Our systematic review and meta-analysis of 40 studies (n = 3,905,559) identified gastric acid suppressants, recent hospitalization, antibiotic exposure, and certain comorbidities as independent predictors of healthcare-associated Clostridioides difficile infection (HA-CDI) among adult …

Gut microbiota-derived IAA confers a protection against SAE by activating AhR in microglia, improving neuronal and cognitive impairments. Thus, IAA holds the promise as a potential therapeutic agent for managing SAE.

This comprehensive review explores the intricate relationship between gut microbiota, diet, and insulin resistance, emphasizing the novel roles of diet-induced microbial changes in influencing metabolic health. It highlights how diet significantly influences gut microbiota composition, with differen …

The gut microbiome, an ecosystem of trillions of microorganisms in the human digestive tract, has been increasingly linked to chronic diseases

People who contracted COVID-19 during the early stages of the pandemic had an increased risk of myocardial infarction (heart attack), stroke, and death for the next 3 years, according to a study sponsored by the National Institutes of Health (NIH).

Clostridioides difficile has been recognized as an important nosocomial pathogen that causes diarrheal disease as a consequence of antibiotic exposure and costs the healthcare system billions of dollars every year. C. difficile enters the host gut as dormant spores, germinates into vegetative cells, …

Certain ribotypes, including RT 027, were the sole independent risk factors for reduced VAN susceptibility. Increased clinical surveillance of these strains, especially RT 027, and their antibiotic susceptibly is warranted to inform prescribing practices.

Prolonged hospital stay after birth is associated with infant gut dysbiosis.

Migracytosis is a recently described cellular process that generates and releases membrane-bound pomegranate-like organelles called migrasomes. Migracytosis normally occurs during cell migration, participating in various intercellular biological functions. Here, we report a new type of migracytosis …

Identifying the underlying causes of prolonged lung inflammation associated with radiographic abnormalities could be key understanding long COVID and other lung conditions, researchers say.

Cell Discovery - Bacterial toxins induce non-canonical migracytosis to aggravate acute inflammation

Clostridioides difficile strains of sequence type (ST) 37, primarily including PCR ribotype (RT) 017, are prevalent in mainland China. Our study aimed to compare the major virulence factors of an epidemic C. difficile isolate of ST37 type (Xy06) from China with the well-characterized …

Considering the bidirectional crosstalk along the gut-liver axis, gut-derived microorganisms and metabolites can be released into the liver, potentially leading to liver injury. In this editorial, we comment on several studies published in the recent issue of the World Journal of Gastroenterology …

Nature - Viruses known as bacteriophages are difficult to study, but they are beginning to give up their secrets.

The disruption of gut microbiota caused by antibiotics favors the intestinal colonization of Clostridioides difficile - a Gram-positive, spore-forming anaerobic bacterium that causes potentially fatal gastrointestinal infections. In an endeavor to elucidate the complexities of the gut-brain a …

The obligate anaerobe Clostridioides difficile encodes multiple reductases to detoxify molecular oxygen and reactive oxygen species. Caulat and colleagues have characterized the activity and regulation of four such reductases (L. C. Caulat, A. Lotoux, M. C. Martins, N. Kint, et al., mBio 15:e …

Diverse gut microorganisms present in humans and mice are essential for the prevention of microbial pathogen colonization. However, antibiotic-induced dysbiosis of the gut microbiome reduces microbial diversity and allows Clostridioides difficile (C. difficile) to colonize the intestin …

Clostridioides difficile infection (CDI) is one of the most significant causes of diarrhea in hospitalized patients. The aim of this study was to investigate the incidence and epidemiology of CDI after the COVID-19 pandemic in hospitalized patients in a rehabilitation center in Thessaloniki, Greece. …

(1) Background: We describe a model of primary mild-Clostridioides difficile infection (CDI) in a naïve host, including gut microbiota analysis, weight loss, mortality, length of colonization. This model was used in order to describe the kinetics of humoral (IgG, IgM) and mucosal (IgA) immune …

Large intestine Researchers are developing an mRNA-based vaccine for Clostridioides difficile (C. difficile), a highly contagious bacterium. C. difficile causes an infection of the colon, the longest part of the large intestine, with symptoms ranging from diarrhea to life-threatening colon damag

Patients with inflammatory bowel disease (IBD) are at increased risk of Clostridioides difficile infection (CDI). Herein, we aimed to determine if genetic risk contributes to this observed association. We carried out a genome-wide association study (GWAS) analysis in the Michigan Genomics Ini …

Despite large increases in several CDI risk factors, we did not observe the expected corresponding changes in HA-CDI rate during the first two years of the COVID-19 pandemic. We hypothesize that infection prevention measures responding to COVID-19 played a role in CDI prevention.

The results of this study demonstrated significant genetic similarity between ST11 strains isolated from environmental sampling and from animal origin; these strains may represent a reservoir for community-acquired C. difficile infection, which is becoming a growing public health threat due to the d …

Patients with inflammatory bowel disease (IBD) are at increased risk of Clostridioides difficile infection (CDI). Herein, we aimed to determine if genetic risk contributes to this observed association. We carried out a genome-wide association study (GWAS) analysis in the Michigan Genomics Ini …

Erratum for Hasan et al., "Role of glycogen metabolism in Clostridioides difficile virulence"

Clostridioides difficile is a bacterial pathogen that has been implicated in severe gastrointestinal infections. C. difficile has intrinsic green autofluorescence and the level of this autofluorescence is known to be increased by growth time and oxygen. Currently, it is unclear if diet …

Our study suggests that toxin and antitoxin genes may impact C. difficile biofilm formation, while antibiotics could signal biofilm strengthening and gene expression increase.

Many studies have demonstrated the impact of intestinal microbiota on normal brain development. Moreover, the gut microbiota (GM) is impacted by multiple endogenous and environmental factors that may promote gut dysbiosis (GD). An increasing number of studies are investigating the possible role of t …

Type 1 Diabetes Mellitus (T1DM) is a chronic autoimmune disease that results in the destruction of pancreatic β cells, leading to hyperglycaemia and the need for lifelong insulin therapy. Although genetic predisposition and environmental factors are considered key contributors to T1DM, the exact cau …
