<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">The air of animal dwellings can contain great amounts of bioaerosol composed of dust, bacteria, fungi, and endotoxins. The composition may depend on animal species, building construction, animal accommodation, and microclimate parameters, to name just a few factors. Pathogens contained may be a serious threat to animal and human health.The aim of our study was to analyse the fungi aerosol content in a stable housing dairy cows and in a coop for laying hens over the three autumn months of 2007. The air was sampled on Petri dishes with Sabouraud glucose agar. After laboratory treatment, we identified the most common fungi. Their count in the stable ranged from 3.98×103 CFU m-3 to 5.11×104 CFU m-3 and in the coop from 6.89 ×104 CFU m-3 to 1.13×105 CFU m-3. The difference between the two animal dwellings was statistically different at the level of p&lt;0.05. In both dwellings, the most common were the fungi <italic>Aspergillus</italic> sp., <italic>Penicillium</italic> sp., and yeasts, followed by <italic>Cladosporium</italic> sp., <italic>Fusarium</italic> sp., <italic>Mucor</italic> sp., <italic>Scopulariopsis</italic> sp., <italic>Alternaria</italic> sp., and <italic>Rhizopus</italic> sp.Our results are entirely in line with values reported in literature and are at the lower end of the range. They call for further investigation that would eventually lead to setting air quality standards for animal dwellings and to developing reliable monitoring systems in order to ensure safe food and safe environment.</abstract>
