Putative ecological functions of bacterial communities altered by PM2.5 and pneumococcus. The functions of bacterial communities were analyzed based on PICRUSt2 by KEGG annotation at level 2. Comparison of the functional profiles between (A) PM2.5-exposed (PM) and unexposed (control) mice; (B) pneumococcal infection (Sp) and PM2.5 plus pneumococcus (PM + Sp) infection.
