Clostridium difficile is a Gram-positive bacillus with fecal-oral transmission and is currently one of the most common nosocomial infections worldwide, which was renamed Clostridioides difficile in 2016. Clostridioides difficile infection (CDI) is a prevalent infection in cirrho …

A young female patient with a history of total colectomy developed fulminant Clostridium difficile infection of the small bowel after elective ileostomy reversal.

C. difficile infection (CDI) is a leading healthcare-associated infection with a high morbidity and mortality and is a financial burden. No current standalone point-of-care test (POCT) is sufficient for the identification of true CDI over a disease-free carriage of C. difficile, so one …

The prevalence of clinical cure was 82.9% and recurrence was 9.6% in pediatric patients receiving cancer treatments. Severe CDI, as per our proposed definition, occurred in 9.7% episodes. Initial oral vancomycin was significantly associated with a reduction in repeated new CDI episodes.

Our objective was to describe the etiologies of acute colitis and to identify patients who require diagnostic endoscopy. Patients with symptoms of gastrointestinal infection and colonic inflammation on CT were prospectively included. Those immunosuppressed, with history of colorectal cancer or infla …

The alternative sigma factor SigL (Sigma-54) facilitates bacterial adaptation to the extracellular environment by modulating the expression of defined gene subsets. A homolog of the gene encoding SigL is conserved in the diarrheagenic pathogen Clostridioides difficile. To explore the contribu …

Primary bile acids (BAs), synthesized from cholesterol in the liver, after their secretion with bile into the intestinal lumen, are transformed by gut microbiota to secondary BAs. As natural detergents, BAs play a key role in the digestion and absorption of lipids and liposoluble vitamins. However, …

Clostridioides difficile is one of the most common causes of antibiotic-associated diarrhea in developed countries. As key virulence factors of C. difficile, toxin A (TcdA) and toxin B (TcdB) act by glucosylating and inactivating Rho and Ras family small GTPases in host cells, which leads to actin c …

Background: Clostridioides difficile infection (CDI) is associated with high mortality. Clostridium butyricum MIYAIRI 588 (CBM) is a probiotic that suppresses Clostridioides difficile proliferation. We assessed the effect of a prophylactic nutritional protocol with …

The prospective, longitudinal, and multi-omic nature of our CDI recurrence study allowed us to uncover previously unrecognized dynamics in the microbiome and host presaging recurrence, and, in particular, to elucidate changes in the understudied gut metabolome. Moreover, we demonstrated that a small …

“RT @tomsandora: Happy to see this in print! Co-authored (with my friend @Larry_Kociolek) the chapter on C. difficile (my favorite bacterium…”

Objective: Comparative analyses of wild-type Clostridioides difficile 630 (Cd630) strain and pathogenicity locus (PaLoc) knockout mutant (ΔPaLoc) by using RNA-seq technology. Analysis of differential expression of Cd630 wild-type strain and ΔPaLoc mutant strain and measurement of its c …

During the past 4 decades, oral vancomycin has been a mainstay of Clostridioides difficile infection (CDI) therapy with no reports of treatment failure due to emergence of vancomycin resistance. However, C. difficile isolates with high-level phenotypic resistance to vancomycin have recently been rep …

We compiled a human metagenome assembled plasmid (MAP) database and interrogated differences across multiple studies that were originally designed to investigate the composition of the human microbiome across various lifestyles, life stages and events. This was performed as plasmids enable bacteria …

Inflammatory bowel disease (IBD), comprising Crohn's disease (CD) and ulcerative colitis (UC), is a set of clinically chronic, relapsing gastrointestinal inflammatory disease and lacks of an absolute cure. Although the precise etiology is unknown, developments in high-throughput microbial genomic se …

Clostridioides difficile (C. difficile) is a gram-positive, spore-forming, anaerobic bacterium known to be the most common cause of hospital-acquired and antibiotic-associated diarrhea. C. difficile infection rates are on the rise worldwide and treatment options are limited, indicating a clear need …

Pediatric Reactive Arthritis Due to Clostridioides difficile Infection

WGS identified a highly diverse group of C. difficile isolates among POTP with CDI. Although WGS identified clusters of closely related isolates in multiple patients, epidemiologic investigation of shared inpatient exposures identified potential transmission in only two clusters. C. difficile transm …

Children with IBD have a markedly higher incidence of CDI identified during a hospitalization relative to children without IBD. Consequently, symptomatic children with IBD who are hospitalized should be screened for CDI.An infographic is available for this article at: http://links.lww.com/MPG/C842.

Defining the complex role of the microbiome in colorectal cancer (CRC) and the discovery of novel, pro-tumorigenic microbes are areas of active investigation. In the present study, culturing and reassociation experiments revealed that toxigenic strains of Clostridioides difficile drove the tumorigen …

CAMBRIDGE, Mass., June 01, 2022--Seres Therapeutics, Inc. (Nasdaq: MCRB), a leading microbiome therapeutics company, announced the presentation of preclinical data supporting further investigation of a rationally designed microbial consortium candidate (DE486) to prevent or treat gastrointestinal (GI) mucositis – a common and often painful complication of radiation and chemotherapy involving the breakdown of the rapidly-dividing epithelial cells lining the GI tract. These results are available o

Clostridioides difficile colitis is an inflammation of the colon due to toxins produced by a gram-positive bacterium called Clostridioides difficile (also known as Clostridium difficile). Clostr...

Toxic megacolon is a serious medical condition that may require urgent care. Read on for more on the causes and treatment options.

Excellent thread @AvrahamCooperMD! We recently performed a large scale meta-analysis (42k+ metagenomic samples) looking the gut #microbiome associated with #Cdiff, especially in healthy infants!
