Background: Metabolic syndrome (MetS) presents substantial health risks, and the supplementation of probiotics and prebiotics is regarded as a promising management approach. This study aims to explore the relationship between dietary intake of live microbes and non-dietary prebiotic/probiotic intake and MetS among US adults.
Methods: Data from the National Health and Nutrition Examination Survey 1999-2016 was used in this study. MetS is defined according to the criteria set by the National Cholesterol Education Program-Adult Treatment Panel III-2005. Dietary intake information and probiotic/prebiotic intake data were collected through self-reported questionnaires. Multiple logistic models were applied to explore the relationships between dietary live microbes, and probiotic or prebiotic intake with MetS.
Results: A significantly lower prevalence of MetS was observed in individuals with a high intake of dietary live microbes compared to those with a low intake (OR: 0.79, 95% CI: 0.69-0.91). This association was particularly strong among participants with higher economic status and advanced educational attainment (interaction P < 0.05). Similarly, individuals with non-dietary probiotics intake displayed a similar trend (OR: 0.70, 95% CI: 0.54-0.92). Conversely, there was no significant association found between non-dietary prebiotic intake and MetS.
Conclusions: Dietary live microbes intake and non-dietary probiotic intake were negatively associated with the prevalence of MetS and its components. The study offers novel evidence supporting the effective management of MetS.

The development of safe and effective mucosal vaccines are hampered by safety concerns associated with adjuvants or live attenuated microbes. We previously demonstrated that targeting antigens to the human-Fc-gamma-receptor-I (hFcγRI) eliminates the need for adjuvants, thereby mitigating safety concerns associated with the mucosal delivery of adjuvant formulated vaccines. Here we evaluated the role of the route of immunization in the mucosal immunity elicited by the hFcγRI-targeted vaccine approach.

Jasmonic acid (JA), ethylene (ET) and salicylic acid (SA) are the three major phytohormones coordinating plant defense responses, and all three are implicated in the defense against the fungal pathogen Fusarium oxysporum. However, their distinct modes of action and possible interactions remain unknown, in part because all spatial information on their activity is lacking. Here, we set out to probe this spatial aspect of plant immunity by using live-microscopy with newly developed fluorescence-based transcriptional reporter lines.

Advancing microbiome-gut-brain axis science requires systematic, rational and translational approaches to bridge the critical knowledge gaps currently preventing full exploitation of the gut microbiome as a tractable therapeutic target for gastrointestinal, mental and brain health. Current research is still marked by many open questions that undermine widespread application to humans. For example, the lack of mechanistic understanding of probiotic effects means it remains unclear why even apparently closely related strains exhibit different effects in vivo.

Lacto-fermented fruits and vegetables (FVs) such as kimchi, sauerkraut, and fermented olives and nonalcoholic juices have a long history as dietary staples. Herein, the production steps and microbial ecology of lacto-fermented FVs are discussed alongside findings from human and laboratory studies investigating the health benefits of these foods. Lacto-fermented FVs are enriched in bioactive compounds, including lactic and acetic acids, phenolic compounds, amino acid derivatives such as indole-3-lactic acid, phenyl-lactic acid, γ-aminobutyric acid, and bacteriocins, and beneficial live microbes.

Using synthetic biology techniques, bacteria have been engineered to serve as microrobots for diagnosing diseases and delivering treatments. These engineered bacteria can be used individually or in combination as microbial consortia. The components within these consortia complement each other, enhancing diagnostic accuracy and providing synergistic effects that improve treatment efficacy.
