| Four isolates of Sclerotinia sclerotiorum were tested for pathogenicity in IPA-10 variety bean plants (Phaseolus vulgaris L.), and all were pathogenic. Biological control in vitro was evaluated using eight isolates of Trichoderma spp. and, one of Ulocladium atrum. Chemical control in vitro with fungicides Thiophanate methyl, Iprodione and Carbendazim was also tested. Except U. atrum, all Trichoderma isolates showed antagonistic potential against S. sclerotiorum, where isolate 3601 presented the best performance. Thiophanate methyl chemical control was the most efficient. This fungicide and isolate 3601were compared in vivo in greenhouse. There was statistical difference between the treatments, and the application of fungicide and antagonist before the... |

| Five mutants (MaE10, MaE27, MaE24, MaE41 e MaE49) of Metarhizium anisopliae wild strain E9 were analysed for DNA profile through the RAPD technique and for changes in total protein content by spectrophotometry, polyacrylamide gel electrophoresis and densitometry. The pattern of RAPD markers showed genetic polymorphism among the strains: out of twenty primers seven were selected, producing 113 bands. Forty seven bands were present in all strains (41.6% of monomorphic bands) and 66 showed polymorphism (58.4%). The mean coefficient of similarity among all strains was 0.75 (75%). The total protein content varied, staining in the interval of 6.0-8.0 µg/µl. The electrophoresis analysis, through zymogram and protein fraction profiles by densitometry, allowed the... |

| Abstract Aspergillus fumigatus is an opportunistic saprobe fungus that accounts for 90% of cases of pulmonary aspergillosis in immunosuppressed patients and is known for its angiotropism. When it reaches the respiratory tract, A. fumigatus interacts with structural components and blood vessels of the lungs, such as elastin. To understand the effect of this structural component, we examined the effect of elastin on the production and development of the biofilm of A. fumigatus. In RPMI containing 10 mg/mL of elastin, a significant increase (absorbance p < 0.0001; dry weight p < 0.0001) in the production of biofilm was observed in comparison to when RPMI was used alone, reaching a maximum growth of 18.8 mg (dry weight) of biofilm in 72 h. In addition,... |
