Colonic immune cell responses in multidrug-resistant P. aeruginosa infected mice suffering from chronic colitis. IL-10−/− mice with chronic colitis were perorally infected with a multidrug-resistant P. aeruginosa (Psae) strain on day (d) 0. Six weeks thereafter (on d42 postinfection; black circles) the average numbers of colonic (a) macrophages and monocytes (positive for F4/80), (b) T lymphocytes (positive for CD3), (c) regulatory T cells (positive for FOXP3), and (d) B lymphocytes (positive for B220) were determined from six high power fields (HPF, 400x magnification) per animal in immunohistochemically stained large intestinal paraffin sections. Naive (N) IL-10−/− mice served as negative controls (open circles). Numbers of mice (in parentheses), medians (black bars) and significance levels (p-values) determined by the Mann Whitney U test are indicated. Data shown were pooled from three independent experiments.
