Importance of pathogenicity Aspergillus and Mucor fungal species in Duststroms in zabol area

Background: Fungi are the air polluter organisms that can cause many diseases, including superficial diseases, opportunistic and systemic infections, allergic reactions, rising up the allergies and etc. Regarding the importance of diseases caused by airborne fungi, this study aims to identify the diversity and frequency of fungal flora in the province of Zabol in 1396.Methods: In this descriptive and cross-sectional study, sampling with 540 plates containing suborudextros agar containing chloramphenicol medium from five areas of Zabol in two seasons of spring and summer was carried out from active and out-of-field environments. For detection of colony Fungal culture was applied using culture method and the results were analyzed using Fisher test.Results: In this study the most common fungi which were divided from the internal and external environment in the spring and summer were aspergillus fumigatus (20.8) and mucor (19.5). The highest fungal concentrations in the indoor and outdoor environment of Aspergillus fumigatus (Cfu: 285.37) and Mucor (Cfu: 289.15) were in the external and internal media of Aspergillus fumigatus (Cfu: 275.45) and Flavus (Cfu: 265.45) fungi. There was a significant difference between the prevalence of fungi in both summer and spring in both indoor and outdoor environments (P = 0.000). The concentration of Fungus Flora with temperature and wind speed was inversely correlated with moisture content.Conclusion: The results of this study showed that the air of Zabol city contains different types of fungal spores, therefore, considering that fungi can cause various diseases in humans and also are important causes of pathogenicity and mortality in immunocompromised individuals. Therefore, knowing the diversity of fungal flora in different places and identifying the environment from the point of view of fungal flora to infectious specialists, skin, doctors, etc. will be helpful in preventing, treating and reducing the mortality of diseases caused by human contact with fungi
