Results of post-hoc experiments to estimate oxidative stress. a Detection of reactive oxygen species (ROS) following B. bassiana challenge. Bars represent measured reactive oxygen species in B. bassiana (dark bar) and no treatment control (light bar) termite worker guts. b Detection of glutathione S-transferase (GST) activity following B. bassiana challenge. Bars represent measured GST specific activity in B. bassiana treatments (dark bar) and negative controls (light bar) for termite worker guts normalized to blanks that received no reduced glutathione. Error bars represent SEM
