Crystal violet staining reveals distinctive RAW264.7 cell morphology in response to S. anginosus. Representative photograph of crystal violet staining of RAW264.7 macrophages (20×) depicts the macrophage phenotype that was analyzed after 6 h (top) and 24 h (bottom) post-infection at MOI 10. S. anginosus-infected macrophages showed a distinct phenotype with extended pseudopodia structures compared with untreated, LPS-treated, and S. mitis-infected macrophages (n = 3).
