Abstract:
Culture-based identification and antifungal susceptibility take 48-72hours after positivity. We analyzed the performance of Vitek2 directly from 40 yeast-positive blood-cultures; agreement of 100% was observed for the tested antifungals; identification showed the same species in 31/40. The method reduces time (13 to 18h) for preliminary results.
