title: Bacteremic Moraxella catarrhalis pneumonia in a patient with immunoglobulin deficiency.
abstract: A-75-year old woman with agammaglobulinemia developed Moraxella catarrhalis bacteremic pneumonia. M. catarrhalis pneumonia is rarely associated with bacteremia, and neutrophils have been reported as a significant factor in the host defense system against this bacteria. This case suggests that immunoglobulin also plays a key role in the host defense system against M. catarrhalis.
