Rare/cryptic Aspergillus species infections and importance of antifungal susceptibility testing.

Background: The number of patients infected with Aspergillus rose dramatically in recent years. However, studies on the clinical spectrum and antifungal susceptibilities of non-classical (non-fumigatus, non-flavus, non-niger and non-terreus) pathogenic Aspergillus species are very limited.

Objectives: We examined the clinical spectrum and antifungal susceptibilities of 34 non-duplicated, non-classical Aspergillus isolates collected from Hong Kong, Shenzhen and Shanghai.
