- Abstract
Introduction and Objectives: The spores of various species of fungi such as Cladophialophora, Aspergillus and Alternaria are distributed in air and are considered as important factor in allergenic diseases (airborne fungi). Therefore, long term exposure to spores of some fungi can cause different diseases such as asthma and broncopolmolary Aspergillus. Materials and Methods: In this study, air sampling was done from indoor and outdoor of 20 cattle and, 25 dwelling farms and 10 public places. After 5-7 days from incubation, the resulting colonies were counted and differentially diagnosed. Blood sampling and IgE assessment were done after giving registration forms from all the staffs who worked 6 hours per day at least in one year. Results: In all cultured plates the maximum numbers of counted colonies were specified to Cladophialophora, Aspergillus and Alternaria. Six of staffs showed allergic symptoms. IgE assessment determined that 5 and 3 of these staffs had specific IgE against Cladophialophora and Aspergillus, respectively. The assessed specific IgEs against Cladophialophora and Aspergillus were significantly correlated to each other (p < 0. 05). Discussion: In this study the most prevalent fungi which potentially are allergenic, in indoor and outdoor air of farms were determined. The results show that it is necessary to reduce the amounts of allergenic fungi in indoor air of farms by suitable air conditioning and decreasing of damp. Furthermore, based on the specific IgE analyses in staffs' blood serum, essential strategies should be considered in order to decrease the time of staffs' exposure with indoor air dusts of farms.
