Isolation and Pathogenicity of a Chinese Porcine Astrovirus Type 5 Strain HNPDS-01 and Its Influence on Cecum Microbiota in Piglets

Figure 7

Alteration of the microbiota diversity and composition in the cecum of piglets. (a) Venn diagram of shared OTUs based on the sequences with in each group of piglets (n = 3). (b) The alpha diversity indexes of the cecum microbiota in piglets (n = 3). (c) Diversity of cecum microorganisms between control and PAstV 5 infection groups by PCoA. (d–i) Diversity of cecum microorganisms between control and PAstV 5 infection groups at the phylum, family, and genus levels. The distribution of cecum microorganism at phylum, family, and genus levels, and the distributional trends of cecum species composition differences and species abundance were analyzed by QIIME2. The statistical analysis was performed with a multiple t test. Compared with the corresponding control, the difference was significantly relative when and .
