Abstract: The authors analyze incidence of non-albicans Candida species and non-Candida species isolated from cancer patients. The results of examination shown that presence of 9 non-albicans Candida spp. and non-Candida spp.: C.parapsilosis (n=20), C.tropicalis (n=9), C.krusei (n=4), Cr.neoformans (n=2), C.claussenii, C.intermedia, C.mogii, C.pulcherrima and C.zeylanoides (n=1 each). Classifying the sample according to the patient`s diagnosis, the yeasts were most frequently isolated from patients with leukemia (n=14), with non-specified cerebral tumor (n=6), Hodgkin`s disease (n=3), squamous cell carcinoma of oral cavity (n=3), myeloma (n=2), and other neoplastic diseases (lymphoma, non-specified tumor of larynx, nasal cavity and middle ear, colon tumor, non-Hodgkin´s lymphomas, breast cancer). Regarding the localization of samples in which the above yeasts were detected, most frequently the positive samples were found in swabs taken from oropharyngeal region (n=11) and blood (n=10).
