This report described a case of Moraxella catarrhalis bacteremia in a previously healthy 11-month-old boy. Seven-valent pneumococcal conjugate vaccine (PCV7) and Haemophilus influenzae type b (Hib) conjugate vaccine had been administrated 3 times, respectively. His clinical symptoms were fever, mild cough and nasal discharge. M. catarrhalis was detected by blood culture and he was diagnosed with M. catarrhalis bacteremia. He didn't have any underling disease, such as congential cardiac disease or immunodeficiency. He responded well to 7-days course of intravenous antimicrobial therapy. Although M. catarrhalis is an uncommon cause of bacteremia in healthy children, it should be considered as one of bacteremic pathogens especially in children who have completed PCV7 and Hib conjugate vaccine.
