Sphingomonas paucimobilis, which was previously named as Pseudomonas paucimobilis in 1977 as an etiologic agent of human infection, is a nonfermenting gram-negative bacillus found in soil and water. Limited reports of S paucimobilis infection have been documented to date. Especially, nosocomial infections are common, and generally, adults are the primary victims. It was rarely reported in childhood. In this case report, a 22-month-old immunocompetent boy who had had S paucimobilis bacteremia complicated with sepsis and associated meningitis was reported. Our patient had no history of immunosuppression or associated disease. The patient had been treated with ceftriaxone for the diagnosis of acute otitis media at a local clinic. Upon admission, the initial blood culture was identified as S paucimobilis, which was sensitive to the antibiotics being administered. S paucimobilis infections have favorable prognosis, and at outpatient visit, our patient had revealed no sequela.
