Bifidobacterium longum subsp. longum XZ01 delays the progression of colon cancer in mice through the interaction between the microbial spatial distribution and tumor immunity

we used the conventional microbial research methods of 16S rRNA gene sequencing technology to explore the similarities and differences of microorganisms in colon tumor tissues, in order to combined with flow data to prove that the different polarization direction of macrophages was caused by the different microorganisms accumulated in the tissues.
