title: Sensitisation to Aspergillus fumigatus and Penicillium notatum in laboratory workers.
abstract: Four workers in medical research laboratories, located in a basement level of a University facility equipped with a humidified air conditioning system, complained of cough and/or asthma and/or rhinitis during their normal working activities. Since exposure to toxic compounds was very low (similar to that of the outdoor environment) only microbiological monitoring was performed. Aspergillus fumigatus and Penicillium notatum were found in some laboratories. Eight laboratory workers (including the 4 symptomatic subjects) out of 26 investigated were found to be atopic. Specific IgE sensitisation to Aspergillus fumigatus was found in the 8 atopic and in the 6 non-atopic workers, while Penicililum notatum was found in 7 atopic and 4 non-atopic subjects. History, physical examination and laboratory data excluded the presence of aspergillosis or allergic bronchial aspergillosis in the sensitised subjects. Our results suggest that evaluation of immune parameters, along with monitoring of the working environment, may reduce the risk of sensitisation and/or allergic symptoms in atopic laboratory workers.
