E-mail: baroni@ufrrj.br The objective of this study was to check the presence of yeasts from genus Candida in the oropharynx of ostrichs (Struthio camelus) and also evaluate in vitro production of virulence factors. This observation is relevant considering the extension of this kind of production and the lack of knowledge about the microorganisms and potentially infectious agents that this large bird. The animals were divided into four groups, according to their age, totalizing 80 samples. The sample collection was performed using swabs and processed in Sabouraud Dextrose Agar. After the isolation of positive samples, the yeasts were identified by macromorphology and micromorphology evaluation and also assimilation and fermentation tests, added to complementary proofs. From the total of samples, 32.5% showed the presence of yeasts, alone or with molds. The identification of C. albicans corresponded to 65.38% of the isolates. The major part of isolates was strongly positive for production of protease and approximately half of these were also producers of phospholipases, what suggests the potential of virulence even in commensal agents.
