ABSTRACT
Enterobacter sakazakii previously known as a 'yellow-pigmented Enterobacter cloacae', was designated as a unique species in 1980. This reclassification was based on differences from E. cloacae in DNA relatedness, pigment production and biochemical reactions. In 1961, Urmenyi and Franklin reported the first two known cases of neonatal meningitis and septicemia caused by E. sakazakii, although at that time it was still considered as an E. cloacae strain. Since 1961, a number of cases of neonatal infection caused by E. sakazakii have been reported worldwide. Usually newborn with E. sakazakii meningitis have a poor prognosis, many of them dying within days of infection. The reported case-fatality rate vary from 40-80%. We diagnosed and experienced a case of epidural abscess caused by E. sakazakii in a 1 month old male patient, who was asymptomatic with brain mass detected on brain ultrasound examination. We presented this case with a brief review of literatures.
