KEGG enrichment analysis of DEMs in PBMCs, serum and BALF. A KEGG enrichment analysis of DEMs at different infection stages (0–24 h, 24–120 h); Up-regulation and down-regulation of DEMs were analyzed by KEGG enrichment respectively at 0–24 h (B) and at 24–120 h (C). The X-axis indicates the ratio of the DEGs enriched in this pathway to the total DEGs; the Y-axis indicates the KEGG term; the counts and negLog10_qValue indicates the number and degree of enrichment of genes in a category, respectively. *negLog10_qValue > 1.3 were considered significantly enriched by the DEGs
