Clostridioides difficile (C. difficile) is the predominant causative agent of nosocomial diarrhea worldwide. Infection with C. difficile occurs due to the secretion of large glycosylating toxin proteins, which can lead to toxic megacolon or mortality in susceptible hosts. A crit …

By summarizing the changes in the ocular surface and intestinal microbiota when dry eye occurs, it is speculated and concluded that the intestine may affect the occurrence of eye diseases such as dry eye through several pathways and mechanisms, such as the occurrence of abnormal immune responses, mi …

Our study is the first to demonstrate that EFD works in an OP mouse model by utilising GM and butyric acid. Thus, EF shows promise as a potential remedy for OP in the future.

Fecal microbiota transplants that alter the gut microbiome could bring relief to people with IBD who do not respond sufficiently to advanced therapies.

Clostridioides difficile is a causative agent of antibiotic-associated diarrhea as well as pseudomembranous colitis. So far, all known bacteriophages infecting these bacteria are temperate, which means that instead of prompt lysis of host cells, they can integrate into the host genome or repl …

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent type of liver disease worldwide. The exact pathophysiology behind MASLD remains unclear; however, it is thought that a combination of factors or "hits" act as precipitants for disease onset and progression. Abunda …

Unraveling the multisymptomatic Gulf War Illness (GWI) pathology and finding an effective cure have eluded researchers for decades. The chronic symptom persistence and limitations for studying the etiologies in mouse models that differ significantly from those in humans pose challenges for drug disc …

Changes in gut microbiome composition have been implicated in the pathogenesis of graft-versus-host disease (GvHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Our objective was to explore the microbial abundance in patients with GvHD after allo-HSCT. We conducted a single-c …

The U.S. Department of Health and Human Services (HHS) has awarded Virginia Tech a $300,000 grant for allergy, immunology and transplantation research related

The results suggested that the fecal propionate concentration and acetate proportion could be used as biomarkers for IBS diagnosis. A low-FODMAP diet intervention could potentially serve as a treatment for IBS while FMT and probiotic administration need more robust trials.

Nowadays, depressive disorder is spreading rapidly all over the world. Therefore, attention to the studies of the pathogenesis of the disease in order to find novel ways of early diagnosis and treatment is increasing among the scientific and medical communities. Special attention is drawn to a bioma …

Alcohol-related liver disease (ALD) is recognized as a global health crisis, contributing to approximately 20% of liver cancer-associated fatalities. Dysbiosis of the gut microbiome is associated with the development of ALD, with the gut microbial metabolite urolithin A (UA) exhibiting a potential f …

Pylum Biosciences has built a technology platform to create antibacterials that target individual strains of bacteria without affecting the microbiota. Its lead preclinical programs target Clostridioides difficile for infectious disease and Fusobacterium nucleatum for colorectal cancer.

Clostridioides difficile is a leading cause of antibiotic associated disease in the United States. The primary virulence factors produced by C. difficile are two large glucosylating toxins TcdA and TcdB. To date, several sequence variants of TcdB have been identified that differ in var …

Fecal microbiota transplantation is an evidence-based therapeutic option for recurrent Clostridium difficile infection, involving the transfer of healthy donor fecal material to restore gut micr...

2-piperidone is a crucial industrial raw material of high-value nylon-5 and nylon-6,5. Currently, a major bottleneck in the biosynthesis of 2-piperidone is the identification of highly efficient 2-piperidone synthases. In this study, we aimed to identify specific strains among 51 human gut bacterial …

Bruce Jones, PharmD, FIDSA, BCPS offered clinical considerations for patient dosing and clinical management strategies associated with concurrent therapy.

Tear matrix metalloproteinase (MMP)-9 is an inflammatory signal in patients with dry eye (DE). In the present study, to understand the action mechanism of probiotic LB101 (Lactobacillus plantarum NK151 and Bifidobacterium bifidum NK175 [4:1] mix) against DE, we investigated its effect on tear amount …

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by inflammation and joint damage. Existing treatment options primarily focus on managing symptoms and slowing disease progression, often with side effects and limitations. The gut microbiome, a vast community of microorganisms p …

CRPC remains a significant challenge in prostate cancer research. We aimed to elucidate the role of gut microbiota and its specific mechanisms in CRPC using a multidisciplinary approach. We analyzed 16S rRNA sequencing data from mouse fecal samples, revealing substantial differences in gut microbiot …

Despite brain physiological functions or pathological dysfunctions relying on the activity of neuronal/non-neuronal populations, over the last decades a plet...

Antibiotic-induced gut microbiota disruption constitutes a major risk factor for Clostridioides difficile infection (CDI). Further, antibiotic therapy, which...

Clostridiodes difficile infection (CDI) continues to be one of the leading causes of healthcare-acquired diarrhea and infections, and recurrence is the biggest challenge in its management. As technology and research have led to a better understanding of the pathophysiology of C. difficile, we have come to appreciate the role that the gastrointestinal microbiota plays in infection onset and the prevention of recurrence. The gut microbiota is disrupted in those with CDI, which allows further propagation of the infection leading to recurrence, if the microbiota deficiency is unable to regrow itself. While antimicrobial therapy is necessary for treatment of any CDI, these therapeutics do not address the underlying disturbance of microbiota. Microbial remodulation therapies have been developed supplementing the microbiota deficiency that exists after the standard of care antimicrobial resulting in a reduction of recurrence. Fecal microbiota transplantation (FMT) was the initial attempt for this type of therapeutic and proved to be safe and effective, however never achieved FDA approval. In light of this, live biotherapeutic products (LBPs) were developed by pharmaceutical companies through a more standardized and regulated process. These products are safe and efficacious in reducing CDI recurrence when given after a standard of care antimicrobial, eventually leading to FDA approval of two products that can now be used widely in clinical practice.
