Comparative analysis of the fecal microbiota in samples from which DNA was extracted by four different methods. (a) Bray-Curtis PCoA. No significant differences were found between fresh and stored samples (p>0.05, PERMANOVA). The samples extracted by method D are indicated with arrows. (b) Chao1 and Shannon indices of fresh and stored samples. No significant differences were found between fresh and stored samples (p>0.05, Kruskal-Wallis test).
