In this study, we conducted a systematic analysis of 2053 gut metagenomes from 14 globally-sampled public cohorts and a newly recruited cohort. Despite substantial regional and cohort-level heterogeneity in microbiome composition, we elucidated that the consistent differences between groups in microbial signatures provide the fundamental basis for CRC detection. These patterns enabled robust performance in both inter-cohort and independent validations using an optimized bioinformatics framework. In contrast, such basis was lacking in ADA-associated microbial markers, limiting the generalizability of early detection models. To address this, we developed an instance-based transfer learning approach, Meta-iTL, which effectively leveraged knowledge from existing datasets to detect CRC risk at the ADA stage in the newly recruited cohort.

In this study, we constructed a high-resolution map of the jejunal mucosal microenvironment in BCoV-infected calves. Our findings revealed that BCoV infection led to severe microbial dysbiosis, characterized by a marked reduction in Phocaeicola coprophilus (formerly known as Bacteroides coprophilus) and decreased secondary bile acid, especially deoxycholic acid (DCA).

At the host level, BCoV infection altered the composition of jejunal mucosal cells and affected metabolic and immune-related pathways. The differentiation of CD4⁺ T cells played a central role in the jejunum's response to BCoV infection. By integrating these metabolic alterations with dynamic host cellular responses, we suggested a putative that DCA deficiency might contribute to the pathological polarization of CD4<sup>+</sup> T cells toward a Th17 phenotype while suppressing Treg differentiation.
