    (1) Sterile mice were exposed to grassland, forest and desert soil environments for 60 days, and then partially transferred to two other environments to collect stool samples;(2) soil bacteria from different environmental types can successfully colonized in the intestines of mice, and the composition and function of intestinal bacteria in different soil mice are significantly different; (3) Early colonization of the intestinal bacteria in the environmental transfer will significantly affect the development of the intestinal bacteria, the formation of a"priority effect", resulting in the environmental changes, the relevant classification groups and functional characteristics of the place of birth still exist;lead recommendation szxearly life environmental exposure can affect the assembly and development of gut microbiotics. A new study published in Gut Microbes by Zhang Peace Of Inner Mongolia Agricultural University, Shi Huang of the Qingdao Institute of Bioenered Energy and Process of the Chinese Academy of Sciences, and Wei Wei of Central China Agricultural University found that exposure to different soil environments in the early life (60 days) was significantly related to the composition and function of the intestinal bacteripolytic groups in mice, and that after the mice were transferred to other environments, the composition and function of the intestinal bacteri groups gradually became consistent with the new soil environment.Gut Microbes

    Abstract:
    Collected
    Environmental exposure exposure life stages can govern the assembly and development of the gut microbiota, yet it is insufficiently understood. In this study, ex-germ-free mice were cohoused with distinct soil-microbiota (from desert, steppe, and forest) beddings within 60 days after birth and subsequently transferred to new soil beddings from 60 to 90th day. Using metagenomic shotgun sequencing, firstly, we found soil microbes from natural environments (birthplace) greatly influenced the gut community assembly in the housing experiment. About 27% microbial species and 12% functional components that associated with birthplaces at Day 60 were still discriminatory of birthplaces after transferring mice to new environments. Moreover, prior soil-exposure types are associated with the magnitude of temporal microbiome change due to environmental shifts. The appropriate soil-exposure (e.g., steppe) might help mice gut microbiome adapt to changing environments or host development. Our study demonstrated the continuous soil-exposure history earlier is associated with the gut microbiome individuality and development later.First Authors:
