Opis:
Candida is a yeast species recognized as the most frequent etiological agent of systemic and invasive thrush in humans. Invasions can affect all tissues, organs and systems of human in various stages of development. In the last 10 years Candida infections have increased 15 times. The purpose of our study was to determine the sensitivity of four antibiotics belonging to three different groups of antifungal agents against clinical and food-borne Candida strains. Our studies showed that of all tested strains, 7% was resistant to nystatin, 32% to fluconazole, 23% to voriconazole, and no strains grew in the presence of caspofungin. Despite the differences in biochemical profiles of clinical and food-borne isolates of Candida, a group of strains showing resistance to antibiotics include both types of isolates. At the same time circulating of antibiotic-resistant strains outside the hospital environment and the yeast infection via food is possible.

Opis:
Processes of colonization of biotic and abiotic surfaces and biofilm formation depend inter alia on hydrophobic properties of Candida spp. The aim of this research was to determine the effect of tea tree, thyme and clove essential oils on hydrophobic properties of environmental and clinical Candida isolates. The relative cell surface hydrophobicity of strains tested was high, and ranged from 68.7% to 91.2%, with the highest value for a C. rugosa food-borne strain. The effectiveness of essential oils was diversified and depended on the type of essential oil, concentration and yeast strain. Statistically significant decrease of hydrophobicity indexes was observed after application of tea tree oil for C. krusei, clove oil for C. albicans reference strain, and all essential oils tested for C. rugosa. Only in the case of C. famata food-borne strain and C. albicans clinical isolate, solely used essential oils did not affect their hydrophobic properties. To determine the interactions of essential oils, their mixtures (1 MIC:1 MIC, 1 MIC:2 MIC and 2 MIC:1 MIC) were applied. Generally, essential oils used in combinations influenced yeast's hydrophobic properties much more than applied separately. The essential oils' mixtures reduced hydrophobicity of Candida yeasts in the range of 8.2 to 45.1%, depending on combination and strain. The interaction indexes of essential oils used in combinations predominantly indicate their additive effect. The application of tea tree, thyme and clove essential oils, especially in combinations, decreases hydrophobicity of the tested Candida isolates with implications of a probable advantageous limitation of their ability to colonize the food production industry environment.
