Immune-related colitis is associated with fecal microbial dysbiosis and can be mitigated by fecal microbiota transplantation - PubMed
Colitis induced by treatment with immune checkpoint inhibitors (ICI), termed irColitis, is a substantial cause of morbidity complicating cancer treatment. We hypothesized that abnormal fecal microbiome features would be present at the time of irColitis onset, and that restoring the microbiome with f …

Treatment of preterm brain injury via gut-microbiota-metabolite-brain axis - PubMed
This review summarizes mechanisms underlying microbiota-gut-brain axis and novel therapeutic opportunities for neurological sequelae in preterm infants. Optimizing the initial colonization and microbiota development in preterm infants may represent a novel therapy to promote brain development and re …
The Changes in Broad-spectrum Antimicrobial Consumption during the COVID-19 Pandemic in a Japanese Acute Tertiary-care Hospital: An Interrupted Time-series Analysis - PubMed
Objective The novel coronavirus disease 2019 (COVID-19) pandemic has spread worldwide, and hospitals in Japan have been forced to respond to the situation. This study evaluated the broad-spectrum antimicrobial use before and during the COVID-19 pandemic in an acute tertiary-care hospital. Methods Th …
Genomic surveillance of Clostridioides difficile transmission and virulence in a healthcare setting - PubMed
Clostridioides difficile infection (CDI) is a major cause of healthcare-associated diarrhea, despite the widespread implementation of contact precautions for patients with CDI. Here, we investigate strain contamination in a hospital setting and genomic determinants of disease outcomes. Across …
C. diff linked to contaminated hospital beds, study finds
Make sure to disinfect beds properly after they are used by someone with Clostridioides difficile, or C. diff. According to a new study, staying in a bed previously used by a person with C. diff raises the risk that they’ll get the infection.
Update on Microbiota-derived therapies for recurrent Clostridioides difficile infections, 2023 - PubMed
Stool-derived products and bacterial consortia need to be clearly distinguished in terms of product characterization and their associated risks with specific long-term post-marketing evaluation similar to registries used for FMT. Their place in the therapeutic strategy for patients with rCDI require …
Bacteroides acidifaciens and its derived extracellular vesicles improve DSS-induced colitis - PubMed
Therefore, B. acidifaciens and its derived EVs can alleviate DSS-induced colitis by reducing mucosal damage to colon tissue, reducing inflammatory response, promoting mucosal barrier repair, restoring gut microbiota diversity, and restoring gut microbiota balance in mice. The results of this …
Butyrate Protects against Clostridium difficile Infection by Regulating Bile Acid Metabolism | Microbiology Spectrum
Here, we show that levels of fecal short-chain fatty acids (SCFAs), particularly butyrate, are reduced, and normal colon structure is damaged in patients with CDI compared with those in healthy individuals. Bile acid (BA) metabolic disorder in patients ...
New treatment for recurrence of C. difficile infection approved by FDA
The FDA approved VOWST to prevent recurrence of C. difficile infection. The approval is based on a trial in which UC Davis Health’s Stuart Cohen served as principal investigator.
Intestinal bile acids provide a surmountable barrier against C. difficile TcdB-induced disease pathogenesis | Proceedings of the National Academy of Sciences
Intestinal bile acids play an essential role in the Clostridioides difficile lifecycle having been shown in vitro to modulate various aspects of pa...
Mass General Brigham Researchers Identify New Strategies to Treat C. difficile Infections | Mass General Brigham
A team of investigators from Mass General Brigham’s founding members, Brigham and Women’s Hospital and Massachusetts General Hospital, has identified metabolic strategies used by Clostridioides difficile to rapidly colonize the gut and new treatments for it.
Budesonide, an anti-inflammatory drug, exacerbate clostridioides difficile colitis in mice
Clostridioides difficile infection (CDI) induces intense acute inflammatory responses through toxin release. A combination of antibiotic and anti-infl…
Glycine fermentation by C. difficile promotes virulence and spore formation, and is induced by host cathelicidin | Infection and Immunity
Clostridioides difficile is an anaerobic, Gram-positive, spore-forming gastrointestinal pathogen that causes severe diarrheal disease which can lead to death (1). To cause disease, C. difficile spores must be ingested and germinate in the intestine upon exposure to bile salts and glycine (2). Upon the outgrowth of spores into vegetative cells, C. difficile colonizes the colon, using the available nutrients to replicate within the host. As the population increases and nutrients become scarce, C. difficile produces toxins (TcdA and TcdB), releasing additional nutrients and further altering the metabolic environment (3). In turn, host inflammation is induced, resulting in the release of immune effectors and the characteristic pathologies associated with C. difficile infections (4).
In vivo commensal control of Clostridioides difficile virulence
Leveraging systems biology approaches, we illustrate how metabolically distinct species of Clostridia protect against or worsen Clostridioides diffici…
Shengjiang Xiexin decoction mitigates murine Clostridium difficile infection through modulation of the gut microbiota and bile acid metabolism
The overuse of antibiotics has resulted in Clostridium difficile infection (CDI) as a significant global public health concern. Studies have shown tha…
Contaminated beds linked to increased risk of hospital-onset C diff infections
A study of more than 25,000 hospitals encounters found that staying in a hospital bed that previously had a patient with C diff was associated with an increased risk of hospital-onset CDI.
Navigating C. Diff During the COVID-19 Pandemic, The Impact of Antibiotic Usage and Surgeries
Feldman details her experience with C. diff, how the COVID-19 pandemic slowed the timeline of care, and how her surgical history and the use of antibiotics played into the disease’s onset.
Removing Stigma of C. Diff Can Provide Opportunities for Discussion, Developing Treatment Options
Feldman, who previously had C. diff, urges individuals to begin having conversations to help remove the stigma of the disease and raise awareness of its prevalence.
