Relative abundance of bacterial genera in mice treated with PM2.5 and pneumococcus. The bacteria taxonomic profiles at the genus level in BALF microbiome from PM2.5-treated (PM) and/or pneumococcus-infected (Sp) mice. (A) The top 15 most abundant genera among four groups were shown. Relative abundances of (B) Rothia, (C) Streptococcus, (D) Pelagibacterium, (E) Lachnoanaerobaculum, (F) Peptoniphilus, (G) Leptotrichia, and (H) Actinomyces in BALF microbiota community were analyzed. Student’s t-test was used to analyze the statistical significance of the experimental results between two groups. *P < 0.05; **P < 0.01; ***P < 0.001.
