FIG. 2.

Mice infected with BC7/alginate show severe inflammation. Paraffin lung sections were prepared for mice infected with BC7/PBS (A and B) or BC7/alginate (C to F) at day 1 (A and C), day 5 (B and D), and day 7 (E and F) postinfection and stained with H&E. The insets in panels A, C, and D are magnifications of the areas in boxes to show neutrophil accumulation. Arrows in panels E and F point to areas of inflammation. The images are representative of the results for three individual animals at each time point.
