Moraxella catarrhalis has been emerged as a pathogen in the last decade. M. catarrhalis is an important pathogen in respiratory tract infections, both children and adults with underlying chronic obstructive pulmonary disease. The bacterium is a common cause of acute otitis media and sinusitis in children. Occasionally, the bacterium causes systemic disease. Bacteremia with M. catarrhalis has been documented rarely. We report a case of bacteremia M. catarrhalis in an immunocompetent children. Bacteremia due to M. catarrhalis has been reported in an immunocompromised patients, had underlying respiratory infections and immunocompetent hosts.
