Core Insights - A recent study presented at UEG Week 2025 indicates that microplastics alter the human gut microbiome, with changes resembling patterns associated with depression and colorectal cancer [1][2] - This research is among the first to directly examine how different types of microplastics interact with the human gut microbiome [1] Summary by Sections Study Methodology - The study utilized fecal samples from five healthy volunteers for in vitro gut microbiome cultivation, exposing these cultures to five common types of microplastics: polystyrene, polypropylene, low-density polyethylene, polymethyl methacrylate, and polyethylene terephthalate [1] - Concentrations of microplastics reflected estimated human exposure levels, with higher doses used to investigate potential dose-dependent effects [1] Findings on Bacterial Composition - While total bacterial cell counts and viable bacterial cell counts remained largely unchanged, the acidity of the microplastic-treated cultures significantly increased compared to the control group, indicating altered microbial metabolic activity [1] - Specific changes in bacterial composition were observed, with certain bacterial populations increasing or decreasing depending on the type of microplastic, particularly within the phylum Firmicutes, which is crucial for digestion and overall gut health [1] Chemical Changes and Disease Implications - Changes in the chemical substances produced by bacteria accompanied the shifts in bacterial composition, with some correlating with the observed increase in acidity [2] - Certain types of microplastics altered levels of pentanoic acid and 5-aminopentanoic acid, while others affected lysine or lactic acid, highlighting the complexity of microplastic-microbiome interactions [2] - Notably, some of the microbially induced changes reflect patterns previously associated with diseases such as depression and colorectal cancer, underscoring the potential health risks linked to microplastic exposure [2]
