Immunofluorescent analysis pneumococcal capsules of DCT patients and control meningitis patients. a–e DCT cases with the presence of various amount of intact pneumococcal capsules (a arrow). In case 1 (a), pneumococcal capsules were present sporadically. In case 2 (b), abundant presence of pneumococcal capsules was observed. In case 3 (c) and case 4 (d), a moderate amount was seen. In the thromboembolus of the basilar artery of the case 4 (e), large groups of bacteria were present (arrow) in addition to isolated bacteria (with mix of macrophages and neutrophils). The group of bacteria was enlarged in inlet. f Abundant presence of pneumococcal capsules in a control meningitis case
