[Fungi isolated from the stool in patients with gastrointestinal disorders in 2005 - 2009].

The mycological examination of 2242 stool specimens sampled form patients with non-specific gastrointestinal tract ailments was focused on the spectrum of fungal species isolated in culture, the frequency of isolation of the particular species high enough to indicate microbiological imbalance in the gut flora as well as evaluation of the fungal susceptibility to the antifungal agents. Fungal presence was detected in 61.5% of the specimens tested. The fungal flora isolated was as follows: C. albicans 70.9% of the isolates, Candida non-albicans 20.8% (including C krusei 3.40%, C. parapsilosis 1.88%, C. glabrata 1.59%), other genera 8.34% (including S. cerevisiae 5.58%, Geotrichum sp. 1.16%, and Trichosporon sp. 1.01%). The results of semiquantitative evaluation of the intensity of growth of the fungi isolated from the stool revealed that imbalance in the gut flora occured in 20.8% of the cases. Candida strains tested using Fungitest were less susceptible to azoles than to amphotericin B and 5-fluorocytosine. Decreased susceptibiliy or resistance to antimycotics was relatively often found among Candida non-albicans strains.
