The increasing incidence of severe fungal infections highlights the need for rapid and precise identification methods in clinical mycology. The aim of this study was to develop and validate a culture-indipendent molecular approach that could allow the detection of fungal pathogens in clinical samples, with particular attention to the identification of drug-resistant Candida and Aspergillus species. A real-time multiplex PCR assay was developed using TaqMan probes specific for highly discriminating ITS sequences. In its multiplex format the assay showed a high specificity, clearly discriminating among different species, as well as a high sensitivity (20 CFU/1 mL sample), making it a potentially useful starting point for the development of a more complete molecular diagnostic assay.
