ICU N2 - Introduction: Invasive aspergillosis is the most threatening disease inimmunoco-mpromised patients which has the highest morbidity and mortality rate among invasive fungal infections in the hospitals. The aim of present study was to assess antifungal susceptibilitytesting versus Aspergillus spp isolated from the hospitals environment. Materials & Methods: After collecting 160 plates containing Sabouraud dextrose agar from the air and the environment of hospital's ICUs (intensive care units), the phenotypic and molecular identification of the colonies was performed for the identification of Aspergillusspp. After DNA extraction, the molecular identification was carried out using universal fungal primers (ITS gene) and DNA sequencing. Antifungal susceptibility testing was performed using the CLSI broth microdilution (M38-A2) method for Aspergillus isolates. Findings: Out of 160 hospital environmental samples, 11Aspergillus species were obtained. The eleven Aspergillus spp. were identified by sequencing as: 5 A. flavus, 3 A. sydowii, 1 A. fumigates and 2A. Oryzae. Our antifungal susceptibility testing results indicated that A. sydowii and A. fumigatus were sensitive to Amphotericin and Voriconazole and also were resistant to Itraconazole. A. sydowii was resistant to Caspofungin while A.fumigatus was sensitive to this drug. A. flavus was susceptible to all the drugs. Discussion & Conclusions: There were a number of reasons including delayed diagnosis, lack of appropriate curing, and the existence of various diseases and neutropenia which could lead to the high mortality rate of patients with Aspergillosis, especially in patients of hospital's ICUs.
