- Abstract
Introduction: Nosocomial infections are mainly associated with high morbidity and mortality rates in healthcare systems. The presence of airborne fungi in hospital environments is of great concern due to their potential role as a source of hospital-acquired infections (HAI). Therefore, this study aimed to determine and compare the concentration of Aspergillus species in indoor environment of a burn hospital in Sari, Iran. Materials and Methods: A cross-sectional analysis of Aspergillus was performed in a burn hospital in Sari, using the quick take 30 pump-air sampler and carpet sterile fragments for sampling of air and surfaces in different wards of the hospital (e.g., operating room, intensive care unit, as well as surgery and burn wards, respectively). Collected samples were cultured on petri dishes containing Sabouraud dextrose agar with chloramphenicol. Plates were incubated at 27-30°C for seven days. Grown Aspergillus spp. were identified in the level of species using morphological methods including macroscopic and microscopic characteristics. Results: In this study, a total of 42 samples were collected and cultured. Mean level of recovered fungi was determined at 25.7 CFU/m3. Assessment of samples obtained from the air, surfaces and healthcare setting revealed that Aspergillus spp. were the most common fungi. Moreover, a total of 38 Aspergillus were isolated. Among the different Aspergillus species, A. fumigatus (20.5%) was the most common, followed by A. flavus (17.9%), A. niger (7.7%) and A. clavatus (1.3%), respectively. Conclusion: According to the results of this study, A. fumigatus was spread as an important agent of nosocomial infections in hospital environments. It is recommended that contributing factors for the airborne fungal level in hospital environments be properly managed to minimize the risk of HAIs.
