Figure 4. Hemorrhagic shock prior to methicillin-susceptible S. aureus (MSSA) pneumonia induces a bacteriemia.

Figure 4

Four groups of mice were studied: sham-treated (S group), Hemorrhaged mice (H group), MSSA-induced pneumonia (P group), and hemorrhage before MSSA-induced pneumonia (HP group). Mice were sacrificed 12, 24, or 48 hours after pneumonia onset. MSSA counts in (A) lungs and (B, C) spleen homogenates were performed after culture on specific media. Detection threshold was 0.7 colony forming unit (CFU) per gram of tissue. MSSA counts were always below the threshold in the S and H groups. Data are representative of three independent experiments (each group, n = 6). Data are presented as mean ± SEM (A, B) or percentage ± SEM (C). & P<0.05 versus P and HP groups; *P<0.05 versus group P.
