Since inhalation allergens are an important part of these allergens the aim of this study was to assess the prevalence of aeroallergens and their association with allergic diseases based on skin prick test (SPT).

Material and Methods: In this study, the frequency of these allergens were examined by using 22 aeroallergens and based on Skin Prick Test in 1100 patients with allergic diseases who referred to Shohadaye- Khalije- Fars university hospital.

Results: The reaction severity of SPT and the severity of disease associated with inhaled allergens with Russian thistle (21.1%, P꞊0.001), Chenopodium album pollen (14%, P꞊0.001) and Dermatophagoid Pteronyssinus (9%, P꞊0.001) respectively. Also, in these patients, the frequency of inhalation allergens were House Dust Mite (HDM) (69%), feather (60.8%), Russian this tle (59.9%) pollen and Alternaria mold (59.6%) respectively.

Conclusion: This study indicated that outdoors inhaled allergens  such as Russian thistle and Chenopodium album pollen have the most allergenicity in patients with allergic and asthma in Bushehr province, Meanwhile, the prevalence of indoor aeroallergens such as HDM, feather and mold were high in these patients.
