Abstract
The systemic and local antibody responses to homologous strains of Moraxella catarrhalis were investigated in 14 children with otitis media. A total of 8 children (57%) demonstrated a rise in serum antibody of the immunoglobulin G (IgG) (5 of 14), IgM (5 of 14), or IgA (6 of 14) classes of immunoglobulin to outer membrane antigens. Local antibody consisted of IgG (100%), IgM (29%), and IgA (71%). The IgG and IgA specific antibody present in middle-ear effusions appeared to represent local production rather than passive diffusion from the systemic circulation. These data suggest that young children develop an antibody response to M. catarrhalis in the middle ear during otitis media but fail to develop systemic antibody in a uniform manner.Entities:
