[Serratia marcescens multifocal osteomyelitis in a child with chronic granulomatous disease].

Chronic granulomatous disease (CGD) is a rare primary immuno-deficiency. It is characterized by an alteration in the function of phagocytes causing recurrent bacterial and fungal infections. This is a case report of a child with multifocal osteomyelitis by Serratia marcescens, an infrequent as a cause of bone infections, although associated with CGD. The study of infections with clinical presentation and unusual agents should lead to suspicion of CGD. The diagnosis early in life, as well as timely antimicrobial treatment and the subsequent antimicrobial prophylaxis will avoid infectious recurrences and sequelae.
