In 1995–2000 we examined in the mycological laboratory 8663 specimens for fungal infection by microscopical examination cultivation. The species was identified by the germ-tube test, fermentation and assimilation of carbohydrates. We examined 3421 specimens of faeces and found fungal infection in 37%, the most common was Candida albicans and Geotrichum candidum. In 1736 specimens of sputum and bronchial lavage, yeast microorganisms were isolated in 48%, mostly Candida albicans. In 2697 specimens of skin and mucous membranes in 26% we found fungal microorganisms. We examined 550 samples from the external ear, 40% was mycologically positive, the most common infectious agent of otomycosis was Aspergillus sp. Among 87 specimens from eyes we isolated molds- Acremonium sp., Fusarium sp. and Penicillium sp. Among 123 samples of urine, 41% were mycologically positive, most common was Candida albicans. In 49 blood samples yeasts were found only three times.
