Oxygenation concentration from rats at 3, 6, 24, 48, 72, and 168 h post-challenge with different titers of A. baumannii strain 307-0294. Rats were given 7.0 × 106, 5.8 × 107, 3.5 × 108, 4.3 × 108, and 7.7 × 109 CFU of 307-0294 by intratracheal instillation, and aortic blood was obtained at 3, 6, 24, 48, 72, and 168 h for determination of PaO2/FiO2 (mm Hg). There was a trend for increased oxygenation at 24 h in rats challenged with 7.0 × 106 CFU compared to rats challenged with 3.5 × 108 and 7.7 × 109 CFU (&, P = 0.02 and 0.04, respectively). Data are means ± standard errors of the means for n = 3 for each challenge titer and time point.
