Three new basidiomycetous yeasts, Pseudozyma alboarmeniaca sp. nov., Pseudozyma crassa sp. nov. and Pseudozyma siamensis sp. nov. isolated from Thai patients.

We previously reported the first isolation of Pseudozyma species from the blood of Thai patients. In this study, three additional new Pseudozyma species were isolated from clinical specimens from Thai patients. The Pseudozyma species showed relatively low sensitivity to azole antifungal agents. The names proposed for these isolates are Pseudozyma alboarmeniaca (DMST 17135(T)  = JCM 12454(T ) = CBS 9961(T)), Pseudozyma crassa (DMST 17136(T ) = JCM 12455(T)  = CBS 9959(T)) and Pseudozyma siamensis (DMST 17137(T ) = JCM 12456(T) CBS 9960(T)), where DMST is Department of Medical Sciences Culture Collection, JCM is Japan Collection of Microorganisms and CBS is Centraalbureau voor Schimmelcultures.
