Based on the observed responses to C. difficile challenge, we concluded for the first time that the Mongolian gerbil could be used as an animal model for CDI. Additionally, the taxa identified in this study may be used as biomarkers for further studies on CDI and to improve understanding rega …

Recent advances in sequencing technologies have led to an explosion of studies associating the human microbiome with the risk and severity of infectious diseases. As our knowledge of the extent to which the microbiome influences childhood infections continues to grow, microbiome-based diagnostics an …

Genomic data suggested that resistance to therapeutic antimicrobial drugs is rare in C. difficile. Public antimicrobial resistance marker databases were not equipped to detect most of the genetic determinants relevant to antibiotic therapy of CDI.

Antibiotic-induced dysbiosis is a major risk factor for Clostridioides difficile infection (CDI), and fecal microbiota transplantation (FMT) is recommended for treating CDI. However, the underlying mechanisms remain unclear. Here, we show that Tritrichomonas musculis (T.mu), an integral member of th …

Patients with iCDI who are older, on hemodialysis, or had recent hospitalization or nitrofurantoin use had increased risk of mrCDI and may benefit from early use of adjunctive therapy to prevent mrCDI. If confirmed, these findings could aid in clinical decision making and interventional study design …

The global pathogen Clostridioides difficile is a well-studied organism, and researchers work on unraveling its fundamental virulence mechanisms and biology. Prophages have been demonstrated to influence C. difficile toxin expression and contribute to the distribution of advantageous g …

A mára ritkán előforduló tuberkulózis (tbc) extrapulmonális manifesztációi előrehaladott rosszindulatú daganatok képét utánozhatják, jelentős diagnosztikus dilemmákat okozva. A tbc igazolása gyakorta bonyolult, komplex vizsgálatokat igényel. Egy fiatal vietnámi nőbeteg esetét ismertetjük, aki idült …

Study in mice could lead to better treatment and prevention for humans.

Clostridioides difficile (C. diff) is a leading cause of diarrhea and healthcare-associated infections in the United States and recognized as an urgent threat by the Centers for Disease Control. Virulence of C. diff infections is believed to rely primarily on the production of two toxins: TcdA and TcdB. TcdA and TcdB are large homologous proteins...

Nature Communications - Faecal microbiome transplant has been shown to be able to reduce Clostridioides difficile infection. Here the authors show that an intestinal commensal protozoan reduces C....

Clostridioides difficile , the leading cause of antibiotic-associated diarrhea, relies primarily on 3-3 crosslinks created by L,D-transpeptidases (LDTs) to fortify its peptidoglycan (PG) cell wall. This is unusual, as in most bacteria the vast majority of PG crosslinks are 4-3 crosslinks, whi …

The gut microbiota influences anti-tumor immunity and can induce or inhibit response to immune checkpoint inhibitors (ICIs). Therefore, microbiome features are being studied as predictive/prognostic biomarkers of patient response to ICIs, and microbiome-based interventions are attractive adjuvant tr …

Late anti-toxin-B humoral immunity acquired after treatment is important for preventing recurrent Clostridioides difficile infection. We prospectively-measured anti-toxin-B IgG and neutralization titers at diagnosis as potential early predictors of recurrence. High anti-toxin-B-IgG/neutralizing anti …

Clostridioides (Clostridium) difficile is an enteric pathogen of several mammalian species including man, frequently involving nosocomial resurgence, following oral administration of broad-spectrum antibiotics, but also with human-to-human infection occurring, and neonatal pigs …

Although the role of the intestinal microbiota in the pathogenesis of inflammatory bowel disease (IBD) is beyond debate, attempts to verify the causative role of IBD-associated dysbiosis have been limited to reports of promoting the disease in genetically susceptible mice or in chemically induced co …

A C. difficile infection prior to THA is an independent risk factor for PJI. Proximity of C. difficile infection is associated with increased risk of PJI. Future investigations should evaluate how to adequately optimize patients prior to THA and pursue strategies to determine appropriate timing for …

This study shows a statistically significant correlation between CDI and decreased incidence of CRC. Additionally, there is a statistically significant correlation between obese patients with CDI and an increased incidence of CRC. Further research is needed to explore the mechanism of this striking …

In conclusion, post-infection intestinal dysfunction occurs in humans and mice post-CDI. Importantly, we have validated in the mouse model that CDI causes abnormal GI transit in the recovery phase of the disease, indicating the potential utility of the model in exploring the underlying mechanisms of …

Incidence and risk factors of Clostridioides difficile infection in liver transplant recipients: A comprehensive literature review

Dr. Joy Scaria, OSU’s Walter R. Sitlington Endowed Chair in Infectious Diseases, has been awarded a $385,000 U.S. Department of Agriculture grant to investigate microbiome-targeted interventions for swine gastric disorders over three years.

Takotsubo Syndrome and Colitis Due to Clostridium difficile: Is There a Relationship?

Clostridioides difficile is a leading cause of antibiotic-associated gastrointestinal illness, and many disease pathologies are caused by the toxin TcdB. TcdB engages multiple cell surface receptors, with receptor tropisms differing among the variants of the toxin. Chondroitin sulfate proteog …

BBR alleviated concanavalin A-induced AIH by modulating the gut microbiota and related immune regulation. These results shed more light on potential BBR therapeutic strategies for AIH.

Scientific Reports - Clostridium butyricum enhances colonization resistance against Clostridioides difficile by metabolic and immune modulation

Aim: The bacterial microbiota is well-recognized for its role in Clostridioides difficile colonization and infection, while fungi and yeasts remain understudied. The aim of this study was to analyze the predictive value of the mycobiota and its interactions with the bacterial microbiot …

A Severe Infection Caused by a White Colony-Producing Strain of Clostridioides difficile RTC41/ST588

Clostridium difficile (C. difficile) is a Gram-positive, spore-producing bacterium that often leads to pseudomembranous colitis, typically manifesting as watery diarrhea. The risk factors for C. difficile infection (CDI) include exposure to broad-spectrum antibiotics, immunocomp …

A 50-year-old female who presented to our hospital for recurrent diarrhea was found to have worsening aminotransferase and alkaline phosphatase levels. Workup revealed lymphadenopathy and hepato...
