CS and infection: In addition to the unchanged complex III protein levels and activity, we did not detect any loss in citrate synthase activity with infection (p = 0.6; control mice; 1.146 ± 0.10 U/mg protein, infected mice day 10; 1.046 ± 0.12 U/mg protein, infected mice day 14; 1.02 ± 0.026 U/mg protein).
