Abstract: | The production of poultry has proved to be a significant source of fungi. Penicillium and Aspergillus are among the most important species, because they can cause irritations, infections, allergies, spoilage of food and beverages and are able to produce dangerous mycotoxins. Detection and identification of the species in these genera is very significant, because it provides relevant information about the properties of the responsible strains. Therefore, their taxonomic was determined using a phenotypic and molecular (ITS and partial β-tubulin sequences) methods. Investigations were conducted in the poultry house located near Wroc?aw in Lower Silesia (Poland). Using morphological analyses, 215 fungal strains were identified. Among them, 56 belonged to the Penicilium and Aspergillus genera. The results obtained from sequence analysis corresponded well with the morphological identification. Classification at species level was possible in most cases using the sequence data. Most isolates belong to Penicilium genus, with the follow dominating species (P. chrysogenum, P. polonicum and P. olsonii). |
