This comprehensive review examines the impact of dietary patterns on gut microbiome composition and diversity from infancy to old age, linking these changes age-related health outcomes. It investigates how develops across life stages, focusing influence factors. The explores early-life feeding practices, including breastfeeding formula feeding, shape infant microbiota have lasting effects. In elderly individuals, alterations in are associated with increased susceptibility infections, chronic inflammation, metabolic disorders cognitive decline. critical role diet modulating throughout is emphasised, particularly potential benefits probiotics fortified foods promoting healthy ageing.

From islands to infectomes: host-specific viral diversity among birds across remote islands

BMC Ecology and Evolution, Год журнала: 2024, Номер 24(1)

Abstract Background Accelerating biodiversity loss necessitates monitoring the potential pathogens of vulnerable species. With a third New Zealand's avifauna considered at risk extinction, greater understanding factors that influence microbial transmission in this island ecosystem is needed. We used metatranscriptomics to determine viruses, as well other organisms (i.e. infectomes), seven bird species, including once critically endangered black robin ( Petroica traversi ), on two islands remote Chatham Islands archipelago, Zealand. Results identified 19 likely novel avian viruses across nine viral families.

Archaeal diversity in the microbiomes of four wild bird species

Microbiology Spectrum, Год журнала: 2025, Номер unknown

ABSTRACT Archaea are generally low-abundance members of the vertebrate microbiota that require specific PCR primers to be detected in metabarcoding studies, and robust intraspecific sample size is necessary for well-supported conclusions about archaeal diversity. Using 16S rRNA gene amplicons generated using both Archaea-Specific Universal primers, we investigated prokaryotic diversity 110 fecal samples from four wild bird species different orders: Anna’s Hummingbird ( Calypte anna ), Saltmarsh Sparrow Ammospiza caudacuta Ruddy Turnstone Arenaria interpres Canada Goose Branta canadensis ). Our aim was test hypotheses would offer higher resolution ecologically distinct host have communities. resulted increases richness detection all birds compared primers. The ammonia-oxidizing order Nitrososphaerales species, methanogenic orders were enriched Geese. In Bacteria-Archaea co-occurrence networks, found many more significant interactions than alone. Methanogenic dominated Geese a lesser extent other suggesting an important functional role methanogens Overall, this study advances our knowledge component microbiome provides insight into potential roles play studies avian gastrointestinal microbiota.

This demonstrates improved capability detect widely used We also identified shared species-specific taxa with implications importance.

Location Matters: Variations in Cloacal Microbiota Composition of Spatially Separated Freshwater Turtles

Microbial Ecology, Год журнала: 2024, Номер 87(1)

The gut microbiota of vertebrates is malleable and may be shaped by both intrinsic extrinsic factors. Here, the effect that geography has on cloacal two species Australian freshwater chelonians, eastern longneck turtle (Chelodina longicollis) Macquarie River (Emydura macquarii), captured from waterbodies with different levels anthropogenic pressure was investigated. We analysed composition, structure diversity through 16S rRNA gene amplicon sequencing. It hypothesised animals less disturbed environments would harbour a more diverse microbial population. microbiotas 93 turtles (C. longicollis n = 78; E. macquarii 15), five locations, were analysed. For species, most predominant phylum Proteobacteria. Cloacal alpha varied significantly between C. all but no differences found for macquarii. In longicollis, wetlands within centre Melbourne had lowest metrics, while highest values seen in an undisturbed rural waterbody. Beta diversity, obtained weighted UniFrac distance, showed significant locations capture this investigation. 87 biomarkers identified responsible explaining macquarii, 42 found. This first study to explore composition gives greater insight into community structures turtles. Our demonstrated influenced locality disrupted reduce longicollis. Interestingly, we discovered effects location contrasted not However, beta notably habitat type. These results highlight need interpret chelonian data context human disturbance environment.

Microclimate shapes the phylosymbiosis of rodent gut microbiota in Jordan’s Great Rift Valley

Host phylogeny and the environment play vital roles in shaping animal microbiomes. However, effects of these variables on diversity richness gut microbiome different bioclimatic zones remain underexplored. In this study, we investigated host zone composition microbiota two heterospecific rodent species, spiny mouse Acomys cahirinus house Mus musculus , three African Great Rift Valley (GRV). We confirmed using D-loop sequencing method analyzed influence parameters high-throughput amplicon 16S rRNA gene fragments. Phylogenetic analysis supported morphological identification rodents revealed a marked genetic difference between species. found that had significant effect while did not. Microbial alpha hosts was highest Mediterranean forest zone, followed by Irano–Turanian shrubland, lowest Sudanian savanna tropical zone. The beta species showed differences across Mediterranean, Irano–Turanian, regions. phyla Firmicutes Bacteroidetes were highly abundant, Deferribacterota, Cyanobacteria Proteobacteria also prominent. Amplicon sequence variants (ASVs) identified unique to core families recovered study consistent among hosts. decreased conspecific populations at lower altitudes is linked adaptation its environment, underscores importance incorporating climatic factors such as elevation ambient temperature, empirical research first describe from GRV.

Gut microbiome studies have gained significant attention in recent years due to their potential unveiling the role of microbial communities animals’ health and ecological processes. However, lack standardized protocols sample handling processing across introduces variability, impeding comparability findings. This study addresses this issue by examining methodological variations gut research on wildlife domesticated animals Southeast Asia. A comprehensive search 91 relevant SCOPUS database yielded 54 suitable publications for review, encompassing diverse taxa such as invertebrates (20), fishes (7), reptiles (3), birds (5), mammals (19). Notably, various approaches were employed characterize communities, including source isolation, culture-based approaches, sequencing methods, targeted markers. Based information provided study, future should strive develop guidelines best practices specific studies. would enhance facilitate integration Such efforts will also advance our understanding diversity associated with wildlife, its implications conservation.
