Objective. To evaluate the biofilm formation by isolates of Candida spp. obtained from blood culture in patients with or without hematological malignancies. Materials and Methods. Biofilm formation by Candida spp. was determined by the method of Pierce C. and Tumbarello M. Isolates with optical density (OD) >0.1 were considered as biofilm-forming. Results. A total of 109 isolates of Candida spp. (C. albicans [n=22], C. parapsilosis [n=22], C. tropicalis [n=22], C.
