Impact of As on S. aureus adhesion (A) and infection (B) of MAC-T cells. The MAC-T cell viability after exposure to different concentrations of As by MTT assay is presented in panels (C) and the S. aureus growth curves are presented in panel D. Cell viability is expressed as a percentage of control cells (assigned as 100%). All experiments were performed in triplicate and the results are represented as means ± standard deviation (SD). Student’s t test was performed to assess significance with the P values being indicated on graphs
