Opis:
We have investigated the hydrolytic activity of 21 species of yeast-like fungi from Candida genus and l species of yeast S. cerevisiae isolated from Sulejów Reservoir water. The activity of hydrolytic enzymes of the studied fungi was different than that of standard strains and also of fungi isolated from patients. This difference demonstrates the capability of the studied fungi to adapt to various environmental conditions.

Opis:
Progressive degradation of water ecosystems may contribute to the propagation of fungi pathogenic to humans and animals. The aim of this study was a quantitative evaluation and identification of species of potentially pathogenic fungi in the littoral zone of the Sulejów Reservoir used as recreation site. We studied samples of surface water and sediments collected from 6 sampling sites of the reservoir in the years 2000 and 2001. In 2000, fungi were isolated from 82.7% of samples, while in 2001 from as many as 95.4%. There were 28 species representing genera: Candida, Cryptococcus, Geotrichum, Kloeckera, Rhodotorula, Saccharomyces, and Trichosporon. The most common species were Rhodotorula glutinis and Candida guilliermondii. The density of the population of identified species depended on the season and sampling site and ranged from 80 to 328000 cells/dm³ (also uncountable growth). The waters of the Sulejów Reservoir may be a covenient place of anamorphic developmental forms, for the 15 cultured species which can also propagate in humans and other mammals.

Opis:
The hydrolytic activity of Rhodotorula and Trichosporon strains isolated from Sulejów Reservoir water and sediments were studied. Also tolerance of high concentrations of natrium chloride and biogenic compounds was evaluated. Fungi from genera Rhodotorula and Trichosporon showed the activity of 12 and 10 from 19 hydrolases of API Zym test, respectively. Tolerance tests showed high resistance of Rhodotorula glutinis to hypertonic saline solutions and very high resistance of both Rhodotorula and Trichosporon strains to nitrate, ammonium and phosphate compounds. These properties of fungi may influence the distribution and the quantity of fungi in aquatic reservoirs.

Opis:
We have evalueated the activity of acidous asparagine protease in 48 strains of Candida isolated from homogenates of palatine tonsils from 116 patients after tonsilectomy. Strains most frequently isolated were C. albicans (66.7±6.8 %) and C. tropicalis (14.6±5.09 %). The range of proteolysis zone for Candida strains was 4.6 to 12.5 mm. Over 60% of the studied strains showed high and very high proteolytic activity (>6.6 mm) and the remaining strains with showed moderate activity (4.6-6.5). There were no strains with low medium activity (to 4.5 mm zone). The range of the number of rosettes E formed by lymphocytes obtained from the studied tonsils was 0-268.3. Lymphocytes isolated from 70 % of tonsils infected with Candida formed only 0-130 rosettes E; in the remaining cases the number ranged between 131 and 220. The number of lymphocytes T forming rosettes E isolated from palatine tonsils from patients not infected with fungi was 2.5 times higher. There was no correlation between the size of proteolysis zone and the number of rosettes E.

Opis:
Formation of fungal biofilms in patients with implanted biomedical prosthesis constitutes very serious clinical problems. The biofilm can lead to dysfunction of implanted material and can be a reservoir for chronic and systemic infections. Numerous investigations demonstrated differences in quantity and structure of biofilms that had been formed by various species of fungi belonged to Candida genus. Stages of biofilm formations had been examined carefully in in vitro conditions. Biofilm formation begin with adhesion of fungi to the surface, microcolonies are formed subsequently. At the end of the process, extracellular material is excreted, and its formula, that is various in different fungi Candida species, contribute to its resistance to antifungal drugs. Farnesol and tyrosol are two quorum-sensing molecules. They are acting inversely, regulating formation of „germ tubes” and influencing morphogenetic conversion between yeast and filamentous forms, which plays a very important role in pathogenicity and formation of biofilm. Drug resistance of fungi from Candida has been shown to create a very important clinical problem. Many experiments in vitro confirm significantly lower activity of antifungal drugs toward Candida biofilm than toward Candida, in the form of planctonic cells. Surprisingly, some non-steroidal anti-inflammatory drugs can inhibit biofilm formation.

Opis:
The ability of Candida sp. cells to adhere to the mucosal surfaces of various host organs as well as synthetic materials is an important pathogenicity feature of those fungi which contributes to the development of infection. This property varies depending on the species of the fungus and is the greatest for C. albicans. The process of adhesion depends on plenty of factors related to the fungal and host cells as well as environmental conditions. The main adhesins present on the fungal cell wall are: Als, Epa, Hwp1, but also Eap1, Sun41, Csh1 and probably Hyr1; for adhesion significant are also secreted aspartyl proteases Sap. Various researchers specify a range of genes which contribute to adhesion, such as: CZF1, EFG1, TUP1, TPK1, TPK2, HGC1, RAS1, RIM101, VPS11, ECM1, CKA2, BCR1, BUD2, RSR1, IRS4, CHS2, SCS7, UBI4, UME6, TEC1 and GAT2. Influence for adherence have also heat shock proteins Hsp70, Mediator Middle domain subunit Med31 and morphological transition. Among factors affecting adhesion related to host cells it is necessary to mention fibronectins and integrins (receptors for Candida sp. adhesins), type of epithelial cells, their morphology and differentiation phase. To a lesser degree influence on adhesion have nonspecific factors and environmental conditions.
