Microbiome engineering has emerged as a transformative approach to enhancing food safety and quality by strategically modulating microbial communities. This review critically examines state-of-the-art techniques, including synthetic biology, artificial intelligence (AI), systems that are revolutionizing our ability improve nutritional profiles, extend shelf life, optimize production processes. The further explores complex social, ethical, regulatory considerations, emphasizing the importance of robust public engagement establishment standardized frameworks ensure safe effective implementation. While microbiome holds significant promise for control, research is needed address critical challenges, understanding dynamics in developing harmonized frameworks. By bridging interdisciplinary gaps, this paper underscores necessity collaborative efforts unlock full potential microbiome-driven innovations more resilient sustainable industry.

ABSTRACT The various human microbiomes play critical roles in maintaining health and well‐being, they are continuously shaped by a complex web of internal external factors. Research on environmental is generally discrete within disciplinary areas such as medicine, microbiology, molecular ecology, etc. This paper presents perspective based scoping review the literature, aiming to explore how these interconnected shape well‐being and, turn, planetary health. We working from cellular mechanisms population outcomes, role intrinsic extrinsic factors influencing microbiomes. argue that global trends homogenization diets, environments, medical practices driving shifts microbial diversity, with far‐reaching implications for well Disruptions feedback at individual, community, ecosystem levels often exacerbated biodiversity loss change. underscore need holistic public interventions account microbiome stewardship across scales.

Faecal metagenomes of great tits and blue tits provide insights into host, diet, pathogens and microbial biodiversity

Access Microbiology, Год журнала: 2025, Номер 7(4)

Опубликована: Апрель 1, 2025

Background. The vertebrate gut microbiome plays crucial roles in host health and disease. However, there is limited information on the microbiomes of wild birds, most which restricted to barcode sequences. We therefore explored use shotgun metagenomics faecal two bird species widely used as model organisms ecological studies: great tit ( Parus major ) Eurasian blue Cyanistes caeruleus ). Results. Short-read sequencing five samples generated a metagenomic dataset, revealing substantial variation composition between samples. Reference-based profiling with Kraken2 identified key differences ratios reads assigned host, diet microbes. Some showed high abundance potential pathogens, including siadenoviruses, coccidian parasites antimicrobial-resistant bacterial Serratia fonticola . From metagenome assemblies, we obtained complete mitochondrial genomes from Isospora spp., while metagenome-assembled documented new prokaryotic species. Conclusions. Here, have shown utility uncovering microbial diversity beyond what possible 16S rRNA gene sequencing. These findings provide foundation for future hypothesis testing manipulation improve fitness populations. study also highlights role birds dissemination antimicrobial resistance.

We hypothesize that bacteria isolated from free-ranging animals could potentially be useful for practical applications. To meet this objective a Gram-positive bacterium was the gastrointestinal (GI) tract of Gray Wolf (Canis lupus) using Brucella broth with hemin and vitamin K (BBHK). By small ribosomal RNA (16S) gene sequencing initially identified as novel Carnobacterium maltaromaticum strain.

The growing problem of antibiotic resistance calls for a paradigm shift in medication discovery. Fortunately, the enormous oceans, home to an incredible diversity life, provide viable solution: marine metabolites. These unusual chemicals have potential treating wide range diseases. This present study investigates great using these marine-derived gems disease management techniques. Despite difficulty procuring and isolating organisms, discovering most effective metabolites, traversing lengthy research pipelines, rewards are apparent. To demonstrate power resources, paper examines successful case studies. Each delves deeply into single metabolite, including its source organism, it targets, precise mechanism by which metabolite disrupts process. We'll look at results clinical trials that examined efficacy safety medications, eventually exposing real-world influence on patient outcomes after incorporating them treatment plans.

Probiotic colonization of Xenopus laevis skin causes short-term changes in skin microbiomes and gene expression

Infection and Immunity, Год журнала: 2025, Номер unknown

Опубликована: Апрель 2, 2025

Probiotic therapies have been suggested for amelioration efforts of wildlife disease such as chytridiomycosis caused by Batrachochytrium spp. in amphibians. However, there is a lack information on how probiotic application affects resident microbial communities and immune responses. To better understand these interactions, we hypothesized that would alter community composition host expression Xenopus laevis. Accordingly, applied three amphibian-derived anti-Batrachochytrium bacteria strains (two Pseudomonas one Stenotrophomonas sp.) to X. laevis monoculture also cocktail. We quantified structure using 16S rRNA gene sequencing. genes involved responses quantitative reverse transcriptase polymerase chain reaction (RT-qPCR) skin transcriptomics over 1 3-week periods. All treatments successfully colonized 3 weeks, but with differential amplicon sequence variant (ASV) counts time. Bacterial effects were most pronounced at week post-probiotic exposure decreased thereafter. initial changes bacterial alpha beta diversity, including reduction diversity from pre-exposure ASV relative abundance. colonization strain RSB5.4 reduced regulatory T cell marker (FOXP3, measured RT-qPCR) the greatest detected transcriptomics. Single mixed cultures, therefore, altered amphibian microbiome-immune interactions.

ABSTRACT The gut microbiome is an important component of host health and function influenced by internal external factors such as phylogeny, age, diet, environment. Monitoring the has become increasingly management tool for wild populations threatened species. Tasmanian devil ( Sarcophilus harrisii ) largest extant carnivorous marsupial from island state Tasmania, Australia. Devils are currently endangered due to facial tumor disease. Previous assessments have shown differences between captive microbiomes changes during translocations. However, variability across Tasmania drivers these not well understood. We conducted a range‐wide assessment at 10 locations via 16S rRNA sequencing, tested influence diet (12S vertebrate sequencing), location, sex, cohort. show that five most abundant phyla genera were consistent all locations. Location, cohort, sex impacted bacterial richness, but location did impact diversity. While there in state, was no strong evidence juveniles adults, nor males females. Contrary our hypothesis, explained small amount variation microbial communities. suspect other variables, environmental immune system development, may stronger on variability. Dietary components missed 12S primer, including invertebrates plants, also contribute patterns. Adjustments dietary supplementation recommended when preparing devils translocation different sites.
