Bacterial concentrations (CFU/ml) in spleen (a) and cerebellum (b) as well as meningeal inflammation score (c) of young (n = 15) and aged (n = 14) mice at the time of death caused by intracerebral infection with S. pneumoniae serotype 3. Symbols represent values of individual mice, and bars indicate medians, 25th and 75th percentiles. Meningeal inflammation score was calculated counting neutrophilic granulocytes in one high-power field (× 40 objective) on stained sections of three superficial meningeal regions and the hippocampal fissure and classified as follows: no leukocytes [score 0], < 10 leukocytes [score 1], 10–50 leukocytes [score 2], > 50 leukocytes [score 3]
