The human pathogen Clostridioides difficile has evolved into the leading cause of nosocomial diarrhea. The bacterium is capable of spore formation, which even allows survival of antibiotic treatment. Although C. difficile features an anaerobic lifestyle, we determined a remarkably high …

Along with the rise in modern chronic diseases, ranging from diabetes to asthma, lay the challenges posed by increasing antibiotic resistance resulting in difficult to treat infections, as well as sepsis. An emerging and unifying theme in the pathogenesis of these diverse public health threats is ch …

Clostridium difficile (reclassified as Clostridioides difficile [...].

Clostridioides difficile is an anaerobic pathogen that causes significant morbidity and mortality. Understanding the mechanisms of colonization resistance against C. difficile is important for elucidating the mechanisms by which C. difficile is able to colonize the gut after ant …

Our study provides specific markers of stool fungi combined with host immune factors to distinguish CDI patients from Carrier. It highlights the importance of gut mycobiome in CDI, which may have been underestimated. Further studies on the diagnostic applications and therapeutic potentials of these …

Clostridioides difficile disproportionally affects the elderly living in nursing homes (NHs). Our objective was to explore the prevalence of C. difficile in NH elders, over time and to determine whether the microbiome or other clinical factors are associated with C. difficile co …

Clostridioides difficile is the predominant antibiotic-associated enteropathogen associated with diarrhoea or pseudomembranous colitis in patients worldwide. Previously, we identified C. difficile RT078 isolates (CD21062) from elderly patients in China, including two new ribotype strai …

Clostridioides (C.) difficile is clinically highly relevant and produces several AB-type protein toxins, which are the causative agents for C. difficile-associated diarrhea and pseudomembranous colitis. Treatment with antibiotics can lead to C. difficile overgrowth in the gut of patients due to the …

Clostridioides difficile is an emerging One Health pathogen and a common etiologic agent of diarrhea, both in healthcare settings and the community. This bacterial species is highly diverse, and its global population has been classified in eight clades by multilocus sequence typing (MLST). The C. di …

Proteins seem to have an important role in the biofilm's initial adherence and maturation. slpA and cwp84 are differentially expressed by C. difficile ribotype and biofilm production level.

Neutrophils are key first-responders in the innate immune response to C. difficile infection (CDI) and play a central role in disease pathogenesis. Studies have clearly shown that tissue neutrophil numbers need to be tightly regulated for optimal CDI outcomes: while excessive colonic neutroph …

Blastocystis and Clostridioides difficile co-occurrence is considered a rare event since the colonization by Blastocystis is prevented under a decrease in beneficial bacteria in the microbiota when there is C. difficile infection (CDI). This scenario has been reported once, but no information on the …

The colonization rates of C. difficile and toxigenic C. difficile were 10% (8/80) and 3.75% (3/80), respectively. Based on the age group, the intestinal-carriage rates of C. difficile were 37.5, 50, and 12.5% in children ≤ 1, 1-3, and 3-5 years old, respectively. Our findings have revealed eight dis …

Clostridioides (C.) difficile is clinically highly relevant and produces several AB-type protein toxins, which are the causative agents for C. difficile-associated diarrhea and pseudomembranous colitis. Treatment with antibiotics can lead to C. difficile overgrowth in the gut of patients due to the …

Clostridioides difficile is the single most deadly bacterial pathogen in the United States, and its global prevalence and outsized health impacts underscore the need for more effective therapeutic options. Towards this goal, a novel group of modified peptidoglycan hydrolases with significant in vitr …

The pathogenesis of Clostridioides difficile infection (CDI) was recognized with its link to the use of antimicrobials. Antimicrobials significantly alter gut microbiota structure and composition, which led to the discovery of the association of this gut perturbation with the development of C …

The findings reveal a unique mechanism for C.diff survival in the human gut and suggest novel strategies for weakening its defenses, according to the study authors.

Microbiota changes boost a molecule that combats harmful bacteria.

Rates of serious clinical complications of Clostridioides difficile infection rose as the number of recurrent infections increased, underscoring the importance of advancing new treatments to prevent recurrence of the disease, a recent study in SAGE Open Medicine found.

Coronavirus disease 2019 is associated with a postinfectious multisystem inflammatory syndrome in children (MIS-C). This syndrome is marked by cytokine storm and multiorgan dysfunction, often affecting the gastrointestinal tract, the heart, and the hematopoietic system. We describe the case of a 16-year-old boy with an initial presentation of severe inflammatory bowel disease and concurrent MIS-C. He presented with abdominal pain, diarrhea, and hematochezia and met criteria for the systemic inflammatory response syndrome. Laboratory inflammatory profiling revealed markedly elevated ferritin...

Clostridioides difficile thrives in an environment of inflammation which found that inflammation provides nutrients for C. diff and creates an inhospitable environment for competing bacteria.

Patients with 3 or more C diff recurrences also had the highest health care resources utilization and total, all-cause, direct medical costs.

The microbiome-produced enzyme bile salt hydrolase (BSH) plays a central role in human health, but its function remains unclear due to the lack of suitable methods for measuring its activity. Here, we have developed a novel optical tool based on ultrasensitive bioluminescent imaging and demonstrated that this assay can be used for quick and cost-effective quantification of BSH activity across a broad range of biological settings including pure enzymes and bacteria, intact fecal slurries, and noninvasive imaging in live animals, as well as for the assessment of BSH activity in the entire gas...

A new study shows that the inflammation caused by Clostridioides difficile (C. diff) infection gives the pathogen a two-fold advantage: by both creating an inho

Colitis refers to the inflammation of the colon lining. There are different types of colitis that cause a range of symptoms. Learn more here.

Abdominal CT findings also predicted colitis during ICI cancer treatment

The inflammation caused by Clostridioides difficile (C. diff) infection gives the pathogen a two-fold advantage that helps it thrive, a new study shows.
