| Abstract [eng] |
Aim of the work was to determine the distribution of Candida yeasts in various substrates and the surrounding environment, to define their biological characteristics and preventive measures to reduce the pollution. During the study 498 yeast isolates from soil, water, phyllosphere, food products, human body and the surrounding residential and occupational environment were isolated and identified. It was revealed that they belong to 21 genera and 63 species. Candida yeasts comprised 31% of all isolated yeasts; new to Lithuanian mycobiota species were recorded: C. magnoliae, C. saitoana, C. oleophila and C. sorboxylosa. Assess the Candida yeast morphological, physiological and biochemical characteristics. Acute toxicity/pathogenicity of single doses of C. albicans (C.A.4) and C. parapsilosis (C.P.1) administered per os or intraperitoneally to warm-blooded animals was ascertained. Assessment of the impact of 11 disinfectants and 8 antifungal preparations on pathogenic Candida yeasts was conducted. The effects of 12 essential oils, Pantoea citrea (T1x, T2x, T3x), Streptomyces sp. (Ux, Ux308) on Candida yeasts were determined. |
