Can the immune response to COVID-19 trigger inflammatory bowel disease?

The outer coat of the antibiotic-resistant bacterium Clostridium difficile has a structure similar to chain mail that stops drugs and immune system cells from killing it

The spectacular structure of the protective armor of superbug C.difficile has been revealed for the first time showing the close-knit yet flexible outer layer – like chain mail.

Clostridioides difficile is a major nosocomial pathogen that can cause severe, toxin-mediated diarrhea and pseudomembranous colitis. Recent work has shown that C. difficile exhibits heterogeneity in swimming motility and toxin production in vitro through phase variation by site- …

“#Cdiff is considered to be a #pathogen, but our data suggests that it is a common #commensal in healthy #infants. How we label cdiff matters, because it can affect our perception of the species 🦠 and how we decide to investigate it 🔎“

Clostridioides difficile is a Gram-positive, spore-forming obligate anaerobe and a major threat to the healthcare system world-wide. Because of its strict anaerobic requirements, the infectious and transmissible morphotype is the dormant spore. During infection, C. difficile produces spores that can …

Clostridioides difficile infection (CDI) is the leading cause of nosocomial diarrhea and pseudomembranous colitis in the USA. In addition to these symptoms, patients with CDI can develop severe inflammation and tissue damage, resulting in life-threatening toxic megacolon. CDI is mediated by two larg …

@AJMC_Journal and #Cdiff experts recently discussed the impact #rCDI can have on a #patient. Click here to watch their discussion: https://t.co/1zABGYbYGK pic.twitter.com/Nq6xYqmxXp— Rebiotix Inc. (@Rebiotix) February 15, 2022

Clostridioides difficile is a pathogen often associated with hospital-acquired infection or antimicrobial-induced disease; however, increasing evidence indicates infections can result from community or environmental sources. Most genomic sequencing of C. difficile has focused on clinic …

The gastrointestinal tract (GIT) is considered the largest immunological organ, with a diverse gut microbiota, that contributes to combatting pathogens and maintaining human health. Under physiological conditions, the crosstalk between gut microbiota and intestinal epithelial cells (IECs) plays a cr …

Clostridioides difficile, an intestinal pathogen and leading cause of nosocomial infection, exhibits extensive phenotypic heterogeneity through phase variation. The signal transduction system CmrRST, which encodes two response regulators (CmrR and CmrT) and a sensor kinase (CmrS), impacts C. diffici …

The gut microbiome is an ecosystem of hundreds to thousands of microbial species living within the human body. These populations affect our health, fertility, and even our longevity. But how do they

Patients with fecal samples that were positive for CDT had increased disease severity and worse clinical outcomes. Utilization of PCR and testing for C. difficile toxins A and B may not reveal the entire picture when diagnosing CDI; detection of CDT-expressing strains is valuable in identifyi …

The partners hope that metabolic profiles of carriers of disease-associated genetic variants may offer insights into the basic biology of disease processes.

The first time I had a Clostridioides difficile infection, I was 37 years old. After a sequential antibiotic cocktail of amoxicillin, penicillin, metronidazole, and clindamycin prescribed to combat an infection in my jaw, I had the first wave of symptoms. Even having a long history of stomach-related issues dating back to my childhood, these new symptoms were like nothing I had ever experienced. Anything I consumed quickly traversed my gastrointestinal system within an impressively short timeframe, leaving me with a feeling of perpetual emptiness and exhaustion, a heightened awareness of the nearest restroom facilities, and an existential appreciation for saltine crackers.

The Microbiome Health Index for post-Antibiotic dysbiosis was a promising biomarker for predicting antibiotic dysbiosis and subsequent microbiome restoration, according to research published in Frontiers of Microbiology. “It’s very important that we maintain a healthy microbiome, but there are things that can disrupt or perturb a healthy microbiome to a less healthy state, which we

In COVID-19 there is bacterial and fungal dysbiosis that correlates with systemic and pulmonary inflammation, and illness severity. Further investigations are warranted to determine the efficacy of bacteriotherapy and FMT for modulating gut dysbiosis in COVID-19.

Clostridioides difficile is a leading cause of the healthcare-associated disease C. difficile infection (CDI), which has an annual US burden of over 200 000 cases. CDI mitigation strategies have been complicated by the emergence, and widespread distribution, of phylogenetically diverse lineages, as …

Investigators conducted a study that assessed disease severity and outcomes in patients with Clostridioides difficile infection with C difficile binary toxin-expressing strains.

Infections by the pathogenic gut bacterium Clostridioides difficile cause severe diarrheas up to a toxic megacolon and are currently among the major causes of lethal bacterial infections. Successful bacterial propagation in the gut is strongly associated with the adaptation to changing nutrition-cau …

Both single-donor and multiple-donor fecal microbiota transplantation had clinical cure rates over 80%.

Background: Within eight weeks of primary Clostridioides difficile infection (CDI), as many as 30% of patients develop recurrent disease with the associated risks of multiple relapses, morbidity, and economic burden. There are no clear clinical correlates or validated biomarkers …

We found no association between obesity and death among patients with CDI, in contrast to most other infections. Obesity is not likely to be useful for risk-stratifying hospitalized patients with CDI.

CDI in pediatric patients with AP is associated with adverse clinical outcomes and increased healthcare resource utilization. Further studies are needed to elucidate this association to prevent the development of CDI and to improve outcomes.

In a Healio video exclusive, Ruchi Mathur, MD, of the Medically Associated Science and Technology Program at Cedars-Sinai in Los Angeles, discussed how the aging process is associated with changes to the small intestinal microbiome. Mathur and colleagues studied duodenal aspirates in 251 patients, aged 18 to 80 years, and observed decreased microbial diversity in older patients, driven by

Clostridioides difficile infection (CDI) imposes a substantial burden on the health care system in the United States. Understanding the biological basis for the spectrum of C. difficile-related disease manifestations is imperative to improving treatment and prevention of CDI. Here, we …

The composition of the gut microbiome is "strongly" linked with long-COVID symptoms months after a person recovers from their initial infection, a new study shows.
