ClearDevelopmental Dynamics of the Gut Virome in Tibetan Pigs at High Altitude: A Metagenomic Perspective across Age Groups
Researchers profiled the gut virome of Tibetan pigs at high altitude using metagenomic sequencing, tracking viral community dynamics across different developmental stages. The study identified novel bacteriophages and found that gut viral diversity changed substantially with age, providing baseline data on virome development in this understudied livestock population.
Viral metagenomics reveals persistent as well as dietary acquired viruses in Antarctic fur seals
Researchers analyzed the viruses present in the blood and feces of Antarctic fur seals and identified multiple novel viruses — including crustacean viruses likely acquired through diet — providing a baseline picture of the viral communities in this remote species that may be increasingly exposed to new pathogens through climate change and human activity.
Viral Metagenomics as a Tool to Track Sources of Fecal Contamination: A One Health Approach
This review evaluates viral metagenomics as a tool for tracking sources of fecal contamination across water, food, soil, and air within a One Health framework. Researchers found that viral metagenomics can complement traditional culture and PCR-based methods by identifying a broader range of viral indicators with narrow host ranges. The study discusses both the promise and current limitations of this approach, including challenges in sample processing and bioinformatics analysis.
Potential risk of microplastics in plateau karst lakes: Insights from metagenomic analysis
Researchers surveyed microplastic pollution in remote alpine lakes on the edge of the Tibetan Plateau, finding concentrations of 20 to 59 particles per liter in water and up to 997 particles per kilogram in sediments. Using metagenomic analysis, they discovered that microplastic surfaces harbored distinct microbial communities carrying antibiotic resistance and virulence genes. The study suggests that even pristine high-altitude ecosystems are affected by microplastic contamination with potential ecological risks.
Comparative Analysis of Gut Microbiota Provides Insights into High-altitude Adaptation in Rana kukunoris on the Qinghai-Xizang Plateau
Researchers used 16S rRNA gene sequencing to characterize and compare the gut microbiota of the high-altitude frog Rana kukunoris on the Qinghai-Xizang Plateau with two low-altitude frog species, Rana amurensis and Rana dybowskii. The comparative analysis aimed to identify microbial community differences that may reflect adaptive strategies to extreme high-altitude conditions including low oxygen and harsh temperatures.
Comparative Analysis of Nasal Microbial Community between Tibetan Sheep with different Ages
Researchers compared nasal microbial communities in adult and young Tibetan sheep using amplicon sequencing, finding that young sheep had greater bacterial diversity at the genus level with 185 genera significantly more abundant, though overall alpha diversity indices were similar between age groups.
Multidrug-resistant Escherichia coli causing diarrhea in yak calves on the Qinghai-Tibet Plateau: phenotypic characterization, whole-genome sequencing, and pathogenicity analysis
Scientists found dangerous, drug-resistant E. coli bacteria in sick yak calves in Tibet that doesn't respond to most common antibiotics. These "superbug" strains could potentially spread to humans through the food chain or environment, making infections much harder to treat. This highlights the growing global threat of antibiotic-resistant bacteria, especially in areas where antibiotics are used heavily in livestock.
Viral diversity and potential environmental risk in microplastic at watershed scale: Evidence from metagenomic analysis of plastisphere
Metagenomic analysis of plastisphere communities on microplastics collected from five freshwater sites revealed diverse viral communities including phages and potential animal pathogens, with plastic-associated viromes differing from those in surrounding water. The study identifies microplastics as previously overlooked carriers of viral diversity and potential environmental health risks in aquatic ecosystems.
Review of Methods for Studying Viruses in the Environment and Organisms
This review systematically summarizes methods for extracting and detecting viruses from environmental samples including soil, water, faeces, and air, as well as biological samples from plants and animals, comparing the applicability, advantages, and limitations of each approach for virus ecology research.
VEBA: a modular end-to-end suite for in silico recovery, clustering, and analysis of prokaryotic, microeukaryotic, and viral genomes from metagenomes
Researchers developed VEBA, a modular bioinformatics software suite that automates end-to-end metagenomic analysis for recovering and characterizing genomes of bacteria, microeukaryotes, and viruses from environmental samples, enabling new biological discoveries from existing datasets.
Assessing the Plastisphere from Floating Plastics in the Northwestern Mediterranean Sea, with Emphasis on Viruses
Researchers used DNA sequencing to characterize the plastisphere, the community of organisms colonizing floating plastics in the Northwestern Mediterranean Sea. The study revealed diverse microbial communities including bacteria, algae, and notably viruses, raising questions about how plastic-associated pathogen transport may affect marine ecosystem dynamics.
Diversity and potential functional characteristics of phage communities colonizing microplastic biofilms
Researchers used metagenomics to characterize phage communities colonizing microplastic biofilms, discovering 240 distinct virus types across polypropylene, polyethylene, and PET plastics that differed from those on stone surfaces, suggesting microplastics host unique viral communities with potential ecological implications.

This review provides a comprehensive overview of eco-genomic tools for detecting enteric viruses in aquatic environments, covering conventional and next-generation sequencing approaches. The authors recommend integrating multiple detection platforms and conducting year-round sampling to accurately assess waterborne virus burdens.
Comparative Analysis of the Gut Microbiota between Two Horse Species
Researchers compared the gut microbiota of native Mongolian horses and imported Dutch Warmblood horses using genetic sequencing. They found notable differences in bacterial community composition between the two breeds, suggesting that host genetics plays a role in shaping gut microbial populations. The study adds to the growing understanding of how the gut microbiome varies across closely related animal species.
Identification and prevalence of fluke infection in yak and Tibetan sheep around Qinghai Lake, China
This Chinese study identified and assessed the prevalence of liver and rumen flukes in yak and sheep grazing around Qinghai Lake. While focused on veterinary parasitology rather than microplastics, the study contributes to understanding the health of livestock in a remote region where plastic contamination of grazing land is an emerging concern.
Effects of agricultural inputs on soil virome-associated antibiotic resistance and virulence: A focus on manure, microplastic and pesticide
Researchers studied how agricultural inputs including manure, microplastics, and pesticides affect virus communities in soil and their potential to carry antibiotic resistance genes. They found that manure application significantly increased both viral diversity and the abundance of resistance and virulence genes carried by viruses. The study reveals that soil viruses may play a previously underappreciated role in spreading antibiotic resistance through agricultural ecosystems.
