NO accumulated in iron-deficient T. vaginalis.
a Antioxidant capacity of iron-rich (IR) and -deficient (ID) cells representing the reducing power (Cu++ to Cu+) of each lysate. ROS (CM-DCF DA) b and NO (CM-DAF FM) c were examined. IR, iron rich (80 μM FAC); ID, iron deficient (180 μM DIP). The data are presented as the mean ± SD of three independent experiments. *** p < 0.001, compared with the IR group
