Description
Summary:	Atmospheric air is the most common vehicle for the dispersion of fungi. Fungi belonging to the genera Aspergillus and Penicillium are cosmopolitan and are classified in the family Trichocomaceae. Species of the genera are commonly found in soil, decaying organic materials, animal feed, stored grains, and other materials. This study aimed to determine the taxonomic diversity of airborne fungi of the genera Aspergillus and Penicillium residing in the dust of library environments to contribute to current knowledge of these characteristic genera. Three libraries in the city of Cuiaba, State of Mato Grosso, Brazil, were selected as the study areas. A total of 168 samples were collected at randomized sites within each library in areas containing journals, archives, in study rooms, and in collection storage areas in two different periods, the dry season (n = 42) and the rainy season (n = 42). Samples were collected by exposing Petri dishes containing Sabouraud agar with chloramphenicol to the environmental air. Additional samples were collected with sterile swabs which were rubbed over the surface of randomly chosen books on the shelves; the swabs were subsequently incubated in the laboratory. The genus Aspergillus was highlighted as one of the principal airborne fungi present in indoor environments. Aspergillus spp was identified in 1,277 (89.6%) samples and Penicillium spp in 148 (10.4%). The dry period exhibited a greater number of isolates of the two taxons.
