Abstract: 

Despite growing evidence of the importance of exposure to fungi as an environment risk factor for asthma, there is not any report on the identification of airborne fungi of asthmatic patients living in Iran inner cities. The aim of this study was identification of fungi in indoor and outdoor of asthmatic patients’ home. Opened plates (containing of malt extract agar media) were used for isolation of fungi in the air of indoor (n = 360) and outdoor (n = 180) of 90 asthmatic patients’ home living in the city of Sari at the level of breathing height. Plates were incubated in room temperature for 714 days. Then grown fungi were identified by standard mycological techniques. Totally, 1866 colonies with 31 different genera of fungi and 1683 colonies with 27 different genera of fungi were isolated and identified from indoor and outdoor of asthmatic patients’ home, respectively. The most common isolated genera were Cladosporium (29.20%), Aspergillus (19.03%), Penicillium (18.27%), Sterile hyphae (11.26%) and Alternaria (6.65%) in indoor air of the houses of asthmatic patients; whereas, Cladosporium (44.50%), Aspergillus (12.42%) and Alternaria (11.11%) had the most frequencies in the outdoor of the houses of asthmatic patients. Among the Aspergillus species, Aspergillus flavous had the most frequency. Cladosporium, Aspergillus, Penicillium, and Alternaria as the most common allergenic moulds had the most frequencies in indoor air of the houses of asthmatic patients. Since in cities, people spend the most of their times in indoor environment, therefore, indoor airborne fungi has an important role in fungal-induced diseases like asthma.
