Candida species are of common occurrence in the buccal cavity and these yeasts are present in about 50% of healthy individuals. This percentage can change depending on the studied population. The infectious processes caused by Candida vary of benign clinical pictures, to serious and fatal pictures as the invasive infections and disseminated. In this study it was evaluated the colonization of yeasts of the Candida genus on 312 saliva sample of the hospital workers from "Hospital das Clínicas da Universidade Federal de Goiás" in the city of Goiania-Goiás/Brazil, during the period from July to December of 2007. Candida species were identified by production of germ-tube, chlamydospore formation, assimilation sugar tests and culture on CHROMagar^® Candida. The hospital workers analyzed presented colonization of the saliva by yeasts of the Candida genus in 61.9% from samples studied, being isolated C. albicans (58.5%), C. parapsilosis (24.4%), C. krusei (8.3%) and C. famata (3.6%). The publication of these results can serve as an aid for the prevention and control of oral candidiasis in the workers of the area of health that live in contact with individuals susceptible to infections.
