The dose dependency and radiographic appearance of <i>S. aureus</i> pneumonia.

<p>(A): Bacterial burden and percent mortality during <i>S. aureus</i> pneumonia following 24 hours post intranasal (i.n.) infection. The horizontal bar in the left most figure represents the average bacterial burden presented as colony forming units of homogenized lung tissue with the boxes representing the standard deviation of the sample population. (B): Murine CT imaging correlated with pulmonary pathology at 24 hours. (C): Murine serial CT imaging of a single mouse following i.n. inoculation with 3.7×10⁸ CFU <i>S. aureus</i>.
