Sepsis has been characterized as a dysregulated host response to infection, and the role of the microbiome as a key influencer of this response is emerging. Disruption of the microbiome while treating sepsis with antibiotics can itself result in immune dysregulation. Alterations in the gut microbiome resulting from sepsis and its treatment have been implicated in organ dysfunction typical of sepsis across multiple tissues including the lung, kidney, and brain. Multiple microbiota-directed interventions are currently under investigation in the setting of sepsis, including fecal transplant, the administration of dietary fiber, and the use of antibiotic scavengers that attenuate the effects of antibiotics on the gut microbiota while allowing them to concentrate at the primary sites of infection. The emerging evidence shows that the gut microbiome interacts with various elements of the septic response, and provides yet another reason to consider the judicious use of antibiotics via antibiotic stewardship programs.

Hibernation is a necessary means for animals to maintain survival while coping with low temperatures and food shortages. While most studies have largely focused on mammalian hibernation, its reptilian equivalent has been less studied. In order to provide insights into the energy metabolism and potential microbial regulatory mechanisms in hibernating snakes, the serum, liver, gut content samples were measured by multi-omic methods.

The therapeutic benefits of opioids are compromised by the development of analgesic tolerance, which necessitates higher dosing for pain management thereby increasing the liability for drug dependence and addiction. Rodent models indicate opposing roles of the gut microbiota in tolerance: morphine-induced gut dysbiosis exacerbates tolerance, whereas probiotics ameliorate tolerance. Not all individuals develop tolerance, which could be influenced by differences in microbiota, and yet no study design has capitalized upon this natural variation.

Background: Preventing hepatic encephalopathy (HE) recurrence in cirrhosis, which is associated with an altered gut-liver-brain axis, is an unmet need. Fecal microbiota transplantation (FMT) is beneficial in phase-1 studies, but route and dose-related questions remain.
Methods: We performed a phase-2 randomized, placebo-controlled, double-blind, clinical trial of capsule and enema FMT in cirrhosis and HE on lactulose and rifaximin.

Understanding the dynamics of fecal bacterial communities is crucial for managing public health risks and protecting drinking water resources. While extensive research exists on how abiotic factors influence the survival of fecal microbial communities in water, less attention has been paid to the impact of predation by higher organisms, such as the widely distributed grazer Daphnia. Nevertheless, Daphnia plays a significant role in regulating bacterial communities in natural aquatic ecosystems, and recent studies highlighted its potential as a biofilter in alternative tertiary wastewater treatment systems.

Objective: Studies in mouse models and human adults have shown that the intestinal microbiota composition can affect peripheral immune cells. We here examined whether the gut microbiota compositions affect B and T-cell subsets in children.
Methods: The intestinal microbiota was characterized from stool samples of 344 10-year-old children from the Generation R Study by performing 16S rRNA sequencing.
