Evaluation of the Yeast Traffic Light PNA FISH probes for identification of Candida species from positive blood cultures

J Clin Microbiol. 2012 Apr;50(4):1446-8. doi: 10.1128/JCM.06148-11. Epub 2012 Jan 11.


The Yeast Traffic Light PNA FISH kit (YTL) correctly identified Candida spp. in 207/216 (96%) positive blood cultures. Discordant results were seen with known cross-reacting species and cultures containing Candida lambica and Rhodotorula mucilaginosa. The YTL provides rapid, reliable identification of the five common Candida species found in blood cultures.
