| Opportunistic fungi are those that normally would not cause diseases in otherwise healthy people, but are able to cause problems under some circumstances, and for this they need to possess a certain virulence potential. The objective of this study was to identify samples of filamentous fungi isolated from poultry barns in Cascavel, Paraná, and also to evaluate their virulence potential by assessing proteinase production, hemolytic activity, urease production, and growth rate at 37 ºC. We have evaluated the following samples: Acremonium hyalinulum (1 sample), Aspergillus sp. (12), Beauveria bassiana (1), Curvularia brachyspora (1), Paecilomyces variotti (1), and Penicillium sp. (2). Out of the 18 samples analyzed, 44.4% showed proteolytic activity using... |
