (HVRTs) of Clostridioides difficile such as ribotype (RT) 027 are epidemiologically important. This study evaluated whether MALDI-TOF can distinguish between strains of HVRTs and non-HVRTs commonly found in Europe. Obtained spectra of clinical C. difficile isolates (training …

A longitudinal study of ICU patients found that transition from asymptomatic C. difficile carriage to full-blown infection was far more common than transmission between patients.

The environment is a natural reservoir of Clostridioides difficile and here, we aimed to isolate the pathogen from seven locations in Northern Iraq. Four of the sites yielded thirty-one isolates (ten from soils, twenty-one from sediments) which together represent ribotypes 001 (five), 010 (five), 01 …

Clostridioides difficile infection (CDI) is a prevalent source of hospital-acquired diarrhea. The most common presentation of CDI is colitis. In cases of fulminant colitis/toxic megacolon, a colectomy and end ileostomy are part of the treatment plan. There is evidence to suggest that it may b …
