| Abstract: | Information about airborne fungal spore is crucial for health risk assessment and management, especially for patients with allergy and asthma. Nonetheless, such data are rarely available from certain areas of the world, including Southeast Asia. The aim of this study was to gain updated information about airborne fungal spore in Bangkok, the capital city of Thailand. A survey was conducted at five sampling sites in Bangkok, using the Rotorod Sampler® for a period of 1 year. High concentrations of spores were found all year with the peak between August and November. The most prominent spore types were Cladosporium, Nigrospora, Puccinia, Aspergillus/Penicillium, and Fusarium. The spore concentrations were positively and significantly correlated with the amount of rainfall and relative humidity, reaching the maximum level in September. Sensitization rates to Cladosporium, Penicillium, and Aspergillus among Thai atopic patients were approximately 16.6, 13.6, and 13.0%, respectively. |
