RESUMO
We investigated the occurrence of yeast species isolated in a public hospital. We researched the presence of C. dubliniensis and investigated the species within the complex Candida parapsilosis and studied this complex in relation to biofilm´s production. We also investigated the factors related to virulence and studied the sensibility profile by the \"Etest ®\" method. During the years of study, C. albicans was the most isolated yeast with 36.45% followed by C. tropicalis 23,36%, C. parapsilosis sensu stricto 21,49%, Pichia anomala 5,61%, C. guilliermondii 4.67%, C. krusei 2.80%, C. orthopsilosis 1.87%, C. glabrata 1.87%, C. metapsilosis 0.94%, C. pararugosa 0.94%. C. dubliniensis was not isolated in this study. In the study of Candida parapsilosis complex, C. parapsilosis sensu stricto was the most prevalent species. Only eight strains of C. parapsilosis sensu stricto and one strain of C. orthopsilosis produce biofilm. The non-albicans species showed greater activity of the proteinase and hyaluronidase than C. albicans. In the study of hemolysin and phospholipase, C. albicans was the most producer. All strains were susceptible to amphotericin B and to fluconazole four were resistant. For caspofungin, two strains were resistant.
