Abstract
We describe a series of Ralstonia pickettii bloodstream infections (BSI) that occurred in 19 oncohematologic patients admitted to a hospital for patients with cancer, in the city of Rio de Janeiro, from July 1999 to February 2006. Fifty-four R. pickettii isolates were recovered from blood and catheter-tip specimens (1–5 isolates per patient). Two patients eventually died of causes unrelated to R. pickettii BSI. Eight pulsed-field gel electrophoresis genotypes were resolved (A–H), with two detected in more than 1 patient: genotype B, in 2 patients (1.5%), and E, in 12 patients (63.2%). R. pickettii emerged as a new pathogen at our institution, causing at least one outbreak. Cross-transmission of the pathogen, infusion of a putative contaminated intravenous solution, and persistent colonization of medical devices were the likely sources of R. pickettii BSI.
