The pathogenic bacteria\fungi available in dust storms of south–west of Iran have triggered and exacerbated various diseases. The aim of this study was to investigate the microbial flora of the dust storms and associated contaminations in three border cities: Gilan–e Gharb – Qasr–e Shirin – Sarpol–e Zahab ( Kermanshah, Iran ). The bacteria and fungi were initially separated using a specific media. The air sampling was directly performed through the Air Trapping method and Sedimentation was done from the respiratory balance level ( 1 meter height ). Teased mount and slide culture methods were applied for detecting the fungi. In this study , totally 25 sites from three twons of Gilangharb,Qaser–e–shirin,and sarpolezahab was considered to an there study from each site ,three plates in height respiratory ( 50cm,100cm and 150cm ) ( from the ground ) were employed . the results are as follows :35 out of 75 plates ( 46\66% ) had gram positive Cocci withe 50 plates ( 66\66% ) gram positive Bacilli and 7 plates ( 9\33% ) had gram negative Cocci,17plates of ( 24\28% ) gram negative Bacilli are held . the height frequnency was found from the gram positive Bacilli. The 75 plates are listedin 42 plate equivalent( 56% ) of fungi transparent,72plates of ( 96% ) of the mushroom color that fungus alternarya frequnency ( 42\66% ) of maximum frequnency and mushroom Rizopus and Zygomycetes with frequnency ( 13\33% ) had the lowest prevalence. . The number of gram–positive bacteria was higher than the gram negative ones, because of the higher resistance ability of these bacteria against critical conditions, environmental drought and also the bacilli's potential of sporulation. Furthermore, the existence of melanin pigments in Dematiaceous fungi with the ability to resist the harmful effects of sunlight is the main reason for the large number of this type of fungus.<\div>
