[Case report: nosocomial Ralstonia pickettii infection in neonatal intensive care unit].

Although Ralstonia pickettii was known as a saprophytic species, it has been isolated in nosocomial infections in recent years. In this case report, R. pickettii infection of a neonate in the neonatal intensive care unit (ICU) was presented. R. pickettii was isolated from the blood cultures of the neonate and also from the incubator and distilled water of the incubator. The isolates revealed identical biochemical and physiological characteristics. The strains were identified by conventional tests and by API ID32 GN system. There was no other newborn infected by R. pickettii in the ICU during the same period. In conclusion, R. picketti should be taken into consideration as an etiologic agent especially in ICU infections. To prevent outbreaks, sterile solutions used for patient care and other possible sources must be investigated regularly.
