3.4 Diffirential microbiota among sampling sites
polyp
Histograms of LDA scores (> 4.0) for the differential bacterial taxa in normal colorectal mucosa, polyp tissue and faecal samples were screened out using the LEfSe analysis. Compared with the faecal sample, in the polyp tissues, Differential abundant genera were screened out using LEfSe analysis We further compared genera in different sampling sites using Mann-Whitney statistic analysis. Consistent with the results of the LEfSe analysis, Key genera in five groups. Although there is no significance in the overall structure, some abundant genera were screened out using LEfSe analysis. As shown in
