title: Characterization of a new coagulase-negative Staphylococcus species (Staphylococcus pettenkoferi) isolated from blood cultures from a hospitalized patient in Porto Alegre, Brazil.
abstract: BACKGROUND
  Staphylococcus pettenkoferi was originally isolated and described by Trülzsch et al (2002). In this study, we characterized two isolates of this newly described species.
  
  
  METHODS
  Blood cultures were initially processed using the BacT/ALERT(R) device, and the isolates were initially characterized using the Vitek2 identification system.
  
  
  RESULTS
  The initial characterization revealed slow-growing Gram-positive cocci that formed opaque colonies on sheep blood agar. Other phenotypic/genotypic tests were performed.
  
  
  CONCLUSIONS
  We would like to emphasize that this new staphylococcus species is phenotypically similar to other CoNS, especially S. auricularis. This could potentially lead to misidentification of these uncommon species.
