Obesity has become a worldwide pandemic affecting more than 650 million people and is associated with a high burden of morbidity. Alongside traditional risk factors for obesity, the gut microbiome has been identified as a potential factor in weight regulation. Although rodent studies suggest a link between the gut microbiome and body weight, human evidence for causality remains scarce. In this Review, we postulate that existing evidence remains to establish a contribution of the gut microbiome to the development of obesity in humans but that modified probiotic strains and supraphysiological dosages of microbial metabolites may be beneficial in combatting obesity.

The inhibitory effects of Lactiplantibacillus plantarum on inflammatory responses are known, but its action mechanisms in oxidative stress, immunomodulation, and intestinal homeostasis remain of interest. Accordingly, we investigated the protective effects of Lactiplantibacillus plantarum SCS2 (L. plantarum SCS2) against sodium dextran sulfate (DSS)-induced colitis in mice as well as elucidated its impact on inflammation, oxidative stress, and intestinal microbiota.

This research evaluated the gut microbiota of Rohu fish from the Halda River and Kaptai Lake in Bangladesh by 16S rRNA sequencing. Distinct microbial profiles were identified, with Halda samples concentrated in pathogens and Kaptai samples abundant in probiotics.

Unlabelled: Severe acute pancreatitis (SAP) is characterized by systemic inflammation and intestinal barrier dysfunction and is often associated with gut microbiota dysbiosis. Rifaximin, a gut-specific non-absorbable antibiotic, is known to modulate the gut microbiota. Here, we investigated rifaximin's effects and mechanisms in SAP using murine models and a single-center, open-label, randomized controlled trial (Chinese Clinical Trial Registry: ChiCTR2100049794).

Gut dysbiosis and an increased risk of respiratory infection in type 2 diabetes have been well recognised. However, the relationship between the gut and respiratory pathobionts carriage rate in the Type 2 diabetic Malaysian population is understudied. To address the knowledge gap, we profiled the gut and upper respiratory tract microbial composition, as well as the urine metabolome of 31 type 2 diabetic adults and 14 non-diabetes adults.
