RESUMEN
Airborne fungal pathogens such as Penicillium, Aspergillus, Cladosporium, Trichophyton, and Alternaria may cause health problems. In this research, the fungal flora at different bakeries and their potential allergenic effects on the workers were investigated. We investigated 148 workers at 17 industrial type bakeries and 62 workers at 17 home type bakeries in Afyon. Our study was performed in two different seasons and climates, between January 2004 and June 2004. Fungal flora was detected by using Petri-dish method. In the winter, Penicillium was the dominant genus, while Cladosporium was the dominant genus during the summer, in both types of bakeries. The allergenic properties of dominant culturable fungi on workers involved in the bakeries were determined with the skin-prick test. It was found that with workers in the industrial type bakeries, the most common skin test positivity was caused by Penicillium. In the other hand, the skin test positivity, performed on workers in the home type bakeries, was equally caused by Penicillium, Trichophyton and Aspergillus.
