MPO and oxidant–antioxidant enzyme activities. Lung tissues were collected and homogenized to determine MPO activity (A) and SOD (B) and MDA (C) levels at 96 h after Mycoplasma pneumoniae infection. MPO, myeloperoxidase; SOD, superoxide dismutase; MDA, malondialdehyde. NS + NS, uninfected immunocompetent mice; CYP + NS, uninfected immunocompromised mice; NS + MP, infected immunocompetent mice; CYP + MP, infected immunocompromised mice. Values are presented as mean ± standard deviation (n = 6). *P < 0.05; **P < 0.01; ***P < 0.001.
