Figure 4. Exposure to O3 was Positively Associated with the Relative Abundance of Taxa Belonging to the Bacteroides Genus and was Negatively Associated with Gut Bacterial Diversity using Whole Genome Sequencing (WGS) Taxonomically Classified by Kraken2.

Figure 4

Higher exposure to O3 was positively associated with the relative abundance of the genus Bacteroides (A) and the relative abundance of the bacterial species Bacteroides caecimuris (B). Higher exposure to O3 was associated with a lower bacterial Shannon diversity index (C) and evenness (D) at the species level.
