FIG 1.

Methicillin-resistant Staphylococcus aureus (MRSA) concentrations in lung tissue. Data points indicate MRSA colonization of lung tissue samples in the dependent (ventral) (a) and nondependent (dorsal) (b) pulmonary regions. Solid horizontal lines depict the medians, while error bars show the 95% confidence intervals. MRSA colonization in lung tissue did not differ among the groups in the dependent pulmonary regions (P = 0.260), but it differed significantly in the nondependent sections (P = 0.049).
