Gene Ontology (GO) analysis of identified differentially expressed genes (DEGs) in S. aureus after 1 and 3 h of exposure with tonsillar cells. A1 and B1 represent the GO-enriched scatter plots, identified within top 30, from upregulated and downregulated genes The size of the dot represents the number of DEGs, and the color represents level of fold enrichment of the identified GO terms. A2 and B2 represent the hierarchical clustering tree diagram from GO analysis, showing different clades of GO-enriched terms divided into biological processes, cellular processes, or molecular components
