Abstract

Candida parapsilosis sensu stricto, Candida orthopsilosis and Candida metapsilosis are human fungal pathogens with clinical importance. The recently reclassified three closely related species have significant variation in virulence, clinical prevalence and susceptibility characteristics to different antifungal compounds. The aim of this study was to investigate the in vitro activity of atorvastatin and fluvastatin against C. metapsilosis, C. orthopsilosis and C. parapsilosis. Susceptibility tests showed that C. parapsilosis was the most sensitive while C. orthopsilosis was the least susceptible species to both drugs. On the basis of the differential sensitivity, we developed a simple, reliable and highly cost-effective plate assay to distinguish these closely related species. Applying this method, 54 isolates belonging to the C. parapsilosis sensu lato complex deposited in Szeged Microbial Collection could be sorted into the three species with 100 % probability.
