WebReactive oxygen species cause oxidative damage to several bacterial targets, including DNA (Imlay et al., 1988). As purine auxotrophs lack the ability to synthesize purine nucleotides and hence DNA and RNA, we hypothesized that the intramacrophage attenuation of purine auxotrophs might be due to their inability to repair DNA damage caused by ROS. darren bass coxhealth
