Further clinical research is warranted to identify effective interventions for preventing and controlling CDI durin …
Significant drop in serum C-reactive protein in patients with solid neoplasia and bacterial infection is associated with a better prognosis and identifies candidates for short-course antibiotic therapy - PubMed
In this study, cancer patients with a good CRP response during antibiotic therapy presented lower mortality and a higher proportion of satisfactory therapeutic responses. CRP can be a useful tool when combined with other clinical information in optimizing the duration of antimicrobial treatment in a …
The DAV132 colon-targeted adsorbent does not interfere with plasma concentrations of antibiotics but prevents antibiotic-related dysbiosis: a randomized phase I trial in healthy volunteers
Nature Communications - The oral antibiotic adsorbent DAV132 can reduce fecal concentrations of antibiotics while preserving their pharmacokinetic properties. Here, in a randomized trial in healthy...
The Impact of YabG Mutations on Clostridioides difficile Spore Germination and Processing of Spore Substrates - PubMed
YabG is a sporulation-specific protease that is conserved among sporulating bacteria. Clostridioides difficile YabG processes the cortex destined proteins preproSleC into proSleC and CspBA to CspB and CspA. YabG also affects synthesis of spore coat/exosporium proteins CotA and CdeM. In prior work th …
Recent data and conversations with experts highlighted the increasing concern of Long COVID’s impact on the brain in patients who have been previously infected with the virus.
Structure-Activity Relationship of Inositol Thiophosphate Analogs as Allosteric Activators of Clostridioides difficile Toxin B - PubMed
Clostridioides difficile is a bacterium that causes life-threatening intestinal infections. Infection symptoms are mediated by a toxin secreted by the bacterium. Toxin pathogenesis is modulated by the intracellular molecule, inositol-hexakisphosphate (IP6). IP6 binds to a cysteine protease do …
Mice colonized with the defined microbial community OMM19.1 are susceptible to C. difficile infection without prior antibiotic treatment - PubMed
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 C. difficile to colonize the intestine. The Oligo Mouse Microbiota 19.1 …
Virulence factors, antibiotic susceptibility and sequence type distribution of hospital-associated Clostridioides difficile isolates in Israel, 2020-2022 - PubMed
Biofilm formation and toxin production are some of the virulence factors of Clostridioides difficile (C. difficile), which causes hospital-acquired C. difficile infection (HA-CDI). This work investigated the prevalence and distribution of different strains recovered from HA-CDI patients hospitalized …
Virulence factors, antibiotic susceptibility and sequence type distribution of hospital-associated Clostridioides difficile isolates in Israel, 2020–2022
Scientific Reports - Virulence factors, antibiotic susceptibility and sequence type distribution of hospital-associated Clostridioides difficile isolates in Israel, 2020–2022
Sex hormones modulate the immune system to influence disease risk differently | Imperial News | Imperial College London
IMMUNE INSIGHTS - Researchers have uncovered how hormones profoundly affect our immune systems, explaining why men and women are affected by diseases differently.
Interplay between Bile Acids and Intestinal Microbiota: Regulatory Mechanisms and Therapeutic Potential for Infections - PubMed
Bile acids (BAs) play a crucial role in the human body's defense against infections caused by bacteria, fungi, and viruses. BAs counteract infections not only through interactions with intestinal bacteria exhibiting bile salt hydrolase (BSH) activity but they also directly combat infections. Buildin …
Clinical sequelae of gut microbiome development and disruption in hospitalized preterm infants - PubMed
Aberrant preterm infant gut microbiota assembly predisposes to early-life disorders and persistent health problems. Here, we characterize gut microbiome dynamics over the first 3 months of life in 236 preterm infants hospitalized in three neonatal intensive care units using shotgun metagenomics of 2 …
The small acid-soluble proteins of Clostridioides difficile regulate sporulation in a SpoIVB2-dependent manner - PubMed
Clostridioides difficile is a pathogen whose transmission relies on the formation of dormant endospores. Spores are highly resilient forms of bacteria that resist environmental and chemical insults. In recent work, we found that C. difficile SspA and SspB, two small acid-soluble proteins (SASPs), pr …
Retrospective, Propensity Score Matched Study Examining Relationship between Frailty and Clostridioides difficile Infection in a National Cohort of United States Veterans - PubMed
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.
Elucidating human gut microbiota interactions that robustly inhibit diverse Clostridioides difficile strains across different nutrient landscapes - PubMed
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 …
Damon Runyon Cancer Research Foundation awards $4.8 million to exceptional early-career scientists
“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.”
For C. diff, antibiotic resistance comes at a cost
Researchers have identified two distinct mechanisms of drug resistance in C. difficile, but its ability to withstand antibiotics comes with downsides for the bacteria.
