C Difficile

Clostridioides difficile is a widely distributed anaerobic pathogen. C. difficile infection is a serious problem in healthcare. Its biofilms have been found to exhibit biocorrosivity, albeit very little, but sufficient for it to correlate with biofilm growth/health. This work demonstra …

The gut microbiota represents a complex ecosystem of trillions of microorganisms residing in the human gastrointestinal tract, which is known to interact with the host physiology and regulate multiple functions. Alterations in gut microbial composition, diversity, and function are referred to as dys …

Clostridioides difficile detection in community settings is time-intensive, resulting in delays in diagnosing and quarantining infected individuals. However, with the advent of semi-automated devices and improved algorithms in recent decades, the ability to discern CDI infection from asymptom …

Background and Objectives: Clostridioides difficile infection is a major public health issue, being among the main causes of mortality due to healthcare-associated diarrhea. This study aimed to assess the trends in mortality attributable to Clostridioides difficile infections in …

This study demonstrated the potential association between baseline frailty and CDI risk and health outcomes, as well as new-onset frailty diagnoses in patients who develop CDI.

The human gut pathogen Clostridioides difficile displays substantial inter-strain genetic variability and confronts a changeable nutrient landscape in the gut. We examined how human gut microbiota inter-species interactions influence the growth and toxin production of various C. difficile strains ac …

Abstract. Clostridioides difficile (C. difficile) is a spore-forming, toxin-producing, anaerobic bacterium infecting the human gastrointestinal tract, caus

Should these challenges be tackled, a C. difficile CHIM not only provides a way forward for the testing of novel products but also offers a framework for better understanding of the pathophysiology, pathogenesis and immunology of C. difficile colonisation and infection.

New research into Parkinson's disease is strengthening the connection between an unhealthy gut and brain disorders.

Clostridioides difficile infection (CDI) has evolved to be the most significant cause of healthcare-associated diarrhoea and one of the leading representatives of healthcare-associated infections, with a high associated mortality. The aim of this retrospective study was to record the incidenc …

The certification makes the ClonoSeq assay available to EU patients and enables Adaptive to process EU clinical trial samples in its US laboratory.

“What is so exciting—and so challenging—about being a postdoc is that you’re called to take what you know and apply it to a new problem,” said Damon Runyon Fellow Georgia R. Squyres, PhD. “When you’re stepping out into open space like that, it’s important to feel that you have a net of support under you. The Damon Runyon Fellowship lets us take that leap.”

It's time to look at oral vaccines to prevent C. difficile infections, experts say

Researchers have identified two distinct mechanisms of drug resistance in C. difficile, but its ability to withstand antibiotics comes with downsides for the bacteria.

Helicobacter pylori infection has significant epidemiological relevance due to the carcinogenic nature of this bacterium, which is potentially associated with cancer. When detected, it should ideally be eradicated using a treatment that currently involves a combination of gastric acid suppres …

MP Biomedicals’ tests detect Helicobacter pylori, Salmonella typhi, and Vibrio cholerae serogroups O1 and O139.

We sought to better understand how intestinal microbiota confer protection against Clostridioides difficile (C. difficile) infection (CDI). We utilized gnotobiotic altered Schaedler flora (ASF) mice, which lack the abnormalities of germfree (GF) mice as well as the complexity and heter …

The gut pathogen Clostridioides difficile utilizes a wide range of carbon sources. Microbial communities can be rationally designed to combat C. difficile by depleting its preferred nutrients in the gut. However, C. difficile is genetically diverse with hundreds of identified ri …

Prebiotics can modulate the gut microbial community composition and function for improved (gut) health and increase resilience against infections. In vitro models of the gut facilitate the study of intervention effects on the gut microbial community relevant to health. The mucosa-associated g …

Three PF-06425090 doses were safe and well-tolerated. Although the primary endpoint was not met, PF-06425090 reduced symptom duration, CDI requiring medical attention, and CDI-directed antibiotic treatment, highlighting its potential to reduce CDI-associated healthcare burden. NCT03090191.

The Clostridia produce and secrete Large Clostridial Glucosylating Toxins (LCGTs) responsible for disease symptoms, but the secretion mechanism is largely unknown. Recently, a holin-like protein was shown to be essential for toxin secretion. Holins, typically bacteriophage-specific proteins, are par …

The gastrointestinal tract is a hypoxic environment, with the existence of two gradients of O2 along the gut, one longitudinal anteroposterior decreasing gradient and one proximodistal increasing from the lumen to the epithelial cells. O2 is a major source of stress for an obli …

Glycogen plays a vital role as an energy reserve in various bacterial and fungal species. Clostridioides difficile possesses a glycogen metabolism operon that contains genes for both glycogen synthesis and utilization. In our investigation, we focused on understanding the significance of glyc …

Nature Communications - In this paper, the authors use a systems biology approach to explore human gut microbiota interactions impacting multiple Clostridioides difficile strains in various...

Clostridioides difficile infection (CDI) has evolved to be the most significant cause of healthcare-associated diarrhoea and one of the leading representatives of healthcare-associated infections, with a high associated mortality. The aim of this retrospective study was to record the incidenc …

Clostridioides difficile infection (CDI) is a well-known cause of hospital-acquired infectious diarrhea in developed countries, though it has not been a top priority in the healthcare policies of developing countries. In the last decade, several studies have reported a wide range of CDI rates …

Pathogenic Bacillus and clostridial (i.e., Clostridium and Clostridioides) bacteria express a diverse repertoire of effector proteins to promote disease. This includes production of binary toxins, which enter host epithelial cells and seriously damage the intestinal tracts of in …

The goal of this article is to summarize common methods of antibiotic operationalization used in clinical research and demonstrate methods for exposure variable selection. We demonstrate three methods for modeling exposure, using data from a case-control study on Clostridioides difficile infection i …
