摘要: Mucosal and systemic antibody responses to pneumococcal capsular polysaccharide were studied in 17 children with culture-verified acute otitis media. Serotype-specific antibody-secreting cells (ASCs) peripheral blood antibodies convalescent sera nasopharyngeal aspirates measured. A polysaccharide-specific ASC response was induced all subjects. The age dependent, the dominant class IgA. Three > 24 months old had 100 IgA-class ASCs/10(6) serum IgA responses; 2 only a response. None of 8 < showed response; however, detected 1. Results suggest that whole pneumococci can induce mucosal independent are also accordance earlier studies suggesting immune system matures life than does
