Lung histological examination after infection.

<p>Pathological mapping of the lungs of non-treated (NT) (<b>A</b>), deferred-treatment (DT) (<b>B</b>) and immediate-treatment (IT) (<b>C</b>) groups. Photomicrographs of the pathological Giemsa staining of the lung sections (100X). Mean histological severity score (HSS) was 2.64±0.4 (mean ± SD) for the NT group, 1.27±0.6 for the IT group (p = 0.005 <i>vs.</i> NT) and 2.32±0.4 for the DT group (p = NS <i>vs.</i> NT).
