a Intracellular ROS levels in splenocytes of BALB/c mice at 3 days or 6 weeks after treatment termination. ^# and ^* indicate significant differences, compared to infected and healthy (negative) control groups, respectively. ^Z indicates statistically significant differences between the Ole-treated groups indicated with brackets. b-e Representative flow cytometry histograms derived from experimental groups at 3 days after treatment termination. Blue and pink curves represent ROS levels in healthy control and infected control groups, respectively. Red curves represent ROS levels induced by H₂O₂ in uninfected splenocytes. Green curves represent ROS levels in infected splenocytes that received the indicated treatments
