“…Recent investigations on SCFAs also demonstrated their positive impacts in cell proliferation, gut microbial homeostasis, and intestinal barrier function [58][59][60]. Consistent with the current study, MP exposure has also been previously reported to result in a decrease in SCFA-producing bacteria [43]. Importantly, we also found that MP exposure could increase the levels of some pathogenic bacteria, such as Facklamia and Escherichia_Shigella.…”

“…Similarly, Sun et al showed that MP exposure resulted in decreased colonic mucin production, inflammatory responses, and gut microbiota dysbiosis [1]. The indices representing the diversity and abundance include Chao1, ACE, Shannon, and Simpson, which can be used to assess gut microbial homeostasis [43]. Consistent with previous studies, we observed that MP exposure could decrease the Chao1 and ACE indices of gut microbiota in chickens, indicating that MP exposure can decrease gut microbial abundance and induce gut microbial dysbiosis [44].…”

As novel environmental contaminants, MPs exist widely in the environment and accumulate in organisms, which has become a global ecological problem. MP perturbations of organismal physiology and behavior have been extensively recorded in aquatic animals, but the potential effects of MPs on poultry are not well characterized. Here, we explored the adverse effects of MP exposure on the growth performance and gut microbiota of chickens. Results showed that the growth performance of chickens decreased significantly during MP exposure. Additionally, Firmicutes, Bacteroidota, and Proteobacteria were found to be dominant in the gut microbiota of MP-exposed chickens, regardless of health status. Although the types of dominant bacteria did not change, the abundances of some bacteria and the structure of the gut microbiota changed significantly. Compared with the controls, the alpha diversity of gut microbiota in chickens exposed to MPs showed a significant decrease. The results of comparative analyses of bacteria between groups showed that the levels of 1 phyla (Proteobacteria) and 18 genera dramatically decreased, whereas the levels of 1 phyla (Cyanobacteria) and 12 genera dramatically increased, during MP exposure. In summary, this study provides evidence that exposure to MPs has a significant impact on the growth performance and gut microbial composition and structure of chickens, leading to a gut microbial imbalance. This may raise widespread public concern about the health threat caused by MP contamination, which is relevant to the maintenance of environmental quality and protection of poultry health.
