Methods: Forty-four pairs of dental casts stored since 1980e1981 were used. The material for microbiological analysis was collected with a swab and cultivated in brain-heart infusion cultures and Sabouraud dextrose broth for subsequent plating and colony identification. Results: Bacterial growth such as coagulase-negative Staphylococcus, Micrococcus sp., Bacillus sp., and nonfermenting gram-negative bacillus were present in 25% of the samples, whereas fungal growth such as Cladophialophora sp., Trichosporon beigelii, Aspergillus flavus, and Aureobasidium pullulans were found in 5.7%. Conclusions: There was growth of opportunistic bacteria and fungi, posing no risk to healthy people165-168engBacteriaFungiPlaster castArtigo10.1016/j.ejwf.2013.07.003Acesso restrito8223795731605246
