Electroacupuncture at Zusanli Alleviates Sepsis by Regulating the TLR4-MyD88-NF-Kappa B Pathway and Diversity of Intestinal Flora

Figure 4

EA at ST36 altered the diversity of the intestinal flora. (a) Rarefaction curves were used to determine whether the amount of sequencing data was sufficient. (b) The differences in diversity of the intestinal flora among groups as noted by alpha diversity. (c) PCA : the closer the two sample points are, the more similar the species composition of the two samples is. (d) NMDS : the closer the sites are, the more similar the species composition of the two samples is. Stress indicates the quality of NMDS analysis results. Generally, it is considered that a stress value less than 0.1 indicates a good sort. OTU: operational taxonomic unit.
