Evaluation of VITEK 2 for Discriminating Trichosporon Species: Misidentification of Trichosporon non-T. Asahii

Diagn Microbiol Infect Dis. 2014 Sep;80(1):59-61. doi: 10.1016/j.diagmicrobio.2014.05.017. Epub 2014 May 21.

Abstract

The VITEK 2 system was evaluated for the identification of 74 Trichosporon invasive and non-invasive clinical isolates, comparing its results with the IGS1 sequencing. The system correctly identified Trichosporon asahii but not non-T. asahii isolates, which represented nearly 50% of the invasive infections in our nosocomial setting.

Keywords: Misidentification; Sequencing; Trichosporon; VITEK 2.
