Microbiome expands the genetic and functional capacity of its human host. Susan Lynch explains that human microbiome develops early in life and that gut microbes shape immune function and relate to disease outcomes in childhood. She also explores next-generation microbiome therapeutics and research. Recorded on 11/07/2019.

A perforated colon is one possible complication of this severe form of UC. Here’s how to get treated before it comes to that.

Enteric pathogens increase C difficile virulence by providing amino acids that shape the metabolic environment in the gut.

Nature Reviews Microbiology - This study reports that Enterococcus species can remodel the metabolic environment in the gut and reprogramme the metabolism of Clostridioides difficile, enhancing its...

Background Hormonal, biochemical, and metabolic changes after menopause may alter the quality of life of women, leading to vasomotor, psychological, and genitourinary symptoms, and changes in their gut microbiota, which regulates estrogen levels through the estroboloma. Fecal samples were used to investigate the changes in the gut microbiota during aging and hormonal changes in women. A balanced gut microbiota has been associated with health or disease conditions and remains poorly understood after menopause. This study identified the fecal microbiota, and their association with biochemical and hormonal parameters of a cohort of women in the climacteric in the city of Ouro Preto—MG, Brazil. Methods A total of 102 women aged 40 to 65 years old were recruited and distributed into three groups according to the STRAW criteria for reproductive stage: reproductive (n = 18), premenopausal (n = 26), and postmenopausal (n = 58). Blood samples were collected to measure their serum biochemical and hormone levels, and the participants answered a questionnaire. The gut microbiota was analyzed from fecal samples by qPCR using the genera Bifidobacterium, Bacteroides, Lactobacillus, and Clostridium. Results The following parameters showed differences among the groups: total cholesterol, triglycerides, VLDL, ApoB, urea, calcium, uric acid, and alkaline phosphatase (p

Clostridioides difficile is a major causative pathogen of nosocomial antibiotic-associated diarrhea and severe colitis. Despite the use of vancomycin and fidaxomicin as standard drugs for the treatment of C. difficile infection (CDI), clinical relapse rates remain high. Therefore, new …

Use of metronidazole for non-CDI indications within 90 days prior to diagnosis and presence of toxin A/B in stools were associated with severe CDI. Findings provide valuable insights into risk factors for severe CDI in an underserved population with cancer that warrants further exploration.

Clostridioides difficile causes antibiotic-associated diseases in humans, ranging from mild diarrhea to severe pseudomembranous colitis and death. A major clinical challenge is the prevention of disease recurrence, which affects nearly ~20 to 30% of the patients with a primary C. difficile infection …

The Clostridioides difficile pathogen is responsible for nosocomial infections. Germination is an essential step for the establishment of C. difficile infection (CDI) because toxins that are secreted by vegetative cells are responsible for the symptoms of CDI. Germination can be stimulated by the co …

Clostridioides bacteria are responsible for life threatening infections. Here, we show that in addition to actin, the binary toxins CDT, C2I, and Iota from Clostridioides difficile, botulinum, and perfrigens, respectively, ADP-ribosylate the actin-related protein Arp2 of Arp2/3 …

Nature Aging - The authors analyze microbiome profiles from several public repositories to identify the higher-level indices that best reflect the abundance and ranking of disease-associated and...

The Role of the Gut Microbiome in Clostridioides difficile Infection Introduction: A rich and diverse gut microbiome is key to immune system regulation and colonization resistance against pathogens.A disruption in the gut microbiome composition can make the gut more vulnerable t …

Join the ESNM and the AGA for the 11th annual Gut Microbiota for Health World Summit 2023. This meeting will take place in March 2023 in Prague, Czech Republic.

Clostridioides difficile is the most common cause of nosocomial antibiotic-associated diarrhoea, and is responsible for a spectrum of diseases characterised by high levels of recurrence, morbidity and mortality. Treatment is complex, since antibiotics constitute both the main treatment and th …

The aim of this study was to investigate the differences of Clostridioides difficile infection (CDI) during the COVID-19 pandemic compared to the pre-COVID-19 era. CDI patients treated at the Clinic for Infectious Diseases, Clinical Center of Vojvodina, Serbia during 2017-2019 (n = 304 …

We built a computational model of complex mechanisms at the intersection of immunity and metabolism that regulate CD4+ T cell effector and regulatory functions by using coupled ordinary differential equations. The model provides an improved understanding of how CD4+ T cells are shaping the immune re …

Only recent hospitalization and proton pump inhibitor use was deemed an independent risk factor for C difficile infections.

Redefining genomic view of Clostridioides difficile through pangenome analysis and identification of drug targets from its core genome

Hypervirulent strains of C. difficile are relevant nowadays and several issues arise from newer therapies available that need to be tackled according to @bhmullish @esnm_eu #GMFHCoverage pic.twitter.com/gueeBUsYAb— GutMicrobiota Health (@GMFHx) November 22, 2022

Study showed how Enterococcus fine tunes the environment around C. diff, restricting some nutrients and supplying others, to increase its fitness and virulence.

Study showed how Enterococcus fine tunes the environment around C. diff, restricting some nutrients and supplying others, to increase its fitness and virulence.

Children's Hospital of Philadelphia researchers found that Enterococcus, an antibiotic-resistant pathogen, works with Clostridioides difficile, or C. diff, to change the metabolic environment in the gut so C. diff can thrive, Science Daily reported Nov. 16.

The bacterium Clostridioides difficile tends to “cooperate” with microorganisms in the gastrointestinal tract, such as the pathogen Enterococcus, which can help the bacterium thrive, according to a study published in Nature.

Probiotic supplementation can help to mitigate the pathogenesis of irritable bowel syndrome (IBS) by reinforcing the intestinal barrier, and reducing both inflammation and proteolytic activity. Here, a combination of in vitro tests was performed on 33 Bifidobacterium strains as probiotic candidates …

Clostridioides difficile infection (CDI) is a gastro-intestinal (GI) infection that illustrates how perturbations in symbiotic host-microbiome interactions render the GI tract vulnerable to the opportunistic pathogens. CDI also serves as an example of how such perturbations could be reversed via gut …

Enteric pathogens are exposed to a dynamic polymicrobial environment in the gastrointestinal tract1. This microbial community has been shown to be important during infection, but there are few examples illustrating how microbial interactions can influence the virulence of invading pathoge …
