Abstract
Pneumococcal capsular polysaccharide vaccines may be a novel way of treating patients with recurrent sinusitis. To evaluate the pneumococcal capsular polysaccharide types of strains causing sinusitis, 55 pneumococcal strains isolated from maxillary sinus effusion were analyzed. The most frequently occurring types were 3 (13%), 19F (11%), 6B (9%) and 23F (9%).
