Probiotic Delivered to the Small Intestine Changes Microbiota

This study will determine whether encapsulation of probiotic bacteria using natural plant protein can enhance bacterial colonisation. Lactobacillus rhamnosus is an ideal strain for the intervention, as it has been shown to affect overall gut health, gut-brain axis, and brain function. Participants aged 25 to 65 years will be recruited and assessed on four occasions to compare the effects of the blood chemicals and bacterial composition in faeces of a 28-day ingestion of a yoghurt beverage with and without the probiotic strain of interest. The study window will be 70+/13 days. This study will provide important information regarding the physiological function of probiotics in the small intestine. Understanding the underlying physiological effects of targeted probiotic delivery to the intestine and the impact on the microbiome is important for health outcomes.

Encapsulated Probiotics & Gut Microbiota

The aim of this study is to determine whether encapsulation of probiotic bacteria using natural plant protein can enhance bacterial colonisation. Lactobacillus rhamnosus is an ideal strain for the intervention, as it has been shown to affect overall gut health, gut-brain axis, and brain function. Fifty participants aged 25 to 65 years will be recruited and assessed on four occasions to compare the blood and faecal effects of a 28-day ingestion of a yoghurt beverage with and without the probiotic strain of interest. The study window will be 70+/13 days. The current study will provide important information on the physiological function of probiotics in the small bowel. Understanding the underlying physiological effects of targeted probiotic delivery to the intestine and the impact on the microbiome is important for health outcomes.

Safety and Efficacy of Lyophilized Fecal Microbiota Transplantation Via Capsules for Intestinal Multidrug-resistant Bacteria Decolonization

The goal of this clinical trial is to learn if oral capsules containing lyophilized stool from healthy donors (fecal microbiota transplantation or FMT) can safely and effectively decolonize multidrug-resistant organisms (MDROs) from the intestines in adults. The main questions it aims to answer are: 1. Does FMT via oral capsules reduce or eliminate intestinal MDRO colonization? 2. What side effects or adverse events occur after taking FMT capsules? Researchers will compare FMT capsules to placebo capsules to see if FMT is effective and safe for decolonizing MDROs. Participants will: * Take either FMT capsules or placebo capsules by mouth * Attend 4 follow-up study visits over 6 months (180 days) for microbiological testing and safety monitoring * Provide stool samples and report any side effects

Nasal Antisepsis for C. Auris Prevention

This is a randomized, controlled, open-label trial of effect of 10% povidone iodine intranasal antisepsis on the detection of Candida auris.

Decolonization Efficacy of Polyhexanide vs. Mupirocin

This pilot randomized controlled trial evaluates the feasibility, tolerability, and preliminary efficacy of a decolonization regimen using polyhexanide in reducing Staphylococcus aureus colonization in the preoperative phase of elective spine surgery, compared to the standard mupirocin and chlorhexidine regimen. The trial involves 24 participants randomized into two groups: one receiving polyhexanide and the other receiving mupirocin and chlorhexidine. The primary outcome is the randomization rate, with secondary outcomes including other feasibility outcomes, tolerability, and efficacy measures such as the reduction in S. aureus colony-forming units (CFUs) and changes in the nasal and skin microbiome composition.
