Inflammatory response in lungs of mice infected with four virulent A. baumannii strains.

Mice were intratracheally infected with A. baumannii RUH875, RUH134, LUH5875 or LUH8326 for 1–4 days. Levels of inflammatory mediators were determined in the lung homogenates of mice directly after instillation (basal values), and 1–4 days after instillation. Results are medians and ranges for 8 mice, except for LUH8326 at 3 days after infection, where n = 4. Values are representative for surviving mice only. NA, not assessable, due to the high mortality associated with these strains.*, significantly (p†, results in ng/g of lung tissue;††, results in pg/g of lung tissue.
