Microplastics and gut microbiomes impact on Yunnan snub-nosed monkeys in the Three Parallel Rivers region in China

Researchers studied microplastic exposure in endangered Yunnan snub-nosed monkeys in China, finding that exposure levels were linked to provisioned food, social dominance hierarchy, and age. Evidence indicates that current microplastic intake levels did not cause significant gut microbiome disruption in these primates, providing a baseline for conservation planning.

Macrogenomes reveal microbial-mediated microplastic degradation pathways in the porcine gut: a hope for solving the environmental challenges of microplastics

A metagenomic study of pig gut contents found a diverse community of microorganisms harboring genes capable of breaking down multiple types of microplastics. This raises the intriguing possibility that gut microbiota in food animals may partially degrade ingested microplastics, but it also raises questions about whether breakdown products or altered microbial communities pose risks that pass up the food chain to humans.

Gut microbiota reflect adaptation of cave-dwelling tadpoles to resource scarcity

Researchers studied the gut microbiota of cave-dwelling frog tadpoles that spend three to five years developing underground in resource-scarce conditions. They found that the cave dwellers harbored unique bacterial communities enriched in enzymes for breaking down plant fibers and producing short-chain fatty acids, potentially aiding nutrition under food scarcity. The study suggests that gut microbiota play a key role in helping organisms adapt to extreme, nutrient-limited environments.

Microplastic-associated gut microbial profile and antibiotic resistance in preschool children: a multicentre cross-sectional study in China

In a multicentre study of 335 preschool children across three Chinese cities, researchers detected eight types of microplastics in fecal samples at a median concentration of 212.1 micrograms per gram. The study found that microplastic exposure was associated with changes in gut microbiota composition and function, including metabolic pathways related to macronutrients and vitamins, as well as a relationship with antibiotic resistance gene abundance.

Comparative analysis of gut fungal composition and structure of the yaks under different feeding models

Researchers compared the gut fungal communities of wild yaks, house-fed domestic yaks, and grazing domestic yaks on the Tibetan plateau. They found that wild and grazing yaks had significantly more diverse gut fungal communities than house-fed yaks, with the feeding model strongly influencing which fungal species thrived. The study suggests that natural grazing supports a richer gut microbiome in yaks compared to indoor feeding, with potential implications for animal health and digestion.

Study on the association between microplastic exposure and gut microbiota based on metagenomics: A pilot study on 66 young college students in China

In a pilot study of 66 young college students in China, researchers analyzed stool samples to examine the relationship between microplastic exposure and gut microbiota composition. Participants with higher microplastic concentrations in their stools showed increased abundance of potentially harmful intestinal bacteria, with polystyrene microplastics having the most pronounced effect on gut microbial community structure.

Variations and Interseasonal Changes in the Gut Microbial Communities of Seven Wild Fish Species in a Natural Lake with Limited Water Exchange during the Closed Fishing Season

Researchers analyzed the gut bacteria of seven wild fish species in Chaohu Lake, China, across all four seasons and found significant differences in microbial communities between species and across seasons. Environmental factors like water temperature and dissolved oxygen levels were key drivers of these microbial shifts. The study provides a baseline understanding of how natural conditions shape the gut health of wild freshwater fish populations.

Population response of intestinal microbiota to acute Vibrio alginolyticus infection in half-smooth tongue sole (Cynoglossus semilaevis)

Researchers examined intestinal microbiota responses to acute Vibrio alginolyticus infection in half-smooth tongue sole, finding that infection increased vulnerability to secondary infections by intestinal pathogens and promoted antibiotic resistance gene transfer.

First Report of Microplastics in Wild Long-Tailed Macaque (Macaca fascicularis) Feces at Kosumpee Forest Park, Maha Sarakham, Thailand

Researchers report the first detection of microplastics in the feces of wild long-tailed macaques at a forest park in Thailand. They found various types and sizes of microplastic particles in the samples, indicating that these primates are ingesting plastics from their environment. The study raises concerns about the extent of microplastic contamination reaching wildlife in natural habitats through dietary exposure.

Integrated Analysis of the Transcriptome and Microbial Diversity in the Intestine of Miniature Pig Obesity Model

Researchers fed miniature pigs a high-fat, high-carbohydrate diet for 26 weeks and compared their gut health to pigs on a normal diet. The obesity-prone pigs showed increased inflammation, disrupted blood sugar metabolism, and significant declines in beneficial gut bacteria. The study reveals strong connections between diet-induced gut microbial changes and immune-related gene expression in the intestines.

Microplastic pollution of threatened terrestrial wildlife in nature reserves of Qinling Mts., China

Researchers found microplastics in the feces of three threatened wildlife species in China's Qinling Mountains nature reserves, including the golden snub-nosed monkey and leopard cat. Thirty-four types of microplastics were identified, with predators like the leopard cat having the highest levels, likely due to accumulation through the food chain. The finding that even protected wildlife in remote nature reserves is contaminated with microplastics shows how widespread this pollution has become.

Influence of selected dosages of plastic microparticles on the porcine fecal microbiome

Researchers fed pigs different doses of PET microplastics for 28 days and analyzed changes in their gut bacteria. Higher doses of microplastics increased certain bacterial groups that produce short-chain fatty acids, which are important for gut health and immune function. Since pig digestive systems are similar to humans, these results suggest microplastic exposure could alter our gut microbiome in ways that affect digestion and overall health.

Polystyrene microplastic exposure induces selective accumulation of antibiotic resistance genes in gut microbiota and its potential health risks

Researchers used advanced genomic techniques to examine how polystyrene microplastic exposure affects antibiotic resistance genes in the gut bacteria of rats. They found that microplastic exposure selectively increased certain types of antibiotic resistance genes and promoted their ability to transfer between bacterial species. The study suggests that microplastic ingestion could contribute to the spread of antibiotic resistance within the gut, posing potential health risks.
