Published: Sept. 13, 2023

Recent advances in metagenomic analyses have made it easier to analyze microbiota. The microbiota, a symbiotic community of microorganisms including bacteria, archaea, fungi, and viruses within specific environment tissues such as the digestive tract skin, has complex relationship with host. studies revealed that microbiota composition balance particularly affect health host onset disease. Influences diet, food preferences, sanitation play crucial roles composition. oral cavity is where directly communicates outside. Stable temperature humidity provide optimal growth environments for many bacteria. However, unique susceptible pH changes, salinity, nutrients, external pathogens. emphasized importance changes bacterial could contribute development systemic diseases. This review focuses on saliva, IgA, fermented foods because they critical maintaining by regulating its balance. More attention should be paid regulatory factors health.

Metagenomic analysis reveal the phytoremediation effects of monocropping and intercropping of halophytes Halogeton glomeratus and Suaeda glauca in saline soil of Northwestern China

BMC Plant Biology, Journal Year: 2025, Volume and Issue: 25(1)

Published: Feb. 18, 2025

Planting halophytes is a widely used method of phytoremediation for saline soils. The succulent Halogeton glomeratus and Suaeda glauca are remediation soil in the arid region Northwestern China. However, whether intercropping H. S. can increase improvement effect yet to be proved. Therefore, this study analyzed three planting modes: monocropping (Hg), (Sg), (Hg||Sg). These were applied field experiments, with biomass physicochemical properties measured each treatment, mechanism was using macrogenomics. After harvesting after one season, Hg treatment had highest dry total dissolved salt content reduced; correspondingly, pH decreased organic matter increased. results showed that Actinobacteria, Acidobacteria Proteobacteria dominant phylum under four treatments. This suggests more capable producing microorganisms favorable remediation. Thus, effective strategy zone

Detection of Coronaviruses and Genomic Characterization of Gammacoronaviruses from Overwintering Black-Headed Gulls (Chroicocephalus ridibundus) in Yunnan Province, China

Microorganisms, Journal Year: 2025, Volume and Issue: 13(4), P. 874 - 874

Published: April 10, 2025

Black-headed gulls have been confirmed as the natural hosts of Deltacoronavirus (δ-CoV) and Gammacoronavirus (γ-CoV). A total 59 CoV-PCR-positive fecal samples were identified among 509 collected from overwintering black-headed in Yunnan Province, China. The prevalence gull deltacoronavirus (BHG-DCoV) was 3.54% (18/509), while that gammacoronavirus (BHG-GCoV) 8.06% (41/509). BHG-GCoV significantly higher than BHG-DCoV (χ2 = 9.518, p < 0.01). Two complete genome sequences BHG-GCoVs obtained, with lengths 27,358 bp 27,355 bp, respectively, gulls. nucleotide similarity between two genomes is 98.75%. Phylogenetic analysis based on whole has strains clustered into species anatis. Although belong to anatis, they are distantly related representative strain Duck_CoV 2714 exhibit a closer genetic relationship GCoVs Xenus cinereus (AvXc-GCoV) Numenius phaeopus (AvNp-GCoV).

Genetic characterization of the first Deltacoronavirus from wild birds around Qinghai Lake

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: June 12, 2024

Deltacoronavirus, widely distributed among pigs and wild birds, pose a significant risk of cross-species transmission, including potential human epidemics. Metagenomic analysis bird samples from Qinghai Lake, China in 2021 reported the presence Deltacoronavirus. A specific gene fragment Deltacoronavirus was detected fecal birds at positive rate 5.94% (6/101). Next-generation sequencing (NGS) identified novel strain, which closely related to isolates United Arab Emirates (2018), (2022), Poland (2023). Subsequently strain named A/black-headed gull/Qinghai/2021(BHG-QH-2021) upon confirmation Cytochrome b black-headed gull sample.

Saline soil is one of the important environmental problems facing world. Planting halophytes a widely used method phytoremediation for saline soils. The succulent Halogeton glomeratus and Suaeda glauca are remediation in arid region Northwestern China. However, whether intercropping H. S. can increase improvement effect yet to be proved, there no comparative reports on monocropping intercropping. Therefore, this study analyzed three planting modes: (Hg), (Sg), (Hg||Sg). These were applied field experiments, with biomass physicochemical properties measured each treatment, mechanism was using macrogenomics. After harvesting after season, Hg treatment had highest dry 9.6 t ha−1.

The gut microbiota of migratory waterbirds is affected by various complex factors, including cross-species transmission, which increases the risk pathogen spreading among sympatric animals and poses a potential public health to humans. In this study, we investigated microbial communities wintering Anser fabalis, Domestic Ducks (Anas platyrhynchos domesticus), humans, soil using high-throughput sequencing 16S rRNA gene region in Shengjin Lake, China. total, 6,046,677 clean reads were obtained, representing 41,119 operational taxonomic units (OTUs) across four groups. dominant phyla Proteobacteria, Firmicutes, Bacteroidota, Actinobacteriota. Sorensen similarity index alpha beta diversity results showed that fabalis more similar those other pairs. Network analysis revealed Faecalibacterium prausnitzii, Pseudomonas fragi, Bradyrhizobium elkanii hubs three major modules. Fourteen common microbiomes identified Ducks, Lake. A total 96 pathogens groups, with 20 specific potentially pathogenic found fabalis. Some these are responsible for significant financial losses poultry industry pose risks human health. Klebsiella pneumoniae, Morganella morganii, Escherichia coli, Ralstonia insidiosa core groups at Lake can cause diseases humans facilitate transmission through media. Therefore, contracting from birds because their frequent contact domestic poultry. However, further studies required explore species pathways soil.
